Overview
Sentry is an application monitoring platform focused on error tracking and performance monitoring. It captures unhandled exceptions, provides detailed stack traces with source maps, and groups similar errors together for efficient triage.
Beyond error tracking, Sentry provides performance monitoring with distributed tracing, allowing you to see the full journey of a request across frontend, backend, and third-party services. Session replay lets you watch a video-like reconstruction of what the user was doing when an error occurred.
Sentry supports 100+ platforms and frameworks, with deep integrations for React, Next.js, Node.js, Python, and more. It is open-source and can be self-hosted, though most teams use the managed SaaS offering.
When to Use
Use Sentry in every production application for error tracking. It is the industry standard for understanding and fixing errors in production. Add performance monitoring when you need visibility into application performance bottlenecks.
