Open-source error tracking that helps developers monitor and fix crashes in real time. Iterate continuously. Boost efficiency. Improve the user experience.

What Does It Offer

Find out about exceptions right away

Set up Sentry in minutes with just a few lines of code. Get notifications via email, SMS, or chat as part of an existing workflow when errors occur or resurface.

Quickly find and fix production errors

Triage, reproduce and resolve errors with max efficiency and visibility. Exception handling with Sentry helps developers build better apps and iterate faster.

See the impact of each release

Integrate error tracking with your commit and deploy workflows. Aggregate events to see where bugs happen, how often, and who are affected before users even notice.

Error tracking built for the community

Sentry started as and remains a 100% open-source project, now delivered as a hosted service. Development aligns to security, observability, and production at scale.

Give users the power to help debug errors

Automatically prompt users for feedback so they know that you know things aren’t working.

Let them know you resolved their issue

Reach out to let affected users know they’ve experienced an error and help is on the way.

Features

If bugs make it to production, jump into action before your users even notice a problem. Your customers (and your workflow) will thank you.

Sentry’s features help you identify and debug errors and give you all the insight to decide when to fix or rollback. When things go to hell, you’ll have help fighting fires. What more?

Error monitoring

  • View actual code in stack traces, with source maps for JS, symbolication for iOS, and stack locals for Python bug tracking.
  • See the error’s parameters and session information in the crash report.
  • Filter noisy stack traces with the app, framework, and raw error views.

Why just debug errors?

Reproduce errors without user feedback. Sentry error monitoring includes each bug’s history of events and actions.

Crash reporting

Understand the context that contributed to errors with tags and relevant information about your software, environment, and users. You can also submit optional custom data to provide extra context for bug tracking that is unique to your application and business.

  • “How many widgets were visible when the app crashed?”
  • “Was their game running in 32 bit or 64-bit mode?”
  • “Which clients’ users are experiencing this bug?”
  • “What was the value of their shopping cart?”
  • “Did the waxing gibbous cause the problem?”

Stay on top of user experience

  • Link commit data to your error monitoring workflow so you can easily determine the cause of a bug and resolve with the release.
  • Track problems by release version so you can focus on debugging live errors and get alerted if things regress in the future.
  • Triage more efficiently by automatically assigning new issues to the author of the commit where the error originated.

Understand the bigger picture

  • Use issue graphs to understand the frequency, scope, and impact of errors and prioritize what needs to be fixed.
  • Get alerts via email, SMS, or chat when bugs make it into production without disrupting your development workflow.
  • Get real-time insight immediately. Setup takes just a few minutes and typically requires only two lines of code.

Ask users for feedback

When frontend errors happen, Sentry can prompt users for feedback so you can compare their experiences to the data.
