Supabase Review
Complete analysis — features, pros & cons, best use cases, and top alternatives
Overview
Supabase is an open-source Firebase alternative that provides a full Postgres database, authentication, real-time subscriptions, storage, and edge functions. The free tier includes 500 MB database, 50,000 monthly active users, 1 GB file storage, 2 GB bandwidth, and 500K edge function invocations. Supabase's standout feature is real-time subscriptions — database changes are streamed to clients instantly via WebSockets. Row Level Security (RLS) provides fine-grained access control directly at the database level. The auto-generated RESTful and GraphQL APIs eliminate the need for a traditional backend. With a generous free tier, self-hosting option, and growing ecosystem, Supabase has become the default backend for many modern web applications, especially those built with Next.js, SvelteKit, or React Native.
