Supabase is an open source backend platform built on PostgreSQL. It presents itself as an open alternative to Google’s Firebase and bundles a database, authentication, file storage, serverless functions and real time features behind simple developer tools.
What it is
Developers create a project and get a Postgres database with automatic APIs, user sign in and storage. Because the core is open source, teams can also host it themselves. The company makes money from hosted usage and describes a path to revenue based on infrastructure use.
History
Paul Copplestone and Ant Wilson founded the company in 2020, according to Sacra. In May 2022 it announced an 80 million dollar Series B led by Felicis Ventures, bringing its total funding to 116 million dollars. TechCrunch reported more than 80,000 developers and over 100,000 databases at that point, with growth that was mostly organic.
Sacra reports a further round of about 80 million dollars in September 2024, a round of more than 100 million dollars led by Accel in March 2025 at roughly a 2 billion dollar valuation, and a 500 million dollar Series F in June 2026 at a 10.5 billion dollar valuation. These are third party reports.
Why it matters to founders
Supabase became a default backend for many small teams and for products built with AI coding tools, which makes it relevant for anyone building a product quickly. See Vibe coding.
