LibreDB

Hi, we're LibreDB

Database tools we'd want to use ourselves. Most of them open source, all of them built on one foundation.

We make three things.

Two are open source and free: a web-based SQL/NoSQL IDE that runs in your browser, and a small embeddable database engine you can read end to end. The third is LibreDB Platform, a commercial product for teams and enterprises, and it's what pays for the open-source work. So Studio and the engine stay free, and stay maintained.

Studio is MIT because it has to be. You cannot place a per-seat licensed, feature-gated tool into every environment you own — so nothing is held back for a paid edition. Platform charges for a service, not for the features.

One foundation, three products. Here's the tour.

LibreDB Studio: the open-source SQL/NoSQL web IDE

Databases moved to the cloud. The tools that read them stayed on the laptop. Studio is the editor that goes the other way: it deploys next to the data — a container, a Helm chart, an operator, a one-click template, or an npm package inside your own product. Nothing has to face outward, and it works on a 4K monitor or a phone.

Ten engines, one interface: PostgreSQL, MySQL, Oracle, SQL Server, SQLite, MongoDB, Redis, Couchbase, ClickHouse, Apache Druid
A real IDE: Monaco engine, schema-aware autocomplete, multi-tab workspace, visual EXPLAIN
See your schema: interactive ER diagrams, schema diff, migration SQL, snapshot timeline
AI with your own model: NL2SQL against Gemini, OpenAI, or a local LLM
Nothing behind a wall: RBAC, SSO (OIDC), query audit trail and ER diagrams all ship under MIT

LibreDB: the engine underneath

Multi-model without the magic. One core, three lenses, every line tested.

A small, readable, embeddable database written in TypeScript. Key-value, document, and relational APIs are thin lenses over a single ordered key-value core, not three engines bolted together. Zero runtime dependencies, in-memory or file-backed, with crash recovery proven by deterministic simulation testing.

The kernel is under 600 lines. You can open the source and actually learn how a database works.

It's pre-alpha and aimed at test and dev environments today: small enough to understand, serious enough to grow.

LibreDB Platform: for teams, and how we keep the lights on

Distributing database credentials by hand doesn't scale, and it isn't safe. Platform replaces that with a managed, multi-tenant workspace: admins decide who can reach which database, every query is logged, and teams collaborate without anyone copy-pasting a connection string.

Built on the same Studio engine, with governance on top: RBAC, encrypted credentials, full query audit, billing and plans. This is the commercial product that funds everything above it.

How it all fits together

LibreDB            →   LibreDB Studio      →   LibreDB Platform
the embeddable         the open-source         the governed,
database engine        IDE built on it         multi-tenant product
(open source)          (open source)           (commercial)

Start anywhere. Embed the engine in your app, run Studio for your own databases, or bring Platform in when your team needs control and an audit trail.
