Cua
Containerised desktop sandboxes for agents, with a focus on running macOS and Linux environments safely.
Solves the part everyone else leaves to you: safe environments. It provides containerised macOS and Linux desktops for agents to work in, so the sandbox is infrastructure rather than an exercise for the reader.
Best for
Anyone who needs the sandbox solved before the agent is.
Watch out
Infrastructure, not an agent. You still bring the model and the loop. The licence is not uniformly MIT: Cua Spaces is source-available under FSL-1.1-MIT. Several packages are marked deprecated and unmaintained, and the project tells you outright not to run cuabot, which has known security issues.
