Just as a quick aside, I tried Coolify, Dokploy, Dockge, and Komodo, and if you're trying to do a Heroku-style PaaS, Dokploy is really good. Hands down the best UX for delivering apps & databases. It's too bad about the licensing. (e.g. OIDC + audit logs behind a paid enterprise license.)

Coolify is full of features, but the UX suffers and they had a nasty breaking bug at one point (related to Traefik if you want to search it.) Dockge is just a simple interface into your running Docker containers and Komodo is a bit harder to understand/come up with a viable deployment model, and has no built-in support for things like databases.
