Yes. The drawDB editor is free and open-source (AGPL-3.0) and needs no account. drawDB Pro adds paid plans for teams with real-time collaboration, cloud storage, AI-assisted schema design, and GitHub sync.

Do I need an account to use drawDB?

No. The free editor runs entirely in your browser and saves diagrams locally, with no sign-up required. An account is only needed for Pro features such as cloud storage and real-time collaboration.

Which databases does drawDB support?

drawDB supports Generic, MySQL, PostgreSQL, SQLite, MariaDB, Microsoft SQL Server, and Oracle (beta) — for both generating SQL and importing existing SQL.

Can drawDB generate SQL from a diagram?

Yes. drawDB generates ready-to-run SQL DDL scripts for each supported dialect directly from your entity-relationship diagram.

Can drawDB import an existing database schema?

Yes. Paste an existing SQL DDL script and drawDB reverse-engineers it into a visual diagram automatically. drawDB also supports DBML import and export.

Can AI agents use drawDB?

Yes. drawDB ships an official Model Context Protocol (MCP) server (@drawdb/mcp) that lets AI assistants such as Claude, Cursor, and Windsurf read a diagram's schema directly, read-only.
