Supabase Schema Designer
Visually design your Supabase database tables, columns, and constraints, then generate draft SQL to review and test.
Using this tool
Add tables and columns, choose constraints, and inspect the draft SQL. Enabling RLS adds the database setting without inventing an access policy for your users.
What the output does not tell you
Review identifiers, defaults, foreign keys, migration order, and types before running the SQL. An RLS-enabled table needs explicit policies for normal client access; define these around your real ownership and role rules, then test allowed and denied requests. This tool does not validate a production schema.
