Supabase (PostgreSQL

Supabase is the open-source Firebase alternative that provides a full backend suite built on a dedicated PostgreSQL database.

Supabase delivers a production-ready backend in minutes by wrapping a full PostgreSQL instance with automated tools. You get instant RESTful APIs via PostgREST, real-time subscriptions through Elixir Phoenix, and built-in GoTrue authentication. It handles complex requirements like Row Level Security (RLS) for granular data access and integrates S3-compatible storage for large assets. By using standard SQL instead of proprietary NoSQL, it ensures zero vendor lock-in and supports over 50 PostgreSQL extensions (including pgvector for AI workloads).
