Schema Builder works best on a wider screen. You can still browse generated SQL on mobile.

SQL Schema Builder

Design tables visually — generates SQL, ORM code, ERD diagrams, and migration diffs.

Custom ENUM Types

No ENUMs — add one to use it as a column type.

CREATE TABLE users (
  id BIGSERIAL PRIMARY KEY,
  email TEXT NOT NULL UNIQUE CHECK (email LIKE '%@%'),
  created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
);
