Curator's take

The broadest open stack for computer-use agents: one sandbox API that runs a desktop locally or on their cloud, Cua Driver that operates native apps on macOS, Windows and Linux in the background without taking your pointer (CLI, MCP or typed SDKs), Lume for macOS and Linux VMs on Apple Silicon, Cua Bench for tasks and trajectories, and CUA-S1, small decision models for forms. Use it when your agent has to touch software that has no API. The breadth is the cost: many components, a cloud product (Fleets) promoted throughout, and the installer signs you in. If your agent only needs the web, browser-use is far less; if it only needs to run code, a plain sandbox is enough.
