Sentry vs Airbrake: An Error Monitoring comparison for 2026

Two bugs crashed my bookstore API on the same line. One tried to read book.title from a missing book. The other tried to read coupon.discount from a missing coupon. Both raised a TypeError in server.js:81, but they needed different fixes.

Sentry created two issues. Airbrake created one group. Airbrake counted all 23 occurrences in my first run, but combined 13 book failures and 10 coupon failures. I had to build a custom aggregation on a breadcrumb field to uncover the second bug.

That difference matters more than the number of checkmarks on a feature page. A merged group can send you to the wrong fix, while a neatly separated issue can still mislead you if its event count is incomplete.

Airbrake concentrates on error tracking and route-level performance. Sentry links errors to traces, profiles, logs, metrics and release activity. In my test, Sentry made investigations easier, but Airbrake was simpler to operate and preserved more of the raw error occurrences.

I instrumented the same Node.js/Express application with both SDKs, exercised six failure scenarios and two slow paths, then inspected grouping, diagnostics, search, triage, releases and performance. These are observed results from October 20–21, 2026, not promises about every SDK or account plan. Prices and feature availability can change. The test did not independently validate Sentry's AI assistant or every third-party integration.

The practical verdict: Choose Sentry when diagnosis, ownership and cross-signal investigation matter most. Consider Airbrake when you want basic error monitoring, straightforward route statistics and fewer concepts to manage. The biggest caveat: neither dashboard count should automatically be treated as the true number of failed requests.

Detailed feature comparison

How I tested

The test app is a small bookstore API called monitoring-lab, built with Express on Node.js. I seeded it with six bugs and two slow paths so both tools had the same things to find:

Versions and setup:

I ran a common traffic script against both implementations. For the second phase, I used version 1.1.0 and tested what happened when previously resolved errors returned. Airbrake received an explicit deploy notification; Sentry received a release value through its SDK, but no separate deploy event.

How to interpret the numbers: The error scenarios were shared, but the timing, randomized upstream latency, repeated runs and product-specific instrumentation were not perfectly controlled. This is a comparative hands-on test, not a statistically matched latency benchmark. A missing field or view means it did not appear in my tested configuration, unless I explicitly cite broader product support. Some instrumentation, particularly custom Sentry spans and logs, was added by me rather than captured automatically. Don't compare totals across different test windows as if they came from a single run.

Getting started

Signing up

Sentry let me start a Business Plan Trial with no card, and the "14 Days Left" banner stayed in the corner the whole time. Onboarding leads with setup through a coding agent, marked "Recommended", for Claude Code, Codex, Cursor or Grok. I took the manual path so I could see each step.

The step that matters is "Connect your code". I chose "Continue without a repo", and that cost me two things later: Seer wouldn't run, and releases showed 0 commits. Stack traces still showed source lines, because the Node SDK read them from disk.

The product picker is also where Sentry tells you what you keep once the trial ends:

Airbrake asked for a card before the account was active. The activation screen read "Create a password and add payment information to finish your Airbrake account activation", and the form below it wanted a card number, expiry date, security code and billing email next to the password, followed by a 30-day free trial and a starting plan with "10 users, 3 teams, 20 projects, 25K errors, and free 50K APM events" at a base price of $38 a month. If your company makes you file a request every time a card goes into a vendor form, that's a real speed bump before you've seen a single error.

Once you're in, Airbrake creates an empty "First project" for you. I sent my data to a project I made called Monitoring, so the account dashboard listed both, with the first one sitting at zero. There's no product picker, because errors and performance are the only two things Airbrake collects.

Instrumenting the app

How you wire an SDK into your app is mostly your own choice, so I won't hold my setup against either tool. What matters is what each SDK gives you out of the box.

Both followed the same pattern in Express: initialize with your key, then add an error handler after your routes. Sentry's init turned on errors, tracing, logs and profiling from one config block, with profiling as an extra package. Airbrake's middleware gave me errors and route performance and nothing else to configure.

The real difference is what's built in. Sentry has calls for setting a user, adding breadcrumbs, wrapping code in a span, sending logs and recording metrics. Airbrake's Node notifier has none of those, so the user and breadcrumbs went into each error's context and params as plain data. That's why they show up as JSON later in this article.

Airbrake required less configuration in this test. Sentry took more work, but I got substantially more diagnostic context from the resulting events.

