Go’s concurrency features are powerful and easy to use, but
that same ease can sometimes lead even seasoned developers to make
mistakes.
Fortunately, the Go ecosystem comes equipped with useful tools for
debugging, e.g., the race detector,
but even existing tools may miss some concurrency bugs,
such as the topic of this article, the goroutine leak.
Goroutines synchronize or exchange information
via shared concurrency primitives, e.g., channels, locks, and wait groups.
While communicating, goroutines often block on these primitives,
as in, wait until some condition is met;
ubiquitous examples include waiting to acquire a held mutex,
or receive a message over a channel.
Goroutines can also block on operating system operations, like reading from a network socket or a file.
We may consider a goroutine leaked if it is blocked,
but the conditions needed to unblock it can never be met.
Over time, an accumulation of leaked goroutines degrades
performance through excessive memory usage (by the leaked
goroutines themselves or the memory they reference), as well as
CPU usage from the garbage collector, especially
if GOMEMLIMIT is in use.
Goroutine leaks can be notoriously difficult to detect.
In unit testing, the most significant breakthroughs include
the open-source library goleak,
which can instrument individual tests to signal any
un-terminated goroutines after the test wraps up as suspicious.
Similarly, Go 1.25 introduced the synctest package to
the standard library; it can significantly improve
the quality of unit tests in concurrent code by giving
Go developers more control over the ordering of concurrent events
in order to reliably test hard-to-reproduce scenarios.
Unfortunately, neither approach can check for goroutine leaks
in production systems, especially at larger scales,
which may behave in ways unaccounted for by tests.
Goroutine profiles are a rudimentary way to check for operations
that block too many goroutines, or analyze growth trends.
However, goroutine profiles cannot distinguish between
goroutines which are leaked, and those which are temporarily blocked
in high numbers by design, e.g., as caused by increased
traffic in a microservice.
Likewise, leaks which are low in number may slip by undetected for many years.
Go 1.27 introduces the goroutine leak profiler,
a flexible and lightweight mechanism for finding
goroutine leaks in running Go programs, including production systems.
Unlike previous approaches, which require human analysis,
this mechanism is precise and generates little-to-no false positives.
The trade-off is that it is limited to a subset of goroutine leaks:
goroutines permanently blocked on channels or primitives
in the sync package.
Luckily for us, this already covers a very large subset of goroutine leaks,
as we’ll see in our examples.
In the following sections, we showcase how to use the feature, followed by
some additional examples of detectable leaks, and a description of the
underlying implementation and trade-offs.
Example: concurrent workers
Consider a function that processes work items concurrently:
typeresultstruct{resworkResulterrerror}funcprocessWorkItems(ws[]workItem)([]workResult,error){// Process work items in parallel, aggregating results in ch.
ch:=make(chanresult)for_,w:=rangews{gofunc(){res,err:=processWorkItem(w)ch<-result{res,err}}()}// Collect the results from ch, or return an error if one is found.
varresults[]workResultforrangelen(ws){r:=<-chifr.err!=nil{// This early return may cause goroutine leaks.
returnnil,r.err}results=append(results,r.res)}returnresults,nil}
Because ch is an unbuffered channel, each worker goroutine blocks when sending
its result until the main goroutine receives from the channel.
If processWorkItems returns early due to an error, the receiving loop terminates,
and all remaining sender goroutines block forever.
This example is emblematic of a common mistake discovered in real Go programs,
including Uber production services.
Let’s see how we can find these leaks by using the
new goroutine leak profiler.
Debugging with the goroutine leak profiler
The profile is available through the
runtime/pprof package, as the
goroutineleak profile type, or by installing the profile handlers defined
by the net/http/pprof package.
If you already have net/http/pprof set up in your service,
then you don’t need to do anything else! The profile will be
automatically made available for collection at the /debug/pprof/goroutineleak
endpoint on whatever host and port the handlers are installed.
Let’s put our concurrency bug in context and set up the net/http/pprof package.
