Heya 
, I just published https://peace.mk, a website for 
Peace, my automation framework project.
Although it's been worked on for about 2 years (across different repos), the project is not yet at the "useful" stage. That said, I think people would find the way things are done, and the concepts it implements to be something in the "I wish this exists" bucket.
There is a WASM live demo for a simple "file download" item spec, which uses the same code as the native download example (it's the same example!).
I was hoping to have the app_cycle example demoable before publishing the website, but realized "this is much bigger than I thought" many times while coding it 
enjoy
