Supabase

Supabase is an open-source backend platform built around a managed Postgres database. It provides similar building blocks to Firebase—such as auth, real-time, and storage—but is SQL-first, self-hostable, and designed to avoid vendor lock-in. You can use standard Postgres tooling and move between self-hosted and cloud deployments as needed.

Supabase offers a generous free tier suitable for prototypes, hobby projects, and small apps. Paid plans are typically based on usage, such as database size, bandwidth, and compute resources. For the latest and detailed pricing information, please refer to the official Supabase website.

You can choose either approach. Supabase is fully open source, so you can self-host the components on your own infrastructure for maximum control. Alternatively, you can use Supabase's managed cloud platform to avoid operating overhead and focus on building your product.

Supabase provides official client libraries for JavaScript and TypeScript, and is commonly used with frameworks like Next.js, React, Svelte, Vue, and Flutter. Because it is built on Postgres, you can also connect from any backend language that supports Postgres, such as Node.js, Python, Go, or Ruby.

Yes. Supabase is designed for production workloads, with features like Row Level Security, backups, and horizontal scaling options. Teams can start small and scale up as traffic and data grow, while keeping the same stack from prototype to enterprise-grade deployment.