This way, you can try it yourself!
packagemainimport("errors""log""net/http"_"net/http/pprof""time")typeworkIteminttypeworkResultintfuncprocessWorkItem(wworkItem)(workResult,error){time.Sleep(10*time.Millisecond)ifw==5{return0,errors.New("simulated error")}returnworkResult(w*2),nil}typeresultstruct{resworkResulterrerror}funcprocessWorkItems(ws[]workItem)([]workResult,error){ch:=make(chanresult)for_,w:=rangews{gofunc(){res,err:=processWorkItem(w)ch<-result{res,err}}()}varresults[]workResultforrangelen(ws){r:=<-chifr.err!=nil{returnnil,r.err}results=append(results,r.res)}returnresults,nil}funcmain(){// Start pprof server
gofunc(){log.Println(http.ListenAndServe("localhost:6060",nil))}()// Repeatedly trigger the leak
for{items:=[]workItem{1,2,3,4,5,6,7,8,9,10}_,err:=processWorkItems(items)iferr!=nil{log.Printf("Error processing items: %v",err)}time.Sleep(time.Second)}}
Build the program above, then run it:
$ go build -o leaky
$ ./leaky
Collecting the profile
It won’t take long for the program to start accumulating
leaks, which you can then view by using the web UI
at http://localhost:6060/debug/pprof.
Alternatively, you can collect the goroutine
leak profile using curl, and then examine it with go tool pprof:
$ curl http://localhost:6060/debug/pprof/goroutineleak > leak.prof
$ go tool pprof leak.prof

. . 34: }()
The profile reveals the goroutines leaked at
ch <- result{res, err} (line 33), pinpointing the culprit operation.
Notably, the longer the program is running, the larger the number of leaked
goroutines.
Addressing the leak
This leak can be simply fixed by giving ch a buffer:
ch:=make(chanresult,len(ws))
This allows all the work item goroutines to send a message without blocking
in the event of a premature return of processWorkItems.
This section is for those interested how leak detection
works under the hood of the goroutine leak profiler.
For details strictly pertaining to performance overhead and limitations,
skip ahead to this section.
Core concept
Let’s start with an initial observation: if a goroutine
is blocked over some concurrency primitive that no other goroutine has access to
(in this case, via a reference in memory), then it is obviously leaked.
This is already a strong lead, we can generalize it further into a definition
for when a goroutine is not leaked, a property we term as liveness.
We formally define liveness, an inductive property
as follows:
A goroutine is live if:
it is not blocked by a concurrency primitive, or
at least one concurrency primitive that blocks it is referenced
by another live goroutine.
In the trivial case, goroutines which are not blocked are obviously
not leaked.
In the inductive case, the underlying assumption is that
any goroutine which is not leaked may eventually use
concurrency primitives it references to unblock any
other goroutines blocked by those primitives.
To find all live goroutines, we start from the obviously live
unblocked goroutines and trace any references
they hold, i.e., through their local variables, to find
the concurrency primitives they have access to.
We then incrementally include any goroutines blocked over those
primitives as live, and repeat the process until no
additional live goroutines are discovered.
Fortunately for us, the Go runtime already computes memory reachability
through the garbage collector (GC),
so the next step is to adapt the GC to suit our purposes.
You can quickly compare the two GCs with the following diagrams:
A complete overhaul of the GC is not necessary.
The Go runtime uses a concurrent tri-color mark-and-sweep garbage collector,
(now with the Green Tea variant!),
so its MO already neatly aligns with our goals.
Only a few key changes are needed:
In the initial phases, the regular GC marks all goroutines (and global variables)
as reachable, such that they would never be considered garbage,
i.e., they are mark roots.
We change it to instead only include unblocked goroutines,
since these are guaranteed to be live.
This is followed by the marking phase, where the GC traces objects referenced
(transitively) by the mark roots, and marks them as usable memory.
Even though we do not modify this phase directly, the changes in step 1.
implicitly ensure that the GC only marks memory referenced by live goroutines.
The marking phase is finalized by inspecting all the blocked
goroutines not included as mark roots in step 1.
