Intelligent crash grouping

Prioritize the most harmful bugs first, with tools that help you cut through the noise and discover critical bugs

Reliable, best in class error grouping

Identifying which errors happen most and hurt the most users is powered by BugSnag's intelligent error categorization and grouping. Aggregating errors by root cause decreases noise in your notifications and helps you assess impact.

Powerful filtering and sorting

Find specific errors that need investigating, like those affecting a certain version of your app, or a user reported bug. Filtering updates user and event counts so you can assess impact from a zoomed in view of your crash data.

Know when problems spike

If a backend or API change causes an increase in errors, BugSnag alerts you immediately. The error spiking algorithm uses an exponential moving average to identify anomalies in your error rate.

Benchmark releases

Use the Releases dashboard to decide if a release is successful or needs to be rolled back. The crash rate indicator shows the percentage of sessions in a release that end in a crash, allowing you to compare release health and track improvements over time.
