### What we like

Extends HTML to allow building web apps. No need to wait for client-side JS - content streamed in, but optional support for async sections. State declared in markup with updates auto-propagated. Zero config setup using Vite. Supports various styling options, including CSS modules and imported styles.

### Tradeoffs

Lots of custom tags which means it’s not really HTML.