If a goroutine is blocked by at least one concurrency
primitive that has been marked in step 2., it is added as a mark root,
and the GC resumes the marking phase from step 2.
This coincides with the inductive step in the definition
of liveness.
Once all live goroutines have been discovered, any goroutine
which has not been added as a mark root has its status set to leaked.
The marking phase then resumes one last time with all the leaked goroutines
added as mark roots, allowing the GC to mark all the memory it would have
marked during a regular run.
Once the GC cycle is complete, the goroutine leak profiler picks up
like in a regular goroutine profile, and filters for strictly
leaked goroutines.
Limitations
The examples above demonstrate the usefulness of goroutine leak profiles.
Nevertheless, the garbage collector has some limitations that may lead
it to miss leaks:
Memory overreach: if a concurrency primitive is
consistently reachable through global variables or runnable goroutines,
then goroutines blocking on it are never reported as leaked, even if
that concurrency primitive is never used in the future.
This can be alleviated by better regimenting access to
concurrency primitive references, and more clearly
delineating their lifecycle.
Non-standard blocking:
For the sake of correctness, goroutine leak detection is strictly limited
to Go first-class concurrency primitives, which includes:
channel send and receive operations (including over nil channels),
blocking select statements, i.e., with no default case, up to, and including
select statements with no cases, and members of the
sync package, specifically Mutex,
RWMutex, WaitGroup and Cond.
Goroutines blocked for any other reason, e.g.,
file and network IO, or direct system calls
are never considered as leaked.
This likewise applies for custom, user-defined concurrency,
e.g., spin locks, unless they rely on the primitives outlined above
for their underlying implementation.
Non-determinism: leaks can be detected only after
they have occurred, but cannot be otherwise predicted,
so reproducing and diagnosing leaks in flaky programs
continues to be a challenge.
For the best results, we encourage mixing approaches, by using
goroutine leak profiles at various layers, up to, and including production,
as well as comprehensive test suites instrumented with goleak and synctest.
Performance impact
Goroutine leak detection is carefully designed to minimize
performance impact, but there are, nevertheless, some costs.
While memory overhead is negligible, only limited to small additions
required for bookkeeping, goroutine leak detection can be slower
than the regular GC.
This is best illustrated through a pathological case we
call the “daisy-chain”:
In this leak-free example, runnable goroutine G₀ has a
reference to primitive P₁ which blocks G₁, and so on.
This implies that proving liveness for some Pᵢ₊₁,
requires proving liveness for Pᵢ, which introduces
two costs:
The GC marking phase is effectively serialized relative to the
order in which goroutines can be scanned, as all the memory reachable
from some Pᵢ must be marked before Pᵢ₊₁ can be added as a root.
The inspection currently checks all blocked goroutines
at the end of each marking round, for a worst-case of O(n²) steps for one
GC cycle, where n is the total number of goroutines.
While the second point can eventually be optimized for,
the first point is an intrinsic limitation of leak detection
that cannot be circumvented.
Regardless, we remind the reader that, unless configured otherwise
via runtime flags, the GC still operates concurrently with user code.
Furthermore, if a goroutine leak can be observed at some point in time, then it
can also be observed at any future point during the same execution.
Periodic profiling infrastructures can therefore tune profiling frequency,
e.g., every 4 hours, to minimize overhead at virtually no cost in
leak detection capabilities.
The transition from academic prototype to actual Go feature was made possible
with the guidance of Michael Knyszek and Michael Pratt on the Go team at Google, and
PJ Malloy (@thepudds).
Additional examples
The following are coding patterns that lead to leaks, as
observed in industrial-scale codebases and open source projects,
in ascending order of complexity.
You can quickly test drive the goroutine leak detector on them in
the Go playground, as well as
experiment with your own leaks.
Example: Double send
Some of the simplest leaks occur when more messages
are sent over a channel than expected.
Below, a goroutine is expected to send one message to the main goroutine
over an unbuffered channel.
However, the return statement is missing after the send operation
in the error case.
