Because of this, I started building this tool, which will connect to a database instance and diagram it when provided with the necessary information.
Currently supporting PostgreSQL and SQLite with plans to keep building, but I wanted to see what people think.
It can run with just a config file or prompt for the information it needs.
The project can be downloaded on homebrew and the code can be found here: https://github.com/jamesdaniel3/auto-db-diagram
Would love to get any feedback that people have, and bug reports and PRs are welcome!
