## What it is
Measure is an open-source mobile app monitoring and crash reporting platform, positioned as a self-hostable alternative to Firebase Crashlytics. It provides SDKs for Android, iOS, Flutter, React Native, and Kotlin Multiplatform, plus a dashboard for session replays, crash/ANR tracking, performance traces, bug reports, and network monitoring.

## Use cases
- monitor crashes and ANRs in my mobile app
- self-host an alternative to Firebase Crashlytics
- record session replays to debug production bugs
- track app performance and launch times
- capture bug reports when users shake their device
- monitor network request latency and errors in mobile apps
- visualize user journeys through my app screens

## When to choose
- you need mobile-first crash and performance monitoring with full control via self-hosting
- your app spans Android, iOS, Flutter, React Native, or Kotlin Multiplatform and you want one unified dashboard
- you want session replays and bug reports without per-seat pricing

## When to avoid
- you need backend or web frontend observability - Measure is mobile-only
- you prefer a fully managed zero-ops solution and don't want to run Measure Cloud or self-host
- you need deep native desktop or embedded device monitoring

## Facets
- artifact type: service
- maturity: active
- function: monitoring, alerting, tracing, logging, analytics
- domain: mobile-development, monitoring, developer-tools, self-hosted
- platform: cross-platform, self-hosted
