Free, browser-based database schema editor — design ERDs and export SQL in seconds.
In the founder's own words — what this project is, and why it matters.
DrawDB is a free, simple, and intuitive database entity relationship (ER) diagram editor and SQL generator. It runs entirely in the browser — no account required. Design your database schema visually, export clean SQL for MySQL, PostgreSQL, SQLite, MariaDB, or Microsoft SQL Server, import existing SQL to reverse-engineer diagrams, and share diagrams via a link. Over 1 million diagrams created. Features include a responsive canvas, keyboard shortcuts, undo/redo, zoom, table relations, constraint management, and a SQL preview pane.
Walk the real path from first touch to done — the big frame is the product itself, and you decide what to look at.

The 'runs entirely in the browser, no account required' positioning is smart. Most DB schema tools have a mandatory sign-up gate that kills casual exploration. DrawDB just works — open the URL, start drawing, export SQL. The one-million-diagrams milestone is a real signal that frictionless tools win.