Already on the Sentry SDK? You can try Better Stack without re-instrumenting. I pointed the same monitoring-lab adapter at a Better Stack DSN and changed nothing else. All six bugs arrived as six separate errors, with the title and discount TypeErrors kept apart, source lines shown inline, and the checkout breadcrumbs and user attached.

Point your Sentry SDK at Better Stack

Capture and grouping

The first important difference was not whether the tools caught an error. Both did. It was whether the error inbox reflected the number of underlying bugs.

Sentry created six issues for six bugs. The title TypeError and the discount TypeError landed as separate issues, 66-5 and 66-3, even though both point to server.js line 81. The two Sentry issues retained enough fingerprinting context to stay separate in this test. Grouping depends on event attributes, SDK behavior and configuration, so this result should not be generalized to every same-line exception.

Airbrake put both TypeErrors in a single group. After the first run it showed 23 occurrences. After the second run it showed 46. The group title followed whichever error came in last, so the same row flipped between "Cannot read properties of undefined (reading 'title')" and "...(reading 'discount')" depending on timing. I could not find a split or merge action in the Airbrake interface I tested, so I could not correct the grouping there.

Airbrake did handle the job error well. Each run of the sales report produced a slightly different message, and Airbrake's messagePattern grouping still collapsed them into one group.

Sentry discarded some consecutive duplicates

Here's something that surprised me, and it cuts against Sentry. In my first run, the app threw 58 request errors and Sentry received 46. The other 12 showed up in Stats as "Client Discard / Event Processor". The Stats page classified them as "Client Discard / Event Processor". The pattern is consistent with SDK-side duplicate-event processing, but that Stats label alone does not prove which processor discarded each event.

In a later run, the log line for the title bug fired 14 times but the issue counted 10 events. For the discount bug it was 12 logs and 9 events. The application log lines gave me a separate count of the failing operations in this run. Airbrake counted every occurrence: its 23 lined up exactly with 13 plus 10.

The 1.1.0 run repeated the pattern. During the burst, Stats showed 46 accepted and 9 client discards. The two TypeErrors lost events because the traffic fired them back to back, while errors with varying messages, like the 503s and the rejections, came through one for one.

The discard counter establishes that some events never reached Sentry. The log view provides a second check: repeated application log messages remained visible even when the corresponding error events were deduplicated. These are different signals, so I would not use either count as a substitute for request-level failure metrics.

Better Stack's AI SRE caught this gap without being asked. I started an investigation from the coupon error, and in under a minute it counted 21 exceptions against 23 failed POST /checkout requests in the logs, then broke the failures down by coupon: lowercase save10 10 times, BLACKFRIDAY 7 and FREEBOOKS 4. It worked from errors, traces and logs together, with no repository connected.

Investigate errors with AI SRE

What this means: In these bursts, Sentry's captured event count was lower than the number of errors logged by the app. If you use event frequency for prioritization, inspect SDK-side discards and sampling settings before treating issue counts as request-failure counts. Airbrake matched the logged occurrences in this particular test, but that does not establish an absence of ingestion limits or filtering in other environments.

The error detail page

A correctly grouped issue is only the starting point. The next question is how much context you get before opening your editor.

Stack traces

Sentry showed the crashing line, server.js:81:45, with source lines 76 to 86 right there in the frame. It read the code from the files on disk at runtime, so I didn't need to connect a repository or upload anything. One in-app frame was expanded and eight Express framework frames were collapsed under it.

Airbrake pointed at the same line but showed no code. The occurrence carried sourceMapErrors with "unsupported URL scheme file", indicating that source retrieval failed in this environment. I got a file path and line number, but no inline source excerpt. That is the observed result, not proof that Airbrake can never display source context.

Breadcrumbs, user and context

I added two breadcrumbs before the coupon bug: "checkout started" with the coupon code, then "book found". Sentry rendered them as a timeline at the top of the issue, so I could read "checkout started {coupon: BLACKFRIDAY}" and know the cause in one glance. In Airbrake, the same breadcrumbs ended up as a raw JSON array inside params, which is where my filter had to put them.

Airbrake retained the breadcrumb values, but not as a navigable timeline. To reconstruct the checkout sequence there, I had to expand the parameters and interpret the JSON rather than scanning a dedicated breadcrumb view.

Airbrake has one thing on its error page that Sentry doesn't: the route's error rate. The TypeError group showed "11.76% error rate from 85 requests to this route: POST /checkout". That tells you how bad the bug is in proportion to traffic without leaving the page.

