About
Supabase is an open-source Firebase alternative that provides a complete backend platform built on PostgreSQL. It includes a real-time database with row-level security, built-in authentication supporting email/password, OAuth, and magic links, file storage with automatic CDN delivery, and Edge Functions for serverless API endpoints. Unlike Firebase, Supabase uses SQL (Postgres) rather than NoSQL, giving developers the full power of relational queries, joins, and migrations. For AI-powered app development, Supabase is particularly valuable — its Edge Functions can invoke AI APIs (like OpenAI's image generation), its Postgres database handles structured user data and points systems, and its storage bucket serves AI-generated assets. Combined with Expo/React Native for the frontend, Supabase provides the complete backend infrastructure needed to launch an AI app on the App Store.
