# Rebase Documentation

> Rebase is an open-source Postgres admin panel and headless CMS built with React and TypeScript.
> Connect your existing PostgreSQL database and get a full admin UI, REST & GraphQL APIs, a SQL editor,
> row-level security, and an MCP server for AI agents — all generated from your schema.
> Rebase uses Drizzle ORM under the hood and keeps your TypeScript collection definitions as the single source of truth.
> Great for existing projects (it adapts to any Postgres schema) and new ones alike.
