Measure: open-source alternative to Firebase, Sentry

About Measure

Measure helps mobile teams monitor and fix crashes, ANRs, bugs and performance problems in their apps. It is presented as an open-source alternative to Firebase Crashlytics, with SDKs for Android, iOS, Flutter and React Native so that teams can collect data from the platforms they ship on.

Features include session replays with automatic tracking of clicks, navigation and network calls, crash and ANR reports with screenshots and stack traces, performance traces and spans, bug reports triggered by a device shake, user journeys, network performance views and an app health dashboard. Adaptive capture lets you change data collection settings without releasing an app update, and a Measure Agent lets you investigate issues in natural language from Slack or a coding agent via MCP.

You can sign up to Measure Cloud or self-host it on your own servers. The project is licensed under Apache-2.0 and has a TypeScript codebase on the dashboard side, with Kotlin, Swift and Dart SDK components. It suits mobile development teams who want crash reporting and observability with the option to keep data on infrastructure they control.