For every error, the sender will, therefore, attempt to send two messages,
which causes a leak.
funcDoubleSend(){ch:=make(chanany)gofunc(errerror){iferr!=nil{// In case of an error, send nil.
ch<-nil// Return statement is missing.
}// Otherwise, continue with normal behaviour.
// This send is still executed, which causes a leak in the error case.
ch<-struct{}{}}(fmt.Errorf("error"))// Receive only one message.
<-ch}
While the profile does not explicitly highlight the missing return
as the cause, it at least directs you to the faulty function, by
highlighting the leaking send operation.

. . 123: }
. 1 126: ch <- struct{}{}
. . 127: }(fmt.Errorf("error"))
. . 129: <-ch
This leak can be addressed simply by adding a return statement after the
send operation in the error case.
Example: Early return
The inverse situation is just as common, where the receiver
omits communication on some control flow paths,
in what is effectively a simplified version of the introductory example.
// Incoming error simulates an error produced internally.
funcEarlyReturn(errerror){ch:=make(chanany)// Create a worker goroutine.
gofunc(){// Send something to the channel.
// Leaks if the parent goroutine terminates early.
ch<-struct{}{}}()iferr!=nil{// The parent goroutine quits too early in case of an error.
// Sender leaks.
return}// Receive is only executed if there is no error.
<-ch}
The goroutine leak is exposed by the profile:

. . 140: go func() {
. 1 143: ch <- struct{}{}
. . 144: }()
. . 145:
. . 146: if err != nil {
The leak can be addressed by giving ch a buffer of size 1.
Example: Timeout
A variation of the Early return pattern above involves contexts
and non-deterministic choice (select statements):
funcTimeout(ctxcontext.Context){// An unbuffered channel is used to coordinate
// a worker and parent thread
ch:=make(chanany)// Create worker goroutine
gofunc(){// Perform some work then signal to the parent thread.
ch<-struct{}{}}()// Wait for message from worker or context
// to be cancelled or timed out.
select{case<-ch:// Receive message from worker
case<-ctx.Done():// Sender leaks because there is no
// future rendezvous over the channel.
}}
If the context is cancelled before the sender synchronizes with the parent,
the sender will leak:

0 10 (flat, cum) 100% of Total
. . 198: go func() {
. 10 201: ch <- struct{}{}
. . 202: }()
As in the previous example, the fix is to give the channel
buffer of size 1.
Example: Range over channel without closing
Iterating over channels by using range
allows you to repeatedly receive values from a channel in a loop.
Once the channel is closed and all values that have been enqueued
in the channel’s buffer have been received, the loop exits.
Importantly, if the channel is never closed, a range loop will block
the executing goroutine forever.
Omitting the close operation is a common mistake, as below:
// Incoming list of items and the number of workers.
funcnoCloseRange(list[]any,workersint){// Create a channel that distributes work items.
ch:=make(chanany)// Create the worker goroutines.
fori:=0;i<workers;i++{gofunc(){// Each worker pulls items from the channel
// and then processes it.
foritem:=rangech{// Process each item
_=item}}()}// Queue items to the workers by using the channel.
for_,item:=rangelist{// The parent leaks by sending an item if workers == 0
// or if all the workers panic, but the panic is recovered.
ch<-item}// Otherwise, the channel is never closed, so workers
// leak once there are no more items left to process.
}...gonoCloseRange([]any{1,2,3},3)// Leaks all 3 workers
A goroutine leak profile for such a program would include the following:
Type: goroutineleak
(pprof) list noCloseRange.func1
Total: 4
ROUTINE ======================== main.noCloseRange.func1 in .../main.go
0 3 (flat, cum) 75.00% of Total
. . 82: go func() {
. 3 84: for item := range ch {
. . 86: _ = item
. . 87: }
. . 88: }()
We see the 3 workers blocked at the range ch operation, which
gives an ample hint as to the cause of the leak. The leak can be
addressed by simply closing the channel once all messages have been sent:
for_,item:=rangelist{ch<-item}// All items have been sent. It is now safe to close.
close(ch)
Bonus! Eagle-eyed readers may have spotted another potential
leak in this example, if the number of workers is mistakenly set to zero,
which will lead the parent sender to leak:
gonoCloseRange([]any{1,2,3},0)// Sender leaks with 0 workers
This is also captured by the profile:
(pprof) list noCloseRange$
Total: 4
ROUTINE ======================== main.noCloseRange in .../main.go
0 1 (flat, cum) 25.00% of Total
. . 76:func noCloseRange(list []any, workers int) {
...
