+1 for Glitchtip.

We also found the same problem as OP with self hosting sentry. Each release would unleash more containers and consume more memory until we couldn't run anything on the 32gb server except Sentry.

We looked at both GlitchTip and BugSink and only settled on GlitchTip as it was maintained by a bigger team. Feature wise they were quite similar and both good alternatives.

So far so good with GlitchTip.

And thanks Op for making BugSink, the more alternatives the better.
