§ Positioning
The runtime layer for computer-use agents - not an environment company itself, but the substrate CUA environments execute on.
Best for · Teams building or running computer-use environments who need fast, resettable desktop sandboxes.
Team · Founded by Francesco Bonacci and Dillon DuPont (YC X25); 9k+ GitHub stars in 4 months.
Focus · Open-source sandboxes, SDKs, and cloud VMs for running computer-use agents at scale - near-native macOS/Linux/Windows desktop execution with snapshot/restore and RL dataloader.
Notable customers · Open-source community; thousands of developers
§ Infrastructure
Unscored - adjacent infrastructure
Cua provides execution infrastructure that RL environments run on, rather than building environments itself. Listed here for context but not scored against the environment-native rubric.
