AdminJS

AdminJS is a free, open‑source library that auto‑generates a fully customizable admin interface for any Node.js app. It integrates with popular ORMs/ODMs and databases, offering built‑in CRUD, filtering, role‑based access control, custom actions, and a React‑based design system. Install via npm and plug into Express, Nest, Hapi, or Firebase, then tailor the UI with CSS or custom components. It speeds up admin panel development, saving weeks of work while remaining highly flexible.
