PlanetScale vs Supabase: The Verdict

⚡ Quick Verdict:

Choose PlanetScale for a serverless MySQL database with branching and zero-downtime schema changes. Choose Supabase for a PostgreSQL-based backend with auth, storage, and real-time built in. PlanetScale is the database; Supabase is the backend platform.

PlanetScale and Supabase are both database-as-a-service platforms but they serve different needs. PlanetScale is a serverless MySQL database built on Vitess (YouTube's database technology). Supabase is a Firebase alternative built on PostgreSQL with auth, storage, real-time, and edge functions.

PlanetScale's killer feature is database branching. Create a branch of your database schema, make changes, and merge — like Git for your database. Zero-downtime schema migrations mean you never take your database offline for changes. For teams that deploy frequently, this workflow is transformative.

Supabase offers more than just a database. Auth (email, OAuth, magic links), file storage, real-time subscriptions, edge functions, and a REST/GraphQL API are all included. For frontend developers building full-stack apps, Supabase provides the entire backend. PlanetScale is just the database — you need separate services for auth, storage, and APIs.

The database engine difference matters. PlanetScale uses MySQL (via Vitess). Supabase uses PostgreSQL. PostgreSQL has richer features (JSONB, arrays, full-text search, PostGIS). MySQL is simpler and more widely deployed. Your team's SQL dialect preference may drive the choice.