Sentry's answer is that the issue page links straight into logs and the trace. For the coupon bug I could see the request, the related log lines and the trace from the same screen.

Handled, unhandled and async errors

Sentry marks unhandled errors with a red "Unhandled" label. Handled ones carry no label and show "handled yes" with "mechanism generic" in the tags. When you scan the list, the crashes stand out from the errors your code caught on purpose.

Airbrake makes no such distinction. The OutOfStock error I reported on purpose looks exactly like the TypeError that crashed the request. Worse, manual notices showed ROUTE as "POST UNKNOWN" with a "Try it for FREE" performance upsell beside it, even though performance monitoring was already on.

The unhandled promise rejection is a good stress test. Sentry tagged it with mechanism auto.node.onunhandledrejection and showed the frame "server.js:144:9 in loadRecommendations". Airbrake caught it but kept one frame.

Airbrake reported the rejection too, so capture was not the problem. The difference was how much of the failure path I could inspect afterward: the Airbrake view exposed only a single backtrace frame in this run.

One confusing result deserves a caution: the rejection displayed only IP ::1 as its user context, while a tag drawer showed bob@example.com. I could not establish from the UI alone whether this was an inherited tag, test instrumentation problem or product display issue. Verify the underlying event before using a user attribution to debug.

Finding errors: search and filters

I gave each tool the same question: show me Bob's checkout errors in development on release 1.0.0.

In Sentry I typed it:

user.email:bob@example.com environment:development release:monitoring-lab@1.0.0 url:*checkout*

It returned two issues, showing 6 of 15 and 1 of 9 events matching the filter. One query, one result screen.

Airbrake doesn't have typed search syntax. Typing route:/check returned nothing. Instead you build the filter from chips, and there are 27 of them. The chips are good, though. Each suggestion shows "N of M" counts, so picking User carol told me she hit OutOfStock "5 of 16" times and TypeError "4 of 23" times before I even applied the filter.

The suggestion counts were useful before applying any filter. After selecting a user, the results narrowed to that person’s errors, but I still had to combine chips to approximate the multi-field query I ran in Sentry.

Airbrake's Aggregations tab is also deeper than you'd expect. It broke the TypeError group down by user, version, country, URL and more, and the custom aggregation let me chart any field. That's how I proved the merged group: params.breadcrumbs.0.data.coupon showed blank 29, SAVE10 8, BLACKFRIDAY 7 and FREEBOOKS 2.

One Airbrake Hotspots tooltip displayed "undefined saw 2 errors" during testing. I treated this as a UI anomaly rather than a general limitation.

Triage

Triage becomes more important when errors need owners, priorities and release-specific decisions. Airbrake offered a shorter workflow; Sentry offered more ways to manage an issue over time.

Airbrake's Resolve is one click with an Undo toast, and that's the whole flow. There are no options for when it should count as resolved. The bulk bar has one action: Resolve. You can mute, delete and comment, but there's no assignee, no priority, no snooze and no merge.

That simplicity also carries over to the issue list. The bulk action bar offered Resolve, while the individual group page provided comments and a few basic controls. I could not assign a named owner or set priority from this interface.

Sentry's "Resolved In" menu let me pick the next release, the current release 1.0.0, another existing release or a specific commit. Archive had five modes, from "until escalating" to "until this affects an additional" number of users. On top of that you get priority, assignee, subscribe, share, mark reviewed and bookmark. Merge lives in the bulk action bar.

Resolution and archiving serve different purposes here. The resolution menu lets you tie a fix to a release or commit; the archive menu handles noise that should stay out of the active queue until a specific condition changes.

Releases, deploys and regressions

Releases and deploys

Sentry displayed both releases after I set the release value in the SDK. When I restarted the app with version 1.1.0, a new row showed up on the Releases page within seconds, and I never ran a deploy command. After the 1.1.0 traffic, the list put the two versions side by side: 1.0.0 at a 90.364% crash-free session rate with 90 crashes and 6 new issues, and 1.1.0 at 90% with 31 crashes and 0 new issues. That zero is correct. I didn't ship a new bug in 1.1.0, I just shipped the same broken code again.

