Supabase vs PlanetScale: Managed Databases Compared (2026)
Supabase vs PlanetScale is a comparison between a backend platform and a database company. Supabase gives you Postgres plus auth, storage, realtime, edge functions, and vector search in one project. PlanetScale offers high-performance managed databases, originally MySQL on Vitess and now Postgres as well, with branching and deploy requests for schema changes.
Supabase suits teams that want a full backend quickly and a generous free tier. PlanetScale suits teams that care most about database performance, reliability, and safe schema changes at scale, and are fine paying from day one, since it dropped its free Hobby tier in 2024.

Supabase
Supabase is an open-source backend platform built on Postgres. Each project includes a dedicated Postgres database, auto-generated APIs, auth with many providers, row-level security, file storage, realtime subscriptions, edge functions, and vector support via pgvector. Supabase offers database branching for previews, and can be self-hosted or used as a managed service.
PlanetScale
PlanetScale is a managed database platform. Its MySQL offering runs on Vitess, the sharding system created at YouTube, and it now also offers managed Postgres. PlanetScale is known for database branching, deploy requests that review and apply schema changes without downtime, query insights, and high-performance infrastructure. It focuses on the database rather than auth, storage, or functions.

|---|---|---|
| Scope | Full backend: database, auth, storage, realtime, functions. | Database only, focused on performance and operations. |
| Database engine | Postgres. | MySQL on Vitess, plus Postgres. |
| Schema changes | Migrations and branching for previews. | Core strength. Branching and deploy requests without downtime. |
| Scaling | Vertical scaling and read replicas. | Horizontal sharding with Vitess for MySQL. |
| Auth and storage | Built in. | Not included; use other services. |
| Free tier | Yes, with pausing after inactivity. | No. Free Hobby tier removed in 2024. |
| Pricing model | Free tier; paid per organisation plus usage. | Paid plans by cluster size and usage. |
Supabase pros
Complete backend in one platform
Generous free tier
Open source and self-hostable
Postgres ecosystem, including pgvector
Supabase cons
Database performance tuning needs attention at scale
Row-level security takes care to get right
Platform breadth means more to learn
Free projects pause after inactivity
Pricing: Free tier with a limited number of projects that pause after inactivity. Paid plans priced per organisation with included usage, plus usage-based billing for compute, storage, and bandwidth.
PlanetScale pros
Strong database performance and reliability
Safe schema changes with deploy requests
Horizontal scaling for MySQL via Vitess
Useful query insights
PlanetScale cons
No free tier
No built-in auth, storage, or functions
Vitess MySQL has some compatibility limits, such as historically limited foreign key support
More database than a small prototype needs
Pricing: No free tier since 2024. Paid plans priced by cluster size and usage for MySQL and Postgres, with custom plans for large deployments.
Choose Supabase if you need
- - You want auth, storage, and a database in one place
- - You're prototyping or early and want a free tier
- - You need pgvector or the Postgres ecosystem
- - Open source and self-hosting matter
Choose PlanetScale if you need
- - Database performance and uptime are critical
- - You make frequent schema changes and want them safe
- - You need horizontal scaling for MySQL
- - You already have auth and storage elsewhere
How Vantage fits in
Database choices shape what's easy to build, but every feature still needs a clear spec. Vantage gives PMs that workflow: collect context, query the codebase via GitHub to understand the data model, generate the PRD, and push dependency-aware tickets to Linear or Jira. Tickets that call out schema changes up front help engineers plan migrations, whether they run through Supabase or PlanetScale.
