I think GlitchTip is still worth packaging alongside Bugsink rather than instead of it.
Bugsink is deliberately errors-only. Sentry self-hosted is unusable at small scale : Kafka, ClickHouse, Snuba. GlitchTip lands in between: clearly more complete than Bugsink (uptime monitoring, performance data, teams/orgs, alert integrations) for a fraction of Sentry's footprint, just Django + PostgreSQL + Redis + a Celery worker.
MIT licensed, official Docker images, drop-in compatible with the Sentry SDKs. For a small team it's the right trade-off, and it maps cleanly onto Cloudron's existing addons. Happy to help test a package.
