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.

Drawbacks

  • 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.
