Supabase
An open-source Firebase alternative that gives you a Postgres database, auth, storage, and real-time out of the box.
The Full Picture
Supabase has become the default backend for vibe coders. It provides a full Postgres database with a dashboard, authentication (email, OAuth, magic links), file storage, edge functions, and real-time subscriptions. The generous free tier and excellent DX make it the most popular choice for AI-generated apps.
Tools like Lovable and Bolt default to Supabase. The main risk: AI tools sometimes set up overly permissive Row Level Security (RLS) policies, leaving your data exposed.
