About Sentry

Sentry is an open-source application monitoring and debugging platform designed to help developers detect, investigate, and resolve errors, crashes, performance bottlenecks, and infrastructure issues across web, mobile, backend, and desktop applications. The platform provides real-time error tracking, distributed tracing, session replay, logs, uptime monitoring, and performance insights through a unified observability interface. Sentry supports dozens of official SDKs including JavaScript, Python, PHP, Go, Rust, Java, .NET, Ruby, Flutter, Swift, Unity, Unreal Engine, and more, making it suitable for cross-platform development teams and large-scale production environments. Built for modern DevOps and software engineering workflows, Sentry integrates with GitHub, GitLab, Slack, Jira, CI/CD pipelines, and cloud infrastructure tools while supporting self-hosted deployments for organizations that require full control over data privacy and infrastructure. The project includes extensive documentation, community discussions, open-source contributions, and a scalable architecture designed for debugging distributed systems, APIs, mobile apps, games, and enterprise software.
