It is hard to automate with computer-use agents because of weird pop-ups, lack of a DOM like browsers, random clicks, and cost at scale.

We built an agent harness and sandbox to automate any legacy software. Our Windows Sandbox (SmolVM) is open-source and can be used with a Python SDK or CLI - https://github.com/CelestoAI/SmolVM

We will also publish our agent harness benchmark report soon.
