LibreDB Studio

LibreDB Studio is a browser-based SQL IDE that is installed next to the database rather than on each user's machine. It runs as a single container, a Helm chart, an OpenShift operator, a native package (Homebrew, Snap, deb, rpm, winget), a desktop build for Linux, or as an npm package embedded in another product.

Ten engines share one interface: PostgreSQL, MySQL, Oracle, SQL Server, SQLite, MongoDB, Redis, Couchbase, ClickHouse and Apache Druid. The editor is Monaco, the same core used by VS Code, with schema-aware autocomplete, multiple tabs that keep independent execution state, visual EXPLAIN plans and a virtualised result grid for large sets.

The schema tools behave the same way on every supported engine: an explorer over tables, views and indexes, ER diagrams generated from real foreign keys with PNG and SVG export, schema snapshots on a timeline, and a diff between any two snapshots or two connections that produces migration SQL.

Natural language to SQL is optional and runs against a model you configure, which can be Gemini, OpenAI, Claude or a local model served through Ollama or LM Studio, so the schema does not have to leave the network.

Team features are part of the same build rather than a paid tier: OIDC single sign-on, role-based access control, a query audit trail, and column-level data masking. The project is MIT licensed.
