Kolaybase vs. Supabase: Which PostgreSQL Backend Should You Use?
Both Kolaybase and Supabase give you a PostgreSQL database with an auto-generated REST API, authentication, and storage. The differences come down to isolation, self-hosting, and how the platform is operated.
How Kolaybase is different
Kolaybase provisions a dedicated PostgreSQL database and an isolated auth realm per project, and is built to be self-hosted with Docker Compose from day one. If you want true single-tenant isolation and full control of where your data runs, that's the core distinction.
Feature comparison
| Feature | Kolaybase | Supabase |
|---|---|---|
| Database model | Dedicated PostgreSQL database per project | PostgreSQL project (schema-based isolation) |
| Self-hosting | First-class, Docker Compose included | Supported, more involved setup |
| Auto REST API | Yes, PostgREST-style | Yes, PostgREST |
| Authentication | Keycloak realm per project (OAuth + email) | GoTrue (email, OAuth, magic links) |
| Storage | S3-compatible (MinIO) | S3-compatible |
| Query language | Standard SQL, no lock-in | Standard SQL, no lock-in |
| Realtime | Roadmap | Built-in |
Frequently asked questions
- Is Kolaybase a Supabase alternative?
- Yes. Kolaybase offers the same core building blocks — hosted PostgreSQL, an auto-generated REST API, authentication, and object storage — with a per-project dedicated database and a self-hosting-first design.
- Can I migrate from Supabase to Kolaybase?
- Because both are standard PostgreSQL, you can export your schema and data with pg_dump and import it into a Kolaybase project. There is no proprietary query language to rewrite.
- Does Kolaybase have realtime subscriptions?
- Realtime is on the roadmap. Today Kolaybase focuses on database, REST API, auth, and storage. If realtime is a hard requirement right now, factor that into your decision.