. . 92: for _, item := range list {
. 1 95: ch <- item
. . 96: }
While workers > 0 can be assumed to hold in realistic production systems,
goroutine leak profiles can nevertheless be used to implicitly monitor for off-chance
violations without conservative workers <= 0 checks.
Example: Method contract violations
The patterns seen so far have been relatively constrained in their lexical scope.
However, as functionality is spread out across functions, methods and packages, and
implementations are obfuscated by interfaces, the difficulty of manually detecting
leaks drastically increases.
Such a case is exemplified in this section, with the custom worker type that embeds two channel
fields, ch and done and creates a looping goroutine with its Start method that
reads from both channels with a select statement.
Said goroutine can only be terminated by receiving a message through the done channel,
which is closed by the Stop method.
The Start method can be invoked any number of times, but if it is invoked
at least once, Stop should eventually be called.
As a result, Start and Stop form an implicit contract that dictates the order
in which the methods should be invoked.
Breaking that contract can lead to undesirable behavior,
in this case, goroutine leaks:
funcMethodContractViolation(){items:=make([]any,10)// Create a new worker
w:=NewWorker()// Start worker
w.Start()// Operate on worker
for_,item:=rangeitems{w.AddToQueue(item)}// Exits without calling ’Stop’.
}typeworkerstruct{chchananydonechanany}typeWorkerinterface{Start()Stop()AddToQueue(itemany)}funcNewWorker()Worker{return&worker{ch:make(chanany),done:make(chanany),}}// Start spawns a background goroutine that extracts items pushed to the queue.
func(w*worker)Start(){gofunc(){for{select{case<-w.ch:// Normal workflow
case<-w.done:return// Shut down
}}}()}func(w*worker)Stop(){// Allows goroutine created by Start to terminate
close(w.done)}func(w*worker)AddToQueue(itemany){w.ch<-item}
This issue is further exacerbated in practice, where such custom types are only
exported as interfaces, in this case, through the non-descript
Worker type.
Clients may not even be aware of the underlying implementation and,
consequently, violate the implicit contract without realizing.
Fortunately, soliciting a goroutine leak profile can reveal the defect:
(pprof) list Start

. . 271: return
Naturally, the fix involves following the trail to the Start call
and adding an invocation of Stop.
Example (Cockroach): Missing unlock
The following example
is taken from CockroachDB.
It involves acquiring and releasing a lock in a loop,
but forgetting to unlock it
before executing a break statement:
typeGossipstruct{musync.Mutexclosedbool}func(g*Gossip)bootstrap(){for{g.mu.Lock()ifg.closed{// Missing g.mu.Unlock
break}g.mu.Unlock()}}funcCockroach584(){g:=&Gossip{closed:true,}// ...
g.bootstrap()g.bootstrap()// Causes a leak
}
In such a case, the goroutine will leak when failing to acquire the lock.
(pprof) list Gossip

ROUTINE ======================== main.(*Gossip).bootstrap in .../main.go
0 1 (flat, cum) 100% of Total

. . 168: if g.closed {
. . 170: break
. . 171: }
. . 172: g.mu.Unlock()
Adding a call to Unlock before the break addresses the issue.
Example (etcd): Unexpected channel operation orderings
This example,
found in etcd,
shows how an unexpected ordering between channel
operations can lead to a goroutine leak:
The run method fires a loop which expects to
repeatedly receive messages over the status channel
(sent by invoking the Status method).
At the same time, it can also receive one message over the
stop channel (sent via the Stop method),
at which point it closes the done channel and exits.
