Kolaybase vs. Appwrite: PostgreSQL-Native or Abstracted Backend?
Kolaybase and Appwrite are both self-hostable backend platforms offering authentication, storage, and a database. The biggest difference is the database layer: Kolaybase gives you standard PostgreSQL with full SQL access, while Appwrite provides its own database abstraction.
How Kolaybase is different
Kolaybase is PostgreSQL-native: you write real SQL, use row-level security, and keep full portability via pg_dump. Appwrite offers a polished cross-platform SDK suite and its own collections model. If direct SQL, relational power, and Postgres portability matter most, Kolaybase fits; if you want Appwrite's broad SDK ecosystem and document-style collections, that's its strength.
Feature comparison
| Feature | Kolaybase | Appwrite |
|---|---|---|
| Database | Standard PostgreSQL, full SQL | Abstracted collections (over MariaDB) |
| Direct SQL access | Yes | Limited; via the collections API |
| Auto REST API | PostgREST-style from your schema | REST/GraphQL via SDK |
| Authentication | Keycloak realm per project | Built-in auth + OAuth providers |
| Self-hosting | Docker Compose | Docker (open source) |
| Portability | Standard SQL, pg_dump | Appwrite-specific data model |
Frequently asked questions
- Is Kolaybase an Appwrite alternative?
- Yes. Both are open, self-hostable backends with auth, storage, and databases. The deciding factor is usually whether you want PostgreSQL-native SQL (Kolaybase) or Appwrite's collections model and SDK ecosystem.
- Can I use raw SQL with Kolaybase but not Appwrite?
- Kolaybase exposes standard PostgreSQL, so you write SQL directly and use features like joins, transactions, and row-level security. Appwrite works through its own database API rather than raw SQL.
