Supabase Schema Designer

This free visual schema designer makes it easy to plan your Supabase database before writing any SQL. Add tables, define columns with precise PostgreSQL types, set constraints like primary keys, unique indexes, and foreign key references, then generate production-ready SQL with a single click.

The generated SQL follows Supabase conventions including uuid DEFAULT gen_random_uuid() for primary keys and timestamptz DEFAULT now() for timestamps. Enable RLS policy generation to get starter Row Level Security policies for every table.

Supports all common PostgreSQL types including text, integer, bigint, boolean, timestamptz, uuid, jsonb, numeric, serial, and more. Perfect for prototyping your database schema before running migrations in the Supabase Dashboard or CLI.
