Sentry
Error tracking and performance monitoring.
Application monitoring platform that captures errors, performance issues, and crashes with full context.
About Sentry
Sentry is the leading error tracking and application monitoring tool for developers. It captures exceptions and crashes from web, mobile, and backend applications with full context — the stack trace, the user's session, the breadcrumb trail of events leading to the error, and the exact code line.
Sentry integrates with every major language and framework: JavaScript, Python, Ruby, PHP, Go, Java, Kotlin, Swift, Flutter, and more. The Release Tracking feature lets you see error rates before and after deploys. Performance Monitoring tracks transaction durations, database queries, and frontend Web Vitals.
Source maps support means you see original TypeScript code in error reports, not minified bundles. Sentry automatically groups similar errors, de-duplicates them, and assigns them to the responsible team member via Git blame. For any production application, Sentry is essential for knowing when things break.
