Sentry

Sentry is a developer-first monitoring tool that provides visibility into errors, crashes, and performance issues in your software. Whether you're running a React frontend, a mobile app, or a distributed backend system, Sentry captures detailed error logs and performance metrics to help you pinpoint the exact cause of problems—fast. It integrates with most popular frameworks, source control systems like GitHub, and deployment tools so you can trace issues back to specific commits or releases. With rich contextual insights, stack traces, user impact tracking, and customizable alerts, Sentry empowers dev teams to fix bugs before users even notice them and optimize application performance at scale. Key features includes: • Error Monitoring – Catch and resolve runtime errors with detailed stack traces and context • Performance Monitoring – Track app performance, slowdowns, and latency bottlenecks • Release Tracking – Tie errors and issues to specific code deployments or versions • Source Maps & Stack Trace Unminifying – Understand production errors, even in minified code • User Impact Insights – See which users were affected by a bug or slowdown • GitHub/GitLab/Bitbucket Integration – Link errors directly to commits and issues • Custom Alerts & Notifications – Get notified via Slack, email, PagerDuty, or custom channels • Session Replay (optional) – Watch real-time user sessions to visualize how issues happened • Support for All Major Languages & Frameworks – JavaScript, Python, Java, .NET, React, iOS, Android, and more • Open Source Core – Use the self-hosted version or Sentry's managed cloud service From startups to enterprise teams, Sentry is trusted by developers to maintain quality and reliability in production.
