Does anyone have a link to the web assembly component model, and is there any alternative? Maybe there can be some kind of universal device driver plugin or so

Does anyone have a link to the web assembly component model, and is there any alternative? Maybe there can be some kind of universal device driver plugin or something. It's weird to me that there wasn't initially an organized effort to escape the web browser by coming up with some sort of UI system or ways to integrate other devices etc. Don't know if that has changed.
