Introduction

What is Rebase?

Section titled “What is Rebase?”

Rebase is an open-source Backend-as-a-Service (BaaS) and admin panel built with React and TypeScript. It gives you everything you need to build production-ready back-office applications on top of PostgreSQL:

  • Schema as Code — Define your data models as TypeScript collections. Rebase generates PostgreSQL tables, a full CRUD UI, REST API endpoints, and type-safe client SDKs from a single source of truth.
  • Instant Admin Panel — A beautiful, fast React-based admin UI with spreadsheet tables, lists, forms, Kanban boards, inline editing, and real-time sync.
  • Integrated Backend — Authentication (JWT + Google OAuth), file storage (local or S3), Row Level Security, entity history, and WebSocket real-time — all built in.
  • Radically Extensible — If you can build it in React, you can add it to Rebase. Custom fields, custom views, plugins, and full access to internal hooks.

Quick Start

Section titled “Quick Start”
pnpm dlx @rebasepro/cli init my-app
cd my-app

init generates a ready-to-run .env for you (secrets, database password, a free local port) — no editing needed to get started. Start the bundled PostgreSQL container, create the tables, then run the dev servers:

docker compose up -d db   # start the database
pnpm run db:push          # create tables from your collections
pnpm dev                  # start backend + frontend

Your admin panel is running at http://localhost:5173 and the API at http://localhost:3001. The first account you register becomes the admin.

→ Follow the full Quickstart guide for a complete walkthrough, including how to connect your own database.