The Stop method itself then waits to receive message
over done, which is unblocked once done is closed.
A leak may occur if the run, Status, and Stop methods
run concurrently.
The Stop and run goroutines can synchronize
and exit without receiving the message issued
by Status, causing it to block forever.
(pprof) list Status
Total: 8
ROUTINE ======================== main.(*node).Status in .../main.go

. . 17: c := make(chan struct{})
. 8 18: n.status <- c
. . 19: return <-c
. . 20:}
Wrapping the send to status in a select statement
where the other case branch tries to receive a message
over done allows the goroutine running to Status
to gracefully exit if it lost the race with a Stop
call.
Example (Kubernetes): Mutual blocking between channels and mutexes
This example
occurs in Kubernetes,
as a result of mixing channels and locks:
The goroutine running WriteFrame may acquire the
idle-aware framer lock, followed by sending a message over the
resetChan channel, while the monitor goroutine
waits to receive a message over the closeChan channel.
Once a message has been dispatched, the monitor goroutine
will attempt to acquire the same lock.
However, since there isn’t any traffic over resetChan, the send operation
blocks forever, preventing the monitor goroutine from releasing
the lock.
This, in turn, causes both goroutines to leak.

. . 22: var resetChan = i.resetChan
. . 23: for range i.conn.closeChan {
. 100 24: i.writeLock.Lock()
. . 25: close(resetChan)
The fix is to set up a separate goroutine after a message is received
over closeChan in the monitor goroutine that drains the resetChan
before attempting to acquire the lock.
typeManagerstruct{plugins[]int}func(pm*Manager)init(){vargroupsync.WaitGroupgroup.Add(len(pm.plugins))for_,p:=rangepm.plugins{gofunc(pint){defergroup.Done()}(p)group.Wait()// Block here
}}funcMoby25384(){pm:=&Manager{plugins:[]int{1,2},}gopm.init()}
The group wait group increments its counter
depending on the number of plugins held by the
plugin manager pm, then iterates over each plugin
and spawns a goroutine.
Each goroutine decrements the counter once it finishes
its task with the Done method.
However, group erroneously invokes Wait inside
the loop body, instead of after it!
This will cause any goroutine running the init method
when the manager has more than one plugin to leak.

This can be easily addressed by moving the Wait outside
the loop.
Example (Moby): Mutual blocking between channels and mutexes
Another example
in Moby
showcases a mixed channel-lock leak:
The goroutine invoking StateChanged may acquire the lock
of the container stored by the daemon, then invoke
the updateHealthMonitorElseBranch method on
the daemon, which attempts to send a message over
the stop channel of the container.
However, the goroutine running monitor
may fail to receive a message over stop, if the message
is not already in-flight, and instead unblock by picking
the default case of the select statement.
This will lead it to try to acquire the same container
lock that is already held by the StateChanged
goroutine, leading both goroutines to leak.

. . 87:}
The fix is to close the stop channel instead
of sending a message over it.
Since closing a channel is not a blocking operation,
the StateChanged goroutine is then able to release
the lock.
In turn, this unblocks the monitor goroutine,
which may now terminate by picking unblocked
<-stop case branch in the select statement
on the next loop iteration.

Our cookie auditor acts like a privacy-conscious user by visiting web pages and checking that they only load cookies consistent with that user’s preferences.
Read more
As AI and automation become a bigger part of digital experiences, it’s increasingly important that people stay in control of the choices they make. They should be able to benefit from new technology without losing the preferences they’ve already expressed.
Cookie banners are one of the most familiar places where people express those preferences online. They’re also one of the most visible parts of a company’s privacy program. And for companies that operate a large, dynamic collection of websites, keeping them working as intended can be challenging. A banner might work correctly when a page launches, but changes made later can affect how someone’s cookie preferences are saved or applied. When someone accepts, declines, or customizes cookies, the website needs to remember that choice and behave accordingly. New integrations, experiments, or even changes to a page’s settings can unintentionally affect that behavior.
