Supabase, an open-source Firebase alternative, raises an $80M Series B led by Felicis Ventures and says 80K+ devs have created 100K+ databases on the service
Supabase, which bills itself as an open source alternative to services like Google's Firebase, today announced that it has raised …
Context & Ripple Effects
This round caps a fast climb: Supabase raised a $30M Series A in September 2021 to automate developers' backend work, and just eight months later Felicis is leading an $80M Series B on top of reported traction of 80K+ developers and 100K+ databases created on the service.
The pitch is direct competition with Google's Firebase, but with an open-source core — positioning Supabase as the escape hatch for teams wary of lock-in to a single cloud vendor's backend stack.
First-order effects
- Supabase gets the capital to scale infrastructure and engineering behind its rapidly growing database footprint, while Firebase now faces a funded open-source rival attacking the same developer workflow.
Second-order effects
- Google must defend Firebase against a competitor whose open-source model lowers switching costs, pressuring pricing and feature velocity in the backend-as-a-service market; other vendors automating backend work face the same benchmark.
Third-order effects
- If the pattern holds, open-source alternatives to proprietary cloud services become venture-scale platforms rather than niche projects — a trajectory this coverage later confirms with a $100M Series E at a $5B valuation in October 2025 and then a $500M Series F at a $10B pre-money valuation in June 2026, by which point Supabase is marketing itself as backend tooling for AI apps.
The trend: Backend infrastructure is consolidating around funded open-source challengers that start as vendor lock-in insurance and expand into platform plays riding each new developer wave, from mobile apps to AI apps.
