From SQL to a visual schema.

Import an existing SQL file and see it become an editable diagram — or design visually and export SQL when you're done.

schema.sql 
CREATE TABLE users (
    id BIGINT PRIMARY KEY,
    name VARCHAR(255),
    email VARCHAR(255)
);
Users
  • id BIGINT PK
  • name VARCHAR(255)
  • email VARCHAR(255)
