Cua Spaces gives computer-use agents a desktop on hardware a team already controls, then lets people watch that screen and take over. This early-access launch adds Hetzner and AWS as places those desktops can run, alongside Macs and Linux boxes the team already has. It comes four days after Cua ended its hosted product, Cua Cloud and Fleets, on 18 October 2026. The path Cua documents now is a desktop on a machine the team owns, or a VM in the team's own cloud account. You link an account once with cua cloud connect hetzner or aws, and new Spaces start on servers in that account. The cloud provider bills for the VMs. Cua supplies the app, sharing, and the relay that reaches them. Self-hosting on Macs and Linux is available now. Running existing E2B and Daytona programs unchanged is still early access, and Cua is sending that compatibility build first to people who ask for it. Cua priced 256 reinforcement-learning sandboxes, eight hours a day for a month, at $10,200 on E2B and $700 on Cua Spaces. In the company's tests, the next batch on a server that was already running took 10.6 seconds to create and 139 milliseconds to the first command. Francesco Bonacci founded the San Francisco company in March 2025 after working on Windows Agent Arena at Microsoft with Dillon DuPont, who joined soon after. Cua is in Y Combinator's X25 batch.
