Oh wow, thanks! I never would have thought anyone was keeping an eye on it!

Regarding maturity level - I would yet say it's mature for serious applications with OAuth, local storage etc. Late alpha/early beta stage.

There are some semi-trivial examples on the landing page - most are just UI + input with DB or API fetching in the background, so nothing spectacular.

All of these are crossplatform and render in both web/desktop/mobile and web SDK's or inside the Hypen Gallery apps.

Biggest obstacles to maturity currently are:

- Does not have native platform channels yet

- Renderers need more optimization work

- Ecosystem needs more stability - i.e. test mode and studio still have hiccups

- Error handling and retry story needs improvement

- Some components are still a bit off across desktop/mobile and need syncing

- Resource references derived from state need implementing for better DX

- Protocol isn't binary yet so performance isn't all it could be

But recently things landed that improve maturity quite a lot:

- Accessibility defining & automatic inference has landed, where framework does the best it can to figure it out for you with no intervention

- Animation API has landed with a minimal DX to enable transitions and animations

- Most of tailwind surface is supported and implemented

- Performance improvements being released this week land it in "often 30-50% slower, but sometimes 50% faster than react". Will add benchmarks to docs for visibility.

- CLI improved by a large margin, with expanded template support and easy building

- Cloudflare worker adapter so you can host your app on a worker
