Supabase for Builders
Supabase is an open-source Firebase alternative built on PostgreSQL. It gives you a database, authentication, file storage, edge functions, and realtime subscriptions — all accessible via a clean JavaScript SDK. This course teaches Supabase through building a real product: from creating a project to deploying auth, data, and file uploads.
