How can I duplicate an existing project to use as a test data base for my dev branch?

Use a migration tool to handle all your database setup and this can be done with less effort.

Hello! I'm unfamiliar with this side of development. Can you name a tool I could use as a research entry point?

I personally use ley. https://github.com/lukeed/ley

You can see it in use with on of my Supabase project's here https://github.com/silentworks/waiting-list

Thank you! I appreciate the help. I'm getting really close to launching my Alpha. Just need to button up the concerns.
