Can ObserveOne replace Mabl and Bugsnag?

No. It does a different job. Error trackers tell you an exception fired. They can't see the failures that never throw: a checkout that silently breaks, an expired SSL certificate, a page that returns 200 and renders blank. ObserveOne monitors those user-facing journeys in production; teams run it alongside an error tracker, not instead of one.
