The database that speaks ORM natively

What is ORMDB? ORMDB is an open-source, Rust-native relational database that understands your entities and relations, so a single query returns a whole object graph instead of the N+1 round-trips a traditional ORM generates.

RustTypeScriptPython

ORMDB is an open-source relational database written in Rust that speaks ORM natively. It fetches object graphs in one round-trip, supports native relations, ACID transactions, safe online migrations, change streams (CDC), plus vector, geo, and full-text search. It drops into Prisma, Drizzle, TypeORM, and SQLAlchemy.

Highlights

Graph fetches in a single query
Native one-to-one, one-to-many, many-to-many relations
Safe online migrations with automatic safety grading
Change streams for cache invalidation and real-time
Vector, geo, and full-text search built in
Drop-in adapters for Prisma, Drizzle, TypeORM, SQLAlchemy

How ORMDB works

You declare your model graph — entities, relations, and constraints — and ORMDB stores it as first-class metadata rather than inferring it after the fact. Because the database already knows how User relates to Post relates to Comment, it can plan a single traversal that returns the whole shape you asked for.

When your application requests an object graph, ORMDB resolves it server-side in one round-trip. There is no N+1 explosion and no impedance mismatch to hand-tune, because the join planning happens where the data lives instead of in an application-layer ORM stitching rows together.

On top of the relational core, ORMDB ships ACID transactions, safe online migrations with automatic safety grading, change streams (CDC) for cache invalidation and real-time features, and built-in vector, geo, and full-text search — so AI features like semantic search sit next to your relational data instead of in a separate system.

Example

// Fetch a full object graph in one round-trip — no N+1
const user = await db.user.get(id, {
  posts: { comments: true, tags: true },
  profile: true,
});

When to use ORMDB

Application backends where the ORM is generating N+1 queries and you want graph fetches without hand-writing joins
Products that need relational data and semantic (vector) search in one engine instead of syncing two databases
Teams running frequent schema migrations who want automatic safety grading before shipping a change
Real-time features and cache invalidation driven by change streams (CDC) rather than polling

Who it's for: Backend and full-stack engineers who already reach for Prisma, Drizzle, TypeORM, or SQLAlchemy and want the database itself to speak ORM — plus teams adding AI/vector features to an existing relational app.

ORMDB vs. Postgres + a traditional ORM

A traditional stack pairs a relational database with an application-layer ORM that translates object graphs into SQL — the source of N+1 queries and object-relational impedance mismatch. ORMDB moves that graph awareness into the database, so relations, safe migrations, and vector/geo/full-text search are native rather than bolted on with extensions and extra services.
