If your app crashes in production and you find out from an App Store review, you need crash reporting. But “crash reporting” now spans a wide range — from a free tool that emails you a stack trace, to full platforms that record the session, capture bug reports, and tie crashes to retention.
This guide compares the main options for mobile teams in 2026 by what they’re actually best at, not by which one we’d like you to pick. Pricing and platform facts below were checked against each vendor’s own pricing page in June 2026. We build one of these tools (Shakebug), and we’ve tried to place it honestly — it wins one category, not all of them.
Quick answer: Crashlytics is the best free crash-only option. Sentry is best if you need backend and frontend error monitoring in one place. Bugsee is strong for video-based bug repro. Instabug (now Luciq) has moved upmarket to enterprise. UXCam is product-analytics-first with crash capture attached. Shakebug is the best all-in-one if you want crash reporting, in-app bug reports, session replay, and product analytics in a single SDK.
Firebase Crashlytics — best free, crash-only option
Crashlytics is the default for a lot of mobile teams, and for good reason: it’s free, Google supports it actively, and in 2026 it added Gemini-powered AI crash insights that explain crashes and suggest fixes. It groups crashes by user impact and monitors release stability in realtime.
What it doesn’t do: in-app bug reporting, session replay, or product analytics. It also covers Android, Apple, Flutter, and Unity — but has no React Native or web SDK. If crash reporting is all you need and you’re on a supported platform, it’s hard to beat at zero cost. If you are looking for a Crashlytics alternative, you will need a third-party SDK.
- Price: Free
- Platforms: Android, Apple, Flutter, Unity
- Best for: Teams who need crash reporting and nothing more
Sentry — best for backend + frontend error monitoring
Sentry is an error-monitoring and tracing platform that spans server and client. Its stack-trace debugging is deep, it has a free Developer tier, and paid plans run $26/month (Team) and $80/month (Business), with Enterprise custom-priced. Its Seer AI debugging agent is a $40-per-contributor-per-month add-on.
Two things mobile teams should know: session replay is capped at 50 replays on every plan below Enterprise, and pricing is per-event and metered, so the bill scales with your traffic. Sentry is excellent at error monitoring; it’s less of a fit if your need is user-reported bugs and replay-heavy mobile QA. For those searching for a Sentry alternative for mobile, client-side visual details are often a priority.
- Price: Free / $26 / $80 / Custom (per-event metered)
- Platforms: Many SDKs, backend and frontend
- Best for: Teams that want one error-monitoring tool across server and client
Bugsee — best for video-based bug repro
Bugsee records video, network, and console logs leading up to a bug or crash, so you see what the user saw. It covers a wide platform range (iOS, Android, React Native, Flutter, Unity, .NET/MAUI) and in 2026 added AI Insights and an MCP server.
Pricing is per unique device: Lite is free (5 devices/month, 3-day retention), Pro is $99/month paid annually ($139 monthly, 50 devices, 30-day retention), and Custom is quote-based. The device-based model is worth modeling against your own usage — it can get expensive for apps on many physical devices. If you need a Bugsee alternative with a simpler pricing structure, flat plans are available.
- Price: Free / $99/mo (annual) / Custom — per device
- Platforms: iOS, Android, React Native, Flutter, Unity, .NET/MAUI
- Best for: Teams who want video reproduction of every bug and crash
Instabug / Luciq — enterprise mobile observability
Instabug rebranded to Luciq in 2026 and repositioned as a mobile observability platform with bug reporting, crash reporting, and APM. It’s a mature product with strong enterprise compliance (SOC 2, SSO/SAML/SCIM).
The catch for smaller teams: Luciq removed all public pricing. The pricing page now lists two enterprise tiers, both gated behind “book a demo” and priced on daily active users plus seats. If you want a known monthly cost without a sales call, that’s a barrier; if you’re an enterprise buyer who needs the compliance depth, it’s built for you. For developers seeking an Instabug/Luciq alternative with self-serve billing, younger SDKs provide faster setups.
- Price: Not public — enterprise “book a demo” only
- Platforms: iOS, Android, and cross-platform frameworks
- Best for: Enterprises needing mobile observability with full compliance
UXCam — best for UX analytics with crash capture
UXCam is a product-analytics platform first — session replay, heatmaps, funnels, retention, and an AI analyst (Tara) — that also captures crashes, UI freezes, and exceptions under its performance monitoring. It’s the right tool if your primary question is how are users behaving rather than what’s crashing.
Pricing isn’t public (Starter/Growth/Enterprise are all “request pricing”), there’s a free plan at 3,000 sessions/month, and Tara AI is a paid add-on. Crash reporting is a feature here, not the focus.
- Price: Not public — free plan at 3,000 sessions/mo; paid plans quote-based
- Platforms: Mobile apps and web
- Best for: Teams who lead with UX analytics and want crash data alongside it
Shakebug — best all-in-one mobile app quality
Shakebug combines the pieces the tools above split up. It does crash reporting with AI grouping, plus shake-to-report in-app bug capture (annotated screenshot, screen recording, network and console logs, device data), session replay, and product analytics (sessions, MAU/DAU, weekly cohort retention, custom events, in-app ratings) — in one SDK across iOS, Android, Flutter, React Native, and web.
Pricing is flat and published: Basic is free (no credit card), Standard is $75/month, Premium is $125/month. The trade-off is maturity — it’s a younger product than Crashlytics or Sentry, and enterprise compliance depth is lighter than Luciq’s. If you want one predictable bill for crash reporting, bug reports, replay, and analytics rather than stitching three tools together, it’s the most complete single option.
- Price: Free / $75 / $125 (flat)
- Platforms: iOS, Android, Flutter, React Native, web
- Best for: Mobile teams who want crash reporting, bug reports, replay, and analytics in one tool
How to choose
Pick by the job you’re actually hiring for:
- Just crashes, free: Crashlytics.
- Server + client error monitoring: Sentry.
- Video repro of every bug: Bugsee.
- Enterprise observability with compliance: Instabug/Luciq.
- UX analytics with crash data attached: UXCam.
- Everything in one SDK on a flat bill: Shakebug.
Most teams start with the free option that fits and add tools as they hit limits. Several of these run fine alongside each other — Sentry for backend errors plus a mobile QA tool, for example.
Frequently asked questions
What is the best free mobile crash reporting tool in 2026?
Firebase Crashlytics is the best free crash-only option — it’s free, actively supported, and now includes AI crash insights. For a free tool that also does bug reporting and analytics, Shakebug has a free plan with no credit card.
What is the best Crashlytics alternative for React Native?
Shakebug, because Crashlytics has no React Native SDK. Shakebug runs one SDK across React Native, iOS, Android, Flutter, and web with crash reporting plus bug capture, session replay, and analytics.
Which crash reporting tool has the most predictable pricing?
Shakebug uses flat published pricing ($0/$75/$125 a month). Sentry is per-event metered, Bugsee is per-device, and Instabug/Luciq and UXCam don’t publish prices, so those bills are harder to forecast.
Do I need a separate analytics tool with my crash reporter?
With Crashlytics, Sentry, or Bugsee, usually yes — they focus on errors and you’d run analytics separately. Shakebug and UXCam include product analytics, though UXCam leads with analytics and Shakebug leads with app quality.
Can I use more than one of these tools together?
Yes. A common setup is Sentry for backend error monitoring plus a mobile-focused tool (like Shakebug or Bugsee) for in-app bug reports and replay. Confirm SDK compatibility on your platform before running two capture SDKs at once.
