Cua

Agent-enablingFreemium

Background desktop control and cross-OS sandboxes for computer-use agents

Overview

About Cua

Cua combines a background driver for native applications with isolated desktops for computer-use agents. The open-source driver connects over MCP or CLI on macOS, Windows, and Linux, while Cua Sandbox and hosted Fleet cover environments across Linux, Windows, macOS, and Android.

So agents can…

Send clicks, typing, and scrolling to a chosen window without taking over the system cursor
Run shell or Python code and GUI actions inside the same isolated computer
Execute training, evaluation, and data-generation workloads in parallel across local sandboxes or hosted fleets

Listing decision

Why Cua is listed

Cua supplies computer-use drivers, sandboxes, fleets, and evaluation infrastructure that agents consume; it enables agent execution rather than acting as the autonomous agent.

Before you choose

Fit and limitations

Best for

Teams building or evaluating computer-use agents that need background native-app control, isolated desktops, or parallel runs across multiple operating systems.

Known limitations

Background input is not universal: some applications require foreground focus. Local sandboxes consume operator CPU, memory, disk, and compatible virtualization; hosted Fleet capacity is separately billed. Cua’s current sandbox documentation also says snapshot and fork operations are not implemented for local sandboxes or Fleet creation paths in cua-sandbox 0.7.0.
