You're right. The blog post announcing the NaCl port is dated 9/2015. I don't believe that effort is still active nor am I aware of any official efforts to get Qt / QML run on WebAssembly. There is the Qt Quick WebGL Streaming official project - https://news.ycombinator.com/item?id=13744631 https://news.ycombinator.com/item?id=13744631 - but this is a different thing entirely: instead of running the QML app on the client, the app runs natively on the server. Instead of rendering the UI directly using OpenGL, the scenegraph generates a stream of WebGL commands. An accompanying JavaScript library receives this command stream through a web socket an replays it in the browser on a WebGL canvas. Kind of like what Remote Desktop does.