Manually checking that cookie banners continue to work as expected across all of our websites requires hours of quality assurance. To make those checks more manageable, we built a cookie auditor that acts like a privacy-conscious user. It visits Dropbox web pages and checks that they only load cookies consistent with that user’s privacy preferences. This gives us a scalable way to put our privacy commitments into practice as our web presence continues to evolve.
Challenges in cookie banner compliance
Most of us are familiar with cookies, but we don’t always think about what they mean for the choices we make online. Cookies are small pieces of data sent to a browser when someone visits a website. Some are strictly necessary, meaning they serve an essential purpose like keeping a user logged in or remembering language settings. Others are non-essential and support things like analytics, marketing, performance, or advertising. Strictly necessary cookies load automatically, but privacy laws in some places require companies to get consent before loading non-essential ones.
On the surface, cookie compliance can seem pretty straightforward. Websites show a banner, provide buttons to accept or decline, record the choice, and load cookies accordingly. But at scale, things can get a bit more complicated. Dropbox operates over 200 web surfaces across different products and teams, and the cookies on each page can vary depending on that surface’s purpose. URLs also change all the time as pages are launched, retired, redirected, localized, or included in experiments.
Plus, cookie banners aren’t the only way people can communicate their privacy preferences. Global Privacy Control (GPC), for example, is a technical standard that lets people set a privacy preference in their browser that can be communicated automatically to the websites they visit. Our system needed to recognize GPC signals and respect those preferences, too.
It’s also important to look beyond cookie banners themselves. Even when a banner appears to work correctly, we still need to verify that someone’s choice is actually being applied. That means checking which cookies load before and after someone makes a selection, and that their preference continues to apply after the page reloads. That’s where our cookie auditor comes in.
Turning privacy requirements into testable rules
Before we began building a cookie auditor, our Privacy and Engineering teams first needed to agree on what the system should consider correct behavior. That meant deciding which websites should be audited, what kind of banner behavior would constitute a violation, and which third-party cookies and other artifacts should be tracked separately. We also defined when a missing banner should be considered a problem and when it was expected, such as on a web page that was no longer in use.
Privacy programs often depend on legal concepts that require human interpretation, such as opt-in or opt-out, strictly necessary, and affirmative consent. But a machine needs much more concrete instructions about what should happen when someone makes a particular choice and what to flag when something doesn’t behave as expected. Turning those concepts into outcomes the cookie auditor could actually test was an important part of the work.
We also kept these classifications outside the auditor’s source code. That meant the Privacy team could update the list of approved cookies and known exceptions without waiting for engineers to change the code and release a new version. Importantly, it also made the system easier to adapt as Dropbox services and regulatory guidance evolve, helping our privacy protections keep pace with both.
Because we built our cookie banner in-house rather than using an off-the-shelf product, we could integrate the auditor directly with our existing consent infrastructure. That gave us more control over how the auditor and consent system worked together and made it easier to adjust what we tested as our websites, services, and privacy requirements evolved. Instead of treating compliance as a fixed set of rules, we built a system that could change along with those requirements.
Testing the experience like a user
Defining the criteria that’d govern our cookie auditor was only one part of the challenge. We also needed a way to test those criteria against what someone really experiences when they visit a Dropbox website. To do that, we designed the auditor to behave much like a real visitor would. It uses Playwright, a browser automation library, to open a Dropbox web page in a fresh, isolated browser session and observe what happens from the moment the page loads.
For every page we check, the cookie auditor runs three separate tests to account for different privacy experiences. One simulates a standard US visitor, another simulates a visitor in the EU, and the third uses a GPC signal. Each test starts from scratch, with no existing cookies or saved preferences, so the auditor sees the same experience as a new visitor. Before interacting with anything on the page, the auditor records which cookies have already loaded and checks whether they match what we expect to see for that test.
