Sentry is an error-monitoring and tracing platform built for developers, with per-event pricing and session replay capped at 50 replays on its paid plans. Shakebug is a mobile-first alternative: shake-to-report bug capture, uncapped session replay, crash AI grouping, and product analytics in one SDK across iOS, Android, Flutter, React Native, and web, on flat plans of $0, $75, and $125 a month.
Worth stating plainly. Sentry is one of the best error-monitoring and tracing tools available, it has a generous free tier for solo devs, and its stack-trace debugging is deep. If your primary need is catching exceptions across a backend and frontend and tracing them to a line of code, Sentry is a strong choice and this page won’t pretend otherwise.
But “error monitoring for developers” and “app quality for a mobile team” are different jobs. If you’re shipping a mobile app and your real questions are why did this user hit a broken screen, what did they do before it crashed, and is this hurting retention — Sentry answers those partially, at a price that scales with event volume.
These are from Sentry’s own live pricing and product pages (sentry.io, June 2026):
Session replay is capped at 50 replays. On Free, Team ($26/mo), and Business ($80/mo) alike. Uncapped replay only comes with custom Enterprise pricing. For a mobile team that wants to watch what users actually did, 50 replays runs out fast.
Pricing is per-event and metered. Plans include a quota (50k errors on paid tiers) and bill pay-as-you-go above it — errors, logs, spans, profiling hours all metered separately. Your bill moves with your traffic, which makes it hard to predict as you grow.
AI debugging is a paid add-on. Sentry’s Seer AI agent is $40 per active contributor per month on top of your plan, not included.
It’s error-stack-first, not user-context-first. Sentry shows you the exception and the trace. It’s not built around an in-app bug report a tester or end user files with an annotated screen, screen recording, and device data attached.
No built-in product analytics. Sentry tells you what broke. It doesn’t tell you your DAU/MAU, weekly cohort retention, or whether a quality issue moved your numbers.
None of this makes Sentry bad. It makes it a developer error-monitoring tool rather than a mobile app-quality tool. The question is which job you’re hiring for.
Shakebug is built around the mobile team’s workflow, not the exception stack — bug capture, replay, crashes and product analytics in one SDK.
Where Sentry meters replay and stops you at 50, Shakebug records the session journey behind every bug and crash on all paid plans — including anonymous, no-login users tracked by device, and identified users tied together by name or email once your SDK sets a user ID. You watch what actually happened, you don’t ration it.
An exception tracker only sees code that threw. Shakebug lets a tester or user shake the device, annotate the screen, and file a report that arrives with a screenshot, screen recording, network and console logs, device model, OS version and app version attached — so the visual bugs, broken flows and wrong-data reports that never raise an exception still reach you with full repro context, not a vague Slack message.
Shakebug also captures crashes automatically and clusters duplicate stack traces with Crash AI — no separate AI add-on fee, unlike Sentry’s Seer — and brings product analytics and retention (sessions, MAU/DAU, stickiness, weekly cohorts) into the same dashboard, all on flat, published pricing instead of a per-event meter.
Sentry is a developer error-monitoring platform; Shakebug is a mobile app-quality SDK. Side by side:
| Sentry | Shakebug | |
|---|---|---|
| Primary job | Error monitoring + tracing (dev-centric) | Mobile app quality + product analytics |
| In-app bug reporting | No (error capture, not user reports) | Yes (shake to report) |
| Session replay | Capped at 50 (Enterprise for more) | Yes, on paid plans |
| Crash grouping | Yes | Yes (Crash AI) |
| AI debugging | Add-on, $40/contributor/mo | Crash AI included |
| Product analytics / retention | No | Yes, built in |
| Pricing model | Per-event, metered | Flat: $0 / $75 / $125 |
| Platforms | Many SDKs (backend + frontend) | iOS, Android, Flutter, React Native, web |
(Sentry figures: sentry.io/pricing, June 2026.)
Keep Sentry if your core need is backend + frontend error monitoring and tracing, your team lives in stack traces, and you want one tool spanning server and client errors. It’s very good at that.
Choose Shakebug if you’re a mobile team that needs testers and users to report bugs with full context, wants session replay without a 50-cap, and wants quality and product analytics on one predictable bill. See how Shakebug works end to end. Many teams run both — Sentry for backend errors, Shakebug for mobile app quality.

Yes, for mobile teams specifically. Sentry is error-monitoring first; Shakebug is built around mobile app quality — shake-to-report bug capture, session replay, crash AI grouping, and product analytics in one SDK for iOS, Android, Flutter, React Native, and web.
Sentry has a free Developer plan, then Team at $26/month and Business at $80/month, with Enterprise custom-priced. Pricing is per-event and metered above each plan's quota, and AI debugging (Seer) is a $40/contributor/month add-on. (sentry.io/pricing, June 2026.)
Yes. Session replay is capped at 50 replays on Sentry's Free, Team, and Business plans. Uncapped replay requires custom Enterprise pricing.
Shakebug uses flat pricing ($0, $75, $125/month) instead of per-event metering, so the cost is predictable as you scale. Sentry's bill rises with event volume. Which is cheaper depends on your traffic, but Shakebug is easier to forecast.
Yes. Many teams keep Sentry for backend error monitoring and use Shakebug for mobile bug reporting, session replay, and product analytics.
