Preact

Preact is a JavaScript library for building component-based user interfaces on a virtual DOM. The homepage describes it as an alternative to React with the same modern API and says it can be used directly in the browser without transpilation. The server-side rendering guide describes a Node.js streaming method for rendering to HTML. New projects are set up with npm init preact, and the license names Jason Miller as the copyright holder.

The getting-started guide says libraries and components written for React work with Preact’s compatibility layer once react and react-dom imports are aliased to Preact.
