Looks great. I would love to see some development tooling (if it's license allows), that I'm currently considering self hosting: Posthog, Sentry and Jitsu (aka EventNative). If Sentry setup is too insane maybe GlitchTip.
I don't know if you run Clickhouse (needed for PostHog) yet, but I bet it will be used by a bunch of self hosted apps in the future and would be worth it.
A very attractive option would be some kind of "Try on PikaPods" button, if you can somehow muster a very limited free tier, that these projects can put on their READMEs. A few have that with heroku and it makes them way more approachable.
The pricing is very attractive compared to running these things e.g. on RDS+Fargate (~25x). Most people would probably run on Digital Ocean or Hetzner Cloud which is closer.