Next, the auditor finds the page’s consent controls and declines non-essential cookies. That’s more complicated than simply looking for a button that says “Decline.” Depending on the page, consent controls might appear in a banner, a floating control, a preferences window, or a footer link. They can also appear in any of our 22 supported languages. Rather than relying on specific words on the screen, the auditor identifies and interacts with the underlying consent controls. It then reloads the page and checks what happens next.
Reloading the page is an important part of the test. Once the page reloads, the auditor checks that the user’s preference still applies and that the cookies present match what we expect for that test. If anything unexpected appears, it’s recorded for further review. This focus on what actually happens, rather than what should happen based on a configuration, became one of the project’s most important design decisions.
Discovering what we weren’t testing
At this point, we had a reliable way to test whether a Dropbox web page was respecting someone’s privacy choices. But the auditor could only test the pages we knew about. As new pages were created and existing ones changed, we also needed a reliable way to identify which pages should be included in our audits.
Although the auditor worked well on our defined list of URLs, we soon realized that keeping that list up to date would be an ongoing challenge. New marketing pages, blog posts, and help center articles are published every week. Our Privacy team didn’t necessarily have clarity on every new web surface being created across the company, and asking teams to manually send us every new URL would create exactly the kind of bottleneck the project was meant to reduce.
Our solution was a companion URL detector, which is effectively an auditor for our auditor. The cookie auditor checks whether a user’s decision is respected, and the URL detector makes sure we’re checking all the places where the consent experience should appear.
We started by using traffic data to identify Dropbox web properties. Because that data includes a new record every time someone visits a page, our initial search had to comb through billions of records. But billions of visits didn’t mean billions of different pages. The same URL path might appear thousands or even millions of times, so we first filtered out repeated records to narrow the results down to a more manageable list of unique paths.
From there, we applied a second, more detailed round of filtering. Doing all of that work while searching through billions of traffic records would have required significantly more time and computing resources, but working from the smaller list made it much more efficient. At this stage, we could exclude pages that didn’t need to be tested, group together pages that used the same consent logic, and select representative URLs from large groups of similar pages. This gave the cookie auditor a manageable set of pages that still represented the different consent experiences someone might encounter across Dropbox.
Automation can narrow the search space, gather evidence, and identify potential issues, while Privacy and Engineering teams provide the insight needed to understand unusual pages and exceptions. This division of labor helps us keep pace with Dropbox’s changing web footprint without creating another time-consuming manual process for our teams. It also reflects a principle behind how we approach automation and AI at Dropbox: Use these tools to surface relevant information so that people have the context they need to make informed decisions and take action, while spending less time searching for and sorting through it.
Privacy as a continuously validated practice
Privacy programs rely on policies, controls, and review processes, but people ultimately experience them through the products they use. When someone makes a choice about their data, they expect the product to respect it. That means making the choice clear, making declining as easy as accepting, remembering the preference, and applying it consistently as someone moves across a website.
That’s why we think about privacy much like reliability or security. It requires ongoing attention as products and systems change. Building the auditor showed us just how many pieces needed to work together to make that possible. We needed to know which pages to test, distinguish real issues from false positives, translate legal requirements into behavior that the auditor could check, and test the experience from a user’s perspective rather than relying on how a system was configured.
Over time, that changed how we thought about the auditor itself. It gave us a way to turn our privacy commitments into something we could regularly test against the actual experience people have on our websites. For us, building that trust into a changing product means making clear commitments to users and designing systems that continuously verify we’re upholding them.
Today, the auditor gives our Privacy and Engineering teams a weekly report on consent behavior across Dropbox websites. It separates likely violations from known false positives, making it easier for teams to understand what needs their attention. Historical results also help us track trends and spot when something that was working correctly begins to change. Our next step is to make that process even more efficient by connecting findings to the teams responsible for those pages and getting potential issues to the right people more quickly.
For teams considering a similar project, the browser automation itself may be the simplest part. Much of the work happens around the browser automation, including defining what correct behavior looks like, maintaining a reliable inventory of what needs to be tested, separating real issues from noise, and creating a review process that brings the right teams together. Investing in those pieces has given us greater confidence that our cookie program continues to work as intended, even as the websites and systems around it change.
