Im looking for some form of self hosted application, ideally dockerized(able), that can connect to and manage an existing database (Im not picky on the DB type, Postgres prolly best though).

However Id like if it manages it via a nice well designed ERD. The closest I have found so far is PgAdmin but unfortunately it’s ERD leaves a lot to be desired. It’s kinda clunky, and it cant “diff” against your existing database to produce a migration script, all it can do is produce a script that expects you to totally drop the existing DB and re-apply the schema from scratch.

Something like Luna/Moon would be cool, but every example I look up seems to be an application you install locally on your machine and interact with directly, as opposed to a web interface.

If you know of such a tool let me know!
