Firebase Crashlytics
Overview
What Firebase Crashlytics Is
Firebase Crashlytics is a free, real-time crash reporting tool from Google, part of the Firebase platform. It automatically detects app crashes and non-fatal errors on iOS, Android, Flutter, and Unity apps, then reports them so teams can see stability problems as they happen in the wild rather than waiting for user complaints.
How It Works
Rather than listing every crash, Crashlytics groups them into issues by shared root cause and ranks them by how many users and sessions they affect, so teams fix the highest-impact bugs first. Each issue includes detailed stack traces, device and OS breakdowns, and custom logs and keys. Velocity alerts flag sudden spikes and new regressions.
Why It Matters for Your Business
App stability drives ratings, retention, and revenue, and Crashlytics turns raw crashes into a prioritized fix list backed by real user impact. Our in-house team relies on it during app maintenance and support and across Flutter app development projects to catch regressions early, triage by severity, and keep production apps healthy.
