Sentry is an application monitoring platform focused on real-time error tracking and performance monitoring that helps development teams catch, diagnose, and fix bugs in production before they impact users. Unlike full-stack observability platforms that monitor infrastructure and networks, Sentry specializes in application-level diagnostics — capturing exceptions with complete stack traces, breadcrumbs showing the sequence of events leading to errors, and user context including device, browser, and session information. Used by over 100,000 organizations processing billions of error events daily, it has become the industry standard for crash reporting across web, mobile, desktop, and backend applications.
The Session Replay feature reconstructs user interactions leading to errors as video-like recordings, showing clicks, scrolls, page navigations, network requests, and console output that eliminate the guesswork of reproducing production issues. Seer, the AI debugging agent, performs automated root cause analysis on captured errors and suggests specific code fixes when connected to GitHub repositories. The platform supports SDKs for over 100 languages and frameworks including JavaScript, Python, Java, Ruby, Go, iOS, Android, React, and Django, with setup typically requiring only a few lines of code.
Pricing follows an event-based model starting with a free Developer tier at 5,000 errors per month, Team at $26 per month with 50,000 errors, and Business at $80 per month with 100,000 errors. Enterprise plans offer custom pricing with advanced security, compliance SLAs, and dedicated support. A self-hosted option allows organizations to run Sentry on their own infrastructure using Docker for complete data sovereignty. Deep integrations with GitHub, GitLab, Jira, Slack, and PagerDuty connect error tracking directly into development workflows for streamlined issue resolution.