The 1.1.0 release page breaks the issues into tabs, "All Issues 6, New Issues 0, Unhandled 4, Regressed 1, Resolved 0", and lists the failing transactions for that release: 30 failures on POST /checkout, 14 on GET /books/:id and 12 on GET /prices/:id. Commits and Files Changed both read 0, because I hadn't connected a repository, and "Last Deploy" stayed empty because I never sent one.

The release overview summarized overall crash-free activity, but the Regressed tab answered a more actionable question: which previously resolved issue had returned in this version? In my test, that list contained the coupon issue only.

Airbrake treats deploys as an event you send. You call its CLI or API after you ship. Until you do, the Deploys page is an empty state. After my 1.1.0 run, both deploys appeared, but the deploy detail said "Nothing to compare" and the Fixed and Introduced counts both read 0.

Sending the deploy event populated Airbrake’s deployment history, but the detail view still showed no useful fixed-versus-introduced comparison for this run. That is different from having no deploy recorded at all.

Regressions

I ran the same experiment in both tools: resolve the bad coupon bug on 1.0.0, ship 1.1.0 without fixing it, and send the same traffic.

In Sentry, the coupon issue reopened on its own. The header changed to "Unhandled | Regressed", the list row got a "Regressed" trend label, and Activity recorded "Regressed in 1.1.0" directly above my "Resolved" entry. The release tag split showed exactly where the events came from: 21 on 1.0.0 and 9 on 1.1.0. The other five issues, which I'd left unresolved, stayed as they were and didn't produce any noise.

The issue activity recorded the regression explicitly. The release breakdown then gave me a way to check its history: 21 events belonged to version 1.0.0 and nine to 1.1.0, all within one issue.

Airbrake's regression story is where my test got messy. "Resolve all errors in environment after a deploy" is on by default. When I sent the 1.1.0 deploy, Activity said it was "resolving 4 errors". Every one of them came back within minutes, because none of the bugs were fixed. All five groups reopened as the unfixed errors arrived again. That made it harder to distinguish my deliberately tested regression from the other known failures.

The reopened group looked like every other row. No "regressed" label, no regression filter and no Activity entry for the reopen. The only hint was the occurrence count: "46 (23 since last deploy)". And because the two TypeErrors were merged, I still couldn't tell which bug had come back without going to Aggregations again.

The setting explains why the next deploy created so much churn: Airbrake resolved groups automatically, then incoming events reopened them. The group row exposed the newer occurrence count, but it did not highlight the returned bug as a separate regression.

Airbrake setting to review: The automatic resolution of errors after deploys was enabled in my project. Decide whether that behavior matches your release workflow. If you deploy frequently without fixing every known issue, disabling it may give you a cleaner regression signal.

I ran the same regression test against Better Stack. After 1.1.0, only the coupon error changed status, to "Reoccurred", and the other five stayed untouched, with 0 new errors on the release. Then I asked AI SRE to reconcile the release: it matched 50 exceptions against 55 failed-request log lines, named the two errors that lost events, and confirmed the coupon bug was the only one that came back.

Track releases and regressions in Better Stack

Performance and tracing

Both products surfaced slow endpoints. Only one gave me a detailed request-by-request path through the work.

Airbrake's Performance page needed no setup beyond the middleware. After the first phase it showed Apdex 0.92, 270 requests, a mean response time of 239.04 ms and an error rate of 10%. The Routes table flagged /search and /prices/:id in orange at the top.

The account-level summary told me the application had slow requests. The route table made that actionable enough for initial triage by ranking endpoints and showing p50 and p95 latency, even though it did not expose a trace of an individual request.

Sentry's trace explorer gave me p95 by endpoint after the third run:

Do not treat these as head-to-head latency scores. The measurement windows differed and the upstream deliberately had randomized delay. The table compares the diagnostic information each interface exposed, not which vendor reports the most accurate p95.

The difference is what happens when you click a slow route. In Airbrake, the /search detail page showed a dash for response time, "0 Queries", and "No data for the chosen time period". There's no per-request trace and no breakdown of where the two seconds went. Queries and Jobs were empty for the whole test.

In Sentry, I clicked into a /search trace and got a 1.99 s waterfall with four spans. The database span, "SELECT books matching search", took 0.23 ms. So the time wasn't in the query, it was in the code around it. For /prices, the http.client span took 3.54 s and showed "HTTP 503", which pointed straight at the upstream.

The first waterfall ruled out the tiny database span as the reason search took roughly two seconds. The second traced a different delay: the outbound price-service call occupied most of the request and returned HTTP 503.

