Quick Verdict
Choose Supabase if you need a full open-source backend suite with PostgreSQL and real-time features. Choose PlanetScale if you need a highly scalable, serverless MySQL database with a robust Git-like workflow for schema management.
Supabase is an open-source backend-as-a-service built on PostgreSQL, offering built-in auth, real-time subscriptions, and auto-generated APIs, positioning it as a Firebase alternative. PlanetScale is a serverless MySQL-compatible platform built on Vitess, focusing on horizontal scalability and a non-blocking schema change workflow. While Supabase provides a more integrated feature set at a lower entry price, PlanetScale specializes in high-availability database operations for MySQL-centric applications. Their core divergence lies in database engine (Postgres vs. MySQL) and primary value proposition (integrated backend vs. scalable database platform).
