drawDB is a free, open-source browser-based tool for designing database schemas through visual entity-relationship diagrams. Users can generate SQL DDL scripts for multiple database dialects including PostgreSQL, MySQL, SQLite, MariaDB, SQL Server, and Oracle, and reverse-engineer existing schemas by importing SQL or DBML files.

The free editor requires no account and stores diagrams locally in the browser. drawDB Pro adds cloud storage, real-time team collaboration, diagram sharing, version history, AI-assisted schema design, and GitHub integration. The tool also ships an official Model Context Protocol (MCP) server allowing AI assistants to read diagram schemas.

DrawDB is fully open source under the AGPL-3.0 license and can be self-hosted using Docker. Features include customizable editor layouts, keyboard shortcuts, presentation mode, issue detection, migration generation, and export to multiple formats including JSON, images, Mermaid, and Markdown.
