Learn Cua by following end-to-end builds.

Choose the tutorial that matches where you want to work. Each tutorial follows one path from setup to a verifiable result.

• Your first Cloud Fleet - provision an isolated Linux desktop in the cloud and clean it up.
• Drive your first app with Cua Driver - operate a native app on a machine you already have.
• Create a local macOS VM with Lume - install Lume, boot a vanilla Tahoe guest, and connect over SSH.
• Build your first Cua-Bench task - create and verify a simulated computer-use task.

The Fleet tutorial needs Fleet credentials and account access. The Driver tutorial acts on your existing desktop. The Lume tutorial uses its CLI on an Apple Silicon Mac; it is not a local Sandbox SDK tutorial. Each page lists its own prerequisites.

Building a Python or TypeScript application with Driver? Use Cua Driver in process after completing the Driver tutorial.

Once you are comfortable, How-to guides cover specific goals and Reference has the exact APIs.
