Comparison
Supabase vs Firebase for Vibe Coders
These are two of the fastest ways to bolt a real backend onto an AI-built app, but they optimize for different futures. Supabase is usually the better default for SQL-first web apps. Firebase is still brutally effective when speed, mobile support, and Google-flavored app tooling matter most.
