OpenClick is the open-source macOS click agent nobody asked Apple for

Riccardo Arvizzigno shipped OpenClick on Product Hunt today. It's an open-source CLI agent that controls macOS through the Accessibility APIs. Tell it open Calculator and compute 17 times 23, and it plans, screenshots, reads the AX tree, executes, verifies. Model-agnostic, runs Anthropic, OpenAI, or your local model, no backend server, MIT licensed.

The interesting layer is what the agent reads. Not raw video like Standard Intelligence, not OS-level virtual environment like Manus Cloud Computer, but the macOS accessibility tree plus screenshots. AX trees give you semantic structure for free. Screenshots fill the gap when the app draws its own UI. The trade-off is everything Apple has not exposed via Accessibility APIs is invisible to the agent, which is why OpenClick is rough on canvas-heavy apps and pretty solid on Mail, Finder, Calculator, browser nav.

This is v0.2.0 by one developer, not a polished product. But it's the cleanest open-source macOS agent on the layer between what the OS gives you and what an LLM can plan over. The agent-VM bet split is now four-way: raw video, virtualized desktop, raw VM with root, and accessibility-tree. OpenClick is the first credible community attempt at the fourth.
