Crash and error monitoring, compared
There is no ranking on this page.
BugSnag
Error monitoring framed around application stability rather than individual crashes.
Embrace
Real user monitoring for mobile, aimed at problems that never produce a crash log — hangs, slow screens, failed requests.
Emerge Tools
Not a crash reporter: app size analysis, performance testing and build diffing on each pull request.
Firebase Crashlytics
Free crash reporting bundled with Firebase, covering iOS, Android, Flutter and Unity.
Luciq
Bug reporting and in-app user feedback alongside crashes, so a report can come from the person who hit it. Renamed from Instabug.
Sentry
Error tracking and performance monitoring across the whole stack rather than mobile alone, with a self-hostable core.
What you have to check yourself
None of this is knowable from outside, and it is where the decision actually gets made.
- Whether it symbolicates automatically, and what that needs in your build — an unsymbolicated crash report is a stack of addresses.
- What it costs at your event volume rather than your user count. A crash loop in one release is what produces a surprise bill.
- Whether its crash-free rate agrees with Xcode Organizer. The two rarely match, because they count different denominators, and picking one to quote is a decision to make on purpose.
- What the SDK collects, since you declare it on the App Privacy questionnaire as your own collection, not the vendor’s.
- How long history is kept on the plan you would actually be on. Retention is often the limit that matters before volume is.
