We use airbrake with self-hosted errbit (opensource airbrake api-compatible clone) server.
If you already integrated with Airbrake, you just have to reconfigure the host it reports to, to your own errbit server and it'll swap everything over from deploy tracking to error reporting.
Errbit is an active project, https://github.com/errbit/errbit, and error reporting libraries don't tend to need a lot of maintenance.
