Show HN: Drive any macOS app in the background without stealing the cursor

Every developer who has tried to run GUI automation knows the pain: the robot hijacks your cursor and you can't do anything else while it grinds through tasks. Cua solves this by running macOS app control in a background virtual display, so your actual desktop stays yours. Francesco built this in a weekend after shipping GUI agents for real customers, and that real-world origin shows. The architecture lets AI agents drive any macOS app — clicks, typing, the whole interaction loop — without touching your foreground session. For teams building agentic workflows on desktop software, coding assistants, or QA bots that need to run alongside actual work, this is the missing piece. It's a GitHub project, raw and early, but the problem it solves is REAL and the demand is obvious given how painful cursor-stealing has always been. -> Best for: Builders shipping AI agents or automation on macOS who need background UI control without disrupting the user session.
