Supabase

Supabase is an open source Firebase alternative that helps developers build fast, scalable, and secure backends without the complexity of managing infrastructure. Powered by PostgreSQL, Supabase gives you everything you need to ship your product—from authentication and real-time data to edge functions and file storage—out of the box. At its core, Supabase lets you spin up a fully-managed Postgres database with REST and real-time APIs instantly generated from your schema. It includes a powerful auth system supporting social logins, magic links, and multi-factor authentication. Developers can also take advantage of edge functions (written in TypeScript) to build custom logic close to the user, improving speed and efficiency. Supabase is designed with developers in mind, offering an intuitive dashboard, seamless GitHub integration, and a CLI for managing local development and deployments. It’s SOC2 certified, supports row-level security (RLS) by default, and gives you fine-grained control over roles and access. Whether you're building a SaaS product, mobile app, or MVP, Supabase helps you launch faster without sacrificing flexibility or performance. It’s trusted by startups and indie hackers around the world—and thanks to its open source nature, you can self-host anytime. Supabase is not just an alternative to Firebase—it's a modern backend platform that gives you full control, transparency, and scalability.
