Sentry
Teams who want the deepest error tooling and will pay per event for it
The most capable error monitoring platform available, and the honest first recommendation for most teams leaving Crashlytics for capability reasons. Distributed tracing, session replay video, source map and dSYM symbolication, release health, and SDKs for dozens of languages including your backend. The cost is billing complexity: errors, spans, replays, logs, cron monitors, uptime checks and profiling are each metered separately, so the invoice moves in ways that are hard to forecast.
Strengths
- Best-in-class symbolication, grouping and release health
- Distributed tracing and APM across backend services
- Session replay video, and SDKs for almost any language you run
Trade-offs
- Seven separate meters make the bill genuinely hard to predict
- No product analytics — no funnels, retention or attribution
- Substantially more tool than a small mobile team needs
