# Blitz.js

Unclassified · [Official website](https://blitzjs.com)

Blitz.js is an open source full-stack toolkit for React applications, built on top of Next.js. It adds features such as authentication, a zero-API data layer that lets front-end code call server functions directly, and code generators. As a framework it runs in the site's own code and does not depend on a third-party tracking service.
