Ask HN: What would be your stack if you are building an MVP today?

Specifically the backend. I'd love to hear your reasons. Do you keep one eye on what the stack would be post MVP?

1. Old schoolish (VPS - Maybe DO, Django/Flask/Rails/Remix/Next with postgres)

2. Supabase etc with JS/TS on either side of the network

3. Lambda/Cloud functions with Firebase/Dyanamo DB/Cosmos DB etc

4..n. What else and why?
