Supabase vs PlanetScale
Compare Supabase and PlanetScale side by side. Features, pricing, pros and cons to help you choose the right database platform.
🏆 Quick Verdict
Both are modern managed databases, but Supabase is PostgreSQL with extras (Auth, APIs, Storage), while PlanetScale is MySQL with a developer-first schema branching workflow. The choice often comes down to SQL dialect preference and what auxiliary features you need.

In-Depth Analysis
Supabase's competitive advantage is breadth: it's not just a database, it's a backend platform. Along with Postgres, you get auto-generated REST and GraphQL APIs, Authentication with 20+ social providers, Row Level Security for database-level authorization, file Storage, Edge Functions, and Vector search for AI. Teams who want to minimize backend code surface area benefit from Supabase's integrated approach.
PlanetScale's competitive advantage is depth in one specific area: MySQL database management with a developer workflow. Its branching model (inspired by Git) makes schema changes safe and reviewable — you branch the database, test the migration, and merge with zero downtime. For teams doing frequent schema evolution, this workflow is a meaningful improvement over alternatives.
MySQL vs PostgreSQL: PlanetScale is MySQL-compatible, Supabase is PostgreSQL. This matters for ORMs, tools, and extensions. PostgreSQL's extension ecosystem (pgvector, PostGIS, etc.) is broader. MySQL's replication and read replica model has a longer track record at massive scale (it's what MySQL was originally designed for).
The foreign key constraint difference is noteworthy: PlanetScale doesn't enforce foreign key constraints at the database level (it defers to application-level integrity), while PostgreSQL on Supabase enforces them. For teams coming from strict relational database backgrounds, Supabase's standard Postgres behavior is more familiar.
Who Should Choose What?
Choose Supabase if:
Supabase: Teams who want Postgres + integrated Auth + APIs + Storage as a full managed backend
Choose PlanetScale if:
PlanetScale: MySQL teams who need excellent schema branching workflow and are comfortable with MySQL's model
