This is a project that poimandres has been working on for a while.
A small video showing what it’s capable of: https://twitter.com/0xca0a/status/1394697847556149250

This is similar to CDNs like unpkg et al, but it serves actual assets which are all prepared for the web with reasonable compression. You don’t need to copy a single file. It contains direct access links that you can copy into your app, or starter projects for vanilla threejs as well react threejs.
The tweet above lists the next stages. It will soon support static assets so that you can npm install and import assets into your project. And much more.
