Which BaaS works best for “Vibe Coding” projects — local-first, fast to deploy, and low-cost?

Hey everyone

I’m exploring different Backend-as-a-Service (BaaS) options for “vibe coding” projects — small but creative builds that start locally and later go live (think quick prototypes, coding agents, or AI-powered hobby apps).

I’d love to hear your thoughts on:

• how easy is it to debug or simulate the backend locally?

• how smooth is it to go from local to hosted?

• any “gotchas” or scale-to-zero tricks to keep costs minimal?

• functions, auth, storage, DB branching, edge runtimes, etc.

So far, I’ve been comparing Firebase, Supabase, and PocketBase, but I’d love to know:

• What else should be on the radar?

• Any personal experiences (good or bad) with BaaS that felt perfect for small but scalable projects?

Would love to build a thread of real-world insights and trade-offs!