The same Sentry spans landed in Better Stack as traces, and the /prices failure read as one story across both services. The trace flagged a failed span with HTTP 502, then showed the API's outbound http.client call and the price service's own 2.35 s server span nested under it. From any error, "View spans" opens the request's trace directly.

Explore traces in Better Stack

Two quirks. Airbrake's Apdex read 0.82 on the account dashboard and 0.92 on the project page for the same window. Sentry's Backend Overview showed Users 0 on every row, even though most requests had a user set. And Sentry didn't raise a performance issue for either slow route, which I half expected it to.

Profiling

Airbrake doesn't have profiling, so this section is all Sentry.

With @sentry/profiling-node running, the /search profile pointed at one anonymous function at server.js:98:20 that took 1.91 s, 96.23% of the request. That's the CPU-heavy match I planted. The sales report profile showed buildReport at 882 ms, 98.7% of the run.

The search profile isolated the CPU-heavy matching function. A separate profile for the background job surfaced buildReport as its dominant frame, showing that profiling was useful outside normal HTTP requests too.

The path to get there wasn't smooth. The Profiles tab on the transaction summary said "No profiles detected", and the profile icon there opened nothing. I had to go through the trace's own Profiles tab. The Slowest Functions view at 30 days listed buildReport, withSpan and log, and the aggregate flamegraph covered 185 profiles.

That navigation inconsistency matters when you are investigating under pressure. The transaction summary looked empty, but the profile explorer still contained useful samples and aggregated the slowest functions across the test window.

If your slow routes are CPU-bound, this is the feature that tells you which line to fix. In this configuration, Airbrake told me which route was slow; Sentry helped locate the expensive function within that request.

Logs and metrics

In the product experience I tested, Airbrake did not provide comparable structured log or application-metrics explorers. You would need another tool for those investigations.

If you pick Airbrake, logs need a second tool. In Better Stack, my app logs went to the same place as the errors and traces, so "order placed" and "GET /books/404 failed" lines sat a click away from the exceptions they explain.

Search your logs next to your errors

Sentry's Logs explorer held 103 logs from my window, including 61 "order placed" and 12 "POST /checkout failed". Each log carried attributes like total, bookId, orderId and email, plus a link to its trace. Filtering for Bob's orders over $50 returned 7 matches, but only once I used tags[total,number]:>50. A plain total:>50 returned nothing, which tripped me up.

The first view helped me verify message volume. The second shows why structured fields matter: filtering on the numeric total attribute isolated the higher-value orders, provided I used Sentry’s typed attribute syntax.

Metrics worked for business numbers too. I sent checkout.orders as a counter and checkout.revenue as a distribution. Grouping revenue by coupon gave me none 2,652.89, SAVE10 442.79 and HALFOFF 118.99.

Alerts and integrations

Sentry's alert builder has issue alerts with 6 triggers, 15 filters and throttling, plus monitors for metrics, crons, uptime and mobile builds. I created one alert for the UpstreamError and it fired twice during the test.

The rule builder reads like a sentence: when an event comes in, if the issue has more than 5 events in 5 minutes and the exception type is UpstreamError, email me.

Airbrake has email toggles and integrations, not a rule builder. Email options cover digests, an "inbox saver" and a high-volume flag. There's no performance or Apdex alert. The UI has no notification log either, so the only way to confirm an alert went out is to check your inbox.

Airbrake's Jira integration has a nice touch: it can auto-create a ticket on a new error and reopen it if a resolved error comes back.

Both tools end an alert at an inbox or a third-party pager. Better Stack builds alerts on any log or trace query, with thresholds or anomaly detection, and routes them to on-call teams by call, SMS, push or email, so an UpstreamError spike opens an incident instead of another email.

Set up on-call and incident management

AI

Sentry presented Seer as an AI-assisted root-cause and fix workflow, but my account required a connected GitHub or GitLab repository for the action I tried. I did not connect one or run a Seer investigation. Its accuracy and usefulness are therefore not tested here. I found no comparable AI-assisted root-cause workflow in the Airbrake interface tested. This is a comparison of what I could access, not a full audit of future or private features.

Seer stopped at the repository prompt. Better Stack's AI prompt tab didn't need one. On the coupon error it generated a ready-made prompt for Claude Code, Cursor or Codex, plus a plain-language explanation that pointed at line 81 and noticed the request used save10, which isn't a key in COUPONS.

