SQL Designer - Free and Open Source ERD tool for all major relational DBs

SQL Designer is a free, browser-based tool for visually designing database schemas. Drag out tables, define columns and relationships, and get a clean entity-relationship diagram — no install, no account needed to start. Built for developers who want to plan their data model before writing migrations.
