Sketch your database before you build it.
Drag out tables, wire up foreign keys, and export clean, ready-to-run SQL.
Visual table builder
Add tables and columns with real MySQL types, keys, and constraints — see your schema take shape as you build it.
Drag-to-connect relationships
Draw foreign keys straight from one column to another. Crow's-foot notation updates live as you move tables around.
One-click SQL export
Get a clean CREATE TABLE script, correctly ordered, ready to paste into phpMyAdmin, MySQL Workbench, or your migration files.
Import an existing schema
Paste in SQL you already have and ERD Studio reconstructs the diagram — great for documenting a database you inherited.
Share a read-only link
Generate a link teammates can open to view the diagram — no account needed on their end.
