HTML rendered via what? nw.js? Electron? I feel like the former is a bit more solid by virtue of having been around longer, but unfortunately both ecosystems are such a mess a11y-wise that I haven't really delved into them. In any case, it's probably a safer bet than something like GTK/QT which is either entirely or mostly inaccessible. But HTML rendered in a browser at least has the potential to be highly accessible, and one workaround for poor a11y implementation of nw.js/Electron would be exposing the HTML to another browser over a local port with functions callable via JS over the server port.
Eve is served as remotely as a webapp, and it'll run in all modern browsers. Presently it's supporting Chrome first; but support for FF, IE Edge and others is on the map. Along the way, we're looking forward to gathering feedback on how we can improve user experience across the board, so please drop us a few issues on how we can make things better if you get the chance to try it out.
