Build once. Query anywhere.

FumaDB unifies access to different databases & ORMs with a single, elegant interface managed with a single schema.

ORM & Database Agnostic
Integrates with multiple ORMs and databases, without worrying about inconsistencies.
Unified Query API
One set of methods to query, mutate, transact regardless of the underlying database or storage.
Unified Schema API
A simple API for version control & schema definition, backward compatible by default without ambiguity.
Pluggable Adapters
Bring your own adapters, or use our maintained adapters for Kysely, Drizzle ORM, Kysely ORM and more.
Built-in Database Migrator
Your library queries in a controlled environment identical to schema, without chaos.
Safe by Default
Type-safe interfaces, schema-aware operations, and robust runtime checks to prevent foot-guns.

Designed for Everyone.

FumaDB gives your library a consistent way to interact with databases.

It’s great for frameworks & SDKs that want integrating database functionality.
