LibreDB Studio is an open-source database IDE that runs on infrastructure you control and provides a browser-based workspace, with platform-specific local installation options. It supports connections to a range of relational, document, key-value, and analytics databases. Database professionals can browse schemas and objects, write and run queries, inspect execution plans, compare schemas, and view relationships in ER diagrams. The workspace also includes query history and audit records, session and query monitoring, role-based access controls, and OpenID Connect single sign-on. Designed for developers, data engineers, and database administrators, Studio can be deployed near the databases it accesses, keeping connections within a private network. The self-hosted software is available under the MIT license.
