- Source maps support
- Performance monitoring
- Release tracking
- Generous free tier
Desventajas
- Can be noisy initially
- Costs increase with volume
- Some SDK overhead
- Alert tuning needed
Why Every Application Needs Sentry
Production errors are inevitable. How you handle them matters. Sentry shows you exactly what went wrong, why, and for whom.
My Experience
I add Sentry to every project. The first time an error happens in production, I see the full stack trace, the user’s actions leading up to it, and the context I need to fix it. No more guessing.
What Makes Sentry Essential
-
Error Context - Stack traces with source maps. Breadcrumbs showing user actions. Environment details. Everything you need to reproduce and fix issues.
-
Issue Grouping - Smart grouping of similar errors. See how many users are affected, when it started, which release introduced it. Prioritize based on impact.
-
Performance Monitoring - Transaction tracing shows where time is spent. Identify slow endpoints, database queries, and performance regressions. Connected to your errors.
-
Release Health - Track error rates across releases. Know if a deploy introduced problems. Roll back with confidence when needed.
Where Sentry Falls Short
Can be noisy without proper configuration. Costs increase with error volume (which incentivizes fixing errors). Some SDK overhead in performance-critical applications.
Who Should Use Sentry
- Every web application in production
- Mobile apps needing crash reporting
- Backend services tracking exceptions
- Teams caring about user experience
