Supabase
About
Open-source Firebase alternative — Postgres database, auth, storage, edge functions, and realtime APIs.
What is Supabase?
Supabase is an open-source platform that bundles several backend services around a PostgreSQL database. According to the project’s documentation and repository, it provides authentication, file storage, edge functions, and real-time APIs as integrated modules. The codebase is hosted on GitHub, where it has accumulated 107,108 stars, indicating broad developer interest. The platform describes itself as an alternative to Firebase, but built on Postgres instead of a proprietary NoSQL store. Its core offering is a managed PostgreSQL database with additional features layered on top, such as Row Level Security for fine-grained access control and auto-generated RESTful APIs from the database schema. The real-time capabilities use PostgreSQL’s logical replication to push changes to connected clients. The docs emphasize that all components are open-source, allowing self-hosting or use of the managed cloud service.
Who is Supabase for?
The platform targets developers who want a backend-as-a-service with standard relational database features. It is suited for teams building web or mobile applications that need a Postgres database with minimal operational overhead. The included auth system supports passwordless login, OAuth providers, and multi-factor authentication out of the box. Storage integrates with object storage (S3-compatible), and edge functions allow running TypeScript serverless code close to users. Based on the repository documentation, common use cases include SaaS products, real-time dashboards, and projects that require a single vendor for database, auth, and file handling. Teams that already use Postgres may find the transition straightforward because the schema and queries remain standard SQL. The open-source nature also appeals to organizations that prefer self-hosting for compliance or cost reasons.
How much does Supabase cost?
Supabase operates on a freemium pricing model, with a free tier starting at $0 per month. The pricing page outlines that the free plan includes unlimited API requests, up to 500 MB of database storage, 2 GB of bandwidth, and support for 50,000 monthly active users for auth. Paid plans add larger compute sizes, more storage, higher bandwidth, and priority support. There is no separate charge for the real-time features or edge functions beyond the selected tier’s limits. Because the software is open-source, users who exceed the free tier limits can also self-host the entire stack using their own infrastructure, avoiding per-unit billing. The repository contains deployment scripts for Kubernetes and Docker Compose. The pricing page does not list any per-seat fees or usage surcharges for overages; instead, users must manually upgrade plans or adjust resource allocations. Overall, the cost structure is designed to scale from a zero-cost prototype to a production system with predictable monthly pricing.
