Application monitoring for every developer

Identify, debug, and resolve

Trace errors across your entire stack and act fast with deep context like the line of code, user actions and functions leading up to when it occurred.

Know when your code breaks and who can fix it. See how many users experienced the error, auto-assign issues to the developer who pushed the culprit commit, and alert your team when an error occurs, regresses, or escalates.

Get real-time visibility across releases to see core metrics like crash-free sessions, version adoption, and failure rate so you can see the moment a release starts to degrade and quickly take action.
