MVP should be built on things you will use later. Which is C#/Java/Python, React, and Postgres SQL unless your product has unique needs outside of the traditional space (it's a game, ML project, IoT project, mobile-only app, etc). Firebase is too expensive. Only use case if you have only front end devs. Dynomo/Mongo/Cosmos all do the same niche thing - you don't need a no-SQL db for most apps. 4. Apparently a lot of YCombinator companies still use Rails. I don't really understand why. edit: I didn't know about Supabase - thanks.
