Find the exact error you're looking for with precise filtering
Filter crashes by any metric
Filter by any attribute to find the exact errors that matter
Find any specific error, or subset of errors, using filter attributes, like user or environmental diagnostic data.
Bugsnag is the only platform that retains all error data, so you can see precise error and users impacted counts, even after filtering down to a subset of errors.
Track progress on bug fixes in Bugsnag and your issue tracker
Send crashes to issue trackers like Pivotal Tracker
Efficient debugging workflow
Unlike Crashlytics, Bugsnag comes with built-in workflow features that help you streamline your debugging process. And the more efficient you become at debugging, the more time you’ll have to build better features for your users.
Integrate with your issue tracker to better manage bug fixes
Two-way integrations synchronize error status between your tools. Whether you’re in Bugsnag or your issue tracker, know definitively what progress has been made on bug fixes.
Thoughtfully built with mobile applications in mind
Support for dSYMs, Proguard, and Jack
Bugsnag automatically captures a stacktrace for every crash. We support dSYMs for iOS, and Proguard and Jack for Android SDK and NDK, allowing us to map crashes to your source code and build a readable stacktrace.
See user actions leading up to an error
Bugsnag for Cocoa and Android automatically capture breadcrumbs leading up to a crash. Breadcrumbs are a timeline of common user and system actions that can help you reproduce errors and prove you’ve fixed a bug.
