Everything About Cursor Computer Use

On October 23, 2026, Cursor announced that its coding agents can operate desktop apps on your computer by clicking, typing, and taking screenshots. The lead example shows an agent testing an app it has just built in the iOS Simulator.

The agent does more than write the code now. It confirms the app really works.

Local agents

New: agents in the Cursor desktop app can control desktop apps on your own machine

Cloud agents

Already ran in their own virtual machines with a full desktop, and self-hosted workers can switch computer use on

• Update the Cursor desktop app to the latest version
• Tag Computer Use with @ in your request, or let Cursor pick it when needed
• On macOS, grant the Cursor Computer Use helper app its screen and accessibility permissions
• Watch the first few runs closely

The exact steps may change. Check Cursor’s documentation for the current setup.

• Testing iOS and Android apps in their simulators
• Checking desktop apps after each change
• Clicking through sign-up and checkout flows
• Reproducing bugs described in a report
• Capturing screenshots for pull requests

Build the new settings screen, launch the app in the iOS Simulator, open Settings, switch dark mode on and off, and screenshot both states. Report every crash or layout problem.

• State exactly what to test
• Define what success looks like
• Request screenshots as proof

• Remember a computer-using agent can act as you in any open app
• Close apps holding sensitive data before it runs
• Use a separate macOS user or a test machine for heavy use
• Never let it touch passwords, banking, or payments
• Keep approvals on for any action outside your project

Treat it like handing someone else your mouse: decide first what it may touch.

• Testing through the screen runs slower than automated tests
• Agents can click the wrong thing or misread the screen
• Complex gestures and timing may not work reliably
• It draws more of your AI usage than tasks that only touch code

• Keep unit and end-to-end tests for the core logic
• Save computer use for visual checks and flows that resist automation
• Have the agent convert repeated manual checks into automated tests

Other coding agents, like Claude Code and OpenAI Codex, can also test apps using browser tools and computer-use features. The idea is the same everywhere: agents that verify their own work in a real interface.
