Webarchy, a Desktop Inside a Tab

Field notes

The desktop uses binary-split tiling: adding a widget divides an existing tile, while closing one lets the remaining tiles expand. Its app model is unusually explicit—a module must provide mount(el, ctx) and destroy(), allowing pasted JavaScript or URL-loaded modules to become tiles. The page lists nine virtual desktops, persistent layout and widget data, and built-in examples such as Intum Tasks, Weather, Pomodoro, and a browser.