Debug errors with your coding agent

Pricing and quotas

Pricing deserves a separate evaluation from features. In particular, an introductory plan price is not necessarily the full bill once you specify team access, error volumes, retention and performance-event quotas.

Airbrake: verify the package and the event quota

Airbrake's public pricing page currently displays Dev starting at $19/month, Basic at $38/month and Pro at $76/month when billed monthly. It also advertises annual starting prices of $17, $34 and $68/month, respectively, paid annually. The service describes feature packages and monitoring quotas separately, and its pricing page mixes package descriptions with detailed error and APM billing. Confirm the final checkout total for your intended combination rather than adding these prices together without checking.

The account I tested displayed a different mix of plan values, including a $57 Pro-related amount. Because its public Pro starting price was $76, I would not publish the in-app figure as a universal Pro price. The screenshots below document the discrepancy.

The pricing picker shows the packages that appeared in my account. The audit-log screen provides a concrete example of a capability restricted by plan, which matters more than treating every listed feature as included at the entry price.

Sentry: separate subscription price from data volume

Sentry's onboarding showed a 14-day Business trial with no card required in my flow. Its trial screen advertised fallback monthly volumes of 5,000 errors, 5 GB of logs, 5 million spans and 5 GB of metrics. Those were onboarding claims in the tested account, not a substitute for the current subscription agreement.

Sentry's May 2026 pricing example for Stripe Projects lists Developer at free, Team at $29/month and Business at $89/month. Because that page describes a specific purchasing channel, verify the latest direct-subscription terms and included usage at Sentry pricing before using those figures as a direct quote for every buyer.

Cost comparison that actually matters: Estimate errors and spans over a month, decide how long you need to retain them, then check the expected cost after the trial. Sentry's broader diagnostics can reduce time spent investigating, but extra signals may add spend. Airbrake's narrower scope may simplify your bill, but using another log or tracing platform changes the total cost of ownership.

What each tool got right and wrong

Sentry

Airbrake

Which one should you pick?

Choose Airbrake if you have a small backend, one or two people on call, and you mainly want to know that something broke and how often. It gave me route summaries quickly and counted each occurrence in my tested bursts, without needing additional performance instrumentation. Turn off deploy auto-resolve, keep an eye on grouping, and it'll serve you fine.

Choose Sentry if you need to know why something broke without leaving the tool. The stack trace with source, the breadcrumb timeline, the trace waterfall and the profile took me from "/search is slow" to "line 98 is the problem" in a few clicks. That convenience comes with more configuration and a busier interface. You should also validate event counts against application-side telemetry, particularly during bursts.

What changes if you use Python, Ruby, Go or Java?

The main test above used Node.js 11.8.0 of the Sentry SDK and Airbrake Node notifier 2.1.9. Error grouping and issue interfaces are server-side experiences, but what reaches those interfaces depends on language-specific exception metadata, context capture and middleware.

The findings most likely to generalize are the differences I directly observed in the web interfaces: Sentry's issue ownership controls, Airbrake's filter chips, the available trace explorer, and the deployment screens. Do not assume the Node SDK's breadcrumbs, automatic tracing, profiling integrations or event-discard behavior carry over unchanged to other runtimes. Check each vendor's current SDK documentation, then repeat at least the two same-line bugs and one slow-request investigation in your own language.

Before you commit to either tool

Use these five checks in a short trial:

1. Create two different errors with the same top stack frame. Verify that the issue inbox helps rather than hides distinct fixes.
2. Generate repeat failures in a burst. Compare application logs with accepted events and inspect discard or rate-limit counters.
3. Follow one slow request. Check whether you can identify the slow downstream call or CPU function, not just the slow URL.
4. Resolve one bug and deploy it again unfixed. Inspect how regressions appear without creating noise from unrelated issues.
5. Price a realistic month. Include ingestion, retention, teammates, performance data and any separate observability tools.

Final thoughts

The decisive difference in this test was how much work remained after an error notification. Airbrake gave me a compact inbox and useful route-level context, but I had to investigate the combined TypeError group myself. Sentry took me from an issue to surrounding logs, a trace and even a CPU hotspot, though some duplicate events never reached its issue counts.

Two bugs, one line, one misleading group. That was the finding that changed my recommendation. Choose the tool whose defaults help your team see the right problem, then verify those defaults with failures that look like your own production traffic.
