Founded in 2012 in San Francisco by David Cramer and Chris Jennings, Sentry has raised approximately $217 million and generates significant revenue from its Sentry cloud hosted service, while maintaining an open-source version that has driven massive developer adoption. Sentry's platform captures exceptions and errors in production code with full stack trace, request context, user data, and performance timing — giving engineers the information needed to reproduce and fix bugs that users encounter in production. The platform supports 100+ language and framework integrations (Python, JavaScript, React, Node.js, Java, Ruby, PHP) and can be deployed as self-hosted or as Sentry cloud-managed. In 2025, Sentry has expanded from error tracking into broader performance monitoring — distributed traces, database query performance, frontend core web vitals, and session replay — competing more directly with Datadog and New Relic for application performance monitoring. The company's developer-first pricing (generous free tier for open source and small projects) has driven adoption from individual developers to enterprise engineering teams. Sentry competes with Datadog APM, Rollbar, Bugsnag, and Dynatrace for error monitoring and performance observability. The 2025 strategy focuses on expanding its performance monitoring capabilities, launching AI-assisted issue grouping and resolution recommendations, and growing enterprise contracts through usage-based pricing that scales with engineering team size. ## Frequently Asked Questions ### What is Sentry?
