Free, browser-based entity-relationship diagram editor with one-click SQL generation — design a schema visually and export working SQL.
Why we recommend it
Product and UX designers increasingly need to reason about data models, not just screens. drawDB turns an ERD into a real, exportable schema without opening a database client.
Strengths
- Free and open source under AGPL-3.0. Visual ERD editor, generates SQL for multiple database engines, import existing schemas, no account needed.
Keep in mind
- Built for schema design, not data modeling theory — it won't catch normalization mistakes for you. AGPL-3.0 licensing means self-hosted derivatives have copyleft obligations, worth reading before building on top of it.
