🪲Error TrackingAbout Sentry
Sentry is the most widely used error monitoring platform — over 4 million developers trust it to track and fix bugs in production. When an unhandled exception occurs, Sentry captures the full stack trace, user context, environment variables, and the breadcrumbs (events leading up to the error). Errors are automatically grouped into issues so you see '500 occurrences of TypeError: Cannot read property X' rather than 500 separate alerts. Release tracking connects errors to specific deploys, so you instantly know which release introduced a regression. Performance monitoring adds transaction tracing to identify slow database queries and N+1 problems. The free tier handles 5,000 errors/month — enough for most side projects. Paid plans start at $26/month for 50,000 errors. Sentry's SDKs cover 100+ platforms: JavaScript, Python, Go, React Native, iOS, Android, and more. Compare to Bugsnag (better for mobile), Rollbar (similar feature set), LogRocket (adds session replay). Best for: virtually every engineering team building production software — Sentry is the default error monitoring choice.
What's Great
- ✓Industry standard with 4M+ developer users and 100+ SDK integrations
- ✓Intelligent error grouping reduces noise vs raw error logs
- ✓Release tracking immediately identifies which deploy caused regression
- ✓Generous free tier: 5,000 errors/month
- ✓Performance monitoring adds transaction tracing and database query analysis
Watch Out For
- !Can generate alert fatigue on high-traffic apps without proper configuration
- !Session replay features cost extra
- !Self-hosted option requires significant infrastructure management
Common Use Cases
A developer is alerted 3 minutes after deploying to production that a specific error affects 5% of users
A team uses release tracking to identify that a specific commit introduced a regression in the checkout flow
A mobile developer tracks JavaScript errors in a React Native app across iOS and Android
An SRE sets up Sentry performance monitoring to catch slow database queries before they affect users
