Sentry
Error tracking and performance monitoring for developers
Sentry is profiled here as a Observability tool for engineering teams. Read about features, pricing, and how it compares to related options in the tools directory.
Description
Sentry is an application monitoring service, founded in 2012 by David Cramer and Chris Jennings, that captures errors and performance data so developers can fix problems with full context. When an exception fires, Sentry records the stack trace, request data, and the release and commit that introduced it, then groups similar events so a team triages a small set of distinct issues with the context attached. Its source is available under the Functional Source License, and Sentry offers a free Developer tier for individuals and small projects.
Key Capabilities:
Error tracking with stack traces, breadcrumbs, and request context
Issue grouping that collapses duplicate events into one actionable problem
Release health that ties errors to the commit and deploy that caused them
Performance monitoring and tracing across frontend and backend
Session replay that reconstructs what a user did before an error
SDKs for most major languages and frameworks
