An error alert is the start of debugging, not the end
Airbrake's backtrace feature shows you what's breaking and where, and breadcrumbs give you a snapshot of events leading up to the error. But once you have the trace, you still can't see the surrounding logs, the DB query that preceded it, or what the end-user's browser was doing. Atatus correlates all of this automatically — error, trace, log, and user session in a single view, so your team debugs in one place.
