windows-web
A browser-based Windows 11 simulation built for human annotation and computer-use agent research.
windows-web is interesting because it sits on the boundary between product UI and research infrastructure.
On the surface it is a browser-based Windows 11 simulation. Underneath, it is clearly built as an interaction environment: it has a window manager, task switching, a start menu, context menus, a virtual filesystem, and a suite of lightweight apps including File Explorer, Terminal, Notepad, Paint, Mail, Maps, Store, and more.
What makes it useful is not pixel-perfect mimicry. It is that the environment exposes the kinds of structured actions computer-use systems need: opening applications, navigating folders, manipulating files, resizing windows, handling menus, and moving through a desktop workflow in a controllable way.
The in-memory filesystem is a good example of the project’s intent. It models drives, folders, files, path normalization, creation, deletion, copy, move, and rename operations, which is exactly the kind of substrate you want if you are collecting annotations or evaluating an autonomous agent against desktop-like tasks without handing it a real machine.
The result is a pragmatic middle layer: more realistic than a toy benchmark, safer and more inspectable than a real desktop, and much easier to instrument for human annotation and agent evaluation.
