# Preact

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

Preact is an open source JavaScript library for building user interfaces, offering an API close to React in a very small package. It renders components with a virtual DOM and can use a compatibility layer to run many React libraries. It runs entirely in the site's own code and does not set cookies or send data to a third party by itself.
