Supabase CLI is a command‑line tool that lets developers manage every part of a Supabase backend locally and in production—running the platform on a local machine, handling PostgreSQL migrations and backups, creating and deploying edge Functions, and generating TypeScript types from the database schema. It is aimed at developers building applications with Supabase (an open‑source alternative to Firebase) who want a streamlined, scriptable workflow for setup, development, and deployment.
