About

Demo of a UI testing agent built on OpenAI's Computer Use model and the Responses API. Drives a browser to test apps end-to-end.

What it does

A runnable monorepo for exploring model-guided frontend checks. A configuration screen accepts a target URL and test case, while a Node service coordinates the model and Playwright. A bundled storefront supplies a safe example, and the interface shows task progress alongside the agent interaction.

Why it's ranked here

Worth a short technical trial because it exposes the complete interaction loop, not merely an isolated API snippet. The included interface, service, and sample storefront make the concept tangible. Its preview status, explicit security warnings, and configuration inconsistency keep it firmly in demonstration territory.

What's good

The project separates the reusable agent service from the configuration interface and disposable example application. Users can change both the target URL and test case through the interface. Playwright supplies a real browser, while the visible progress and side panel help people understand what the agent is doing.

Tradeoffs

Computer use remains a preview feature and may make mistakes or encounter exploits. The authors restrict intended use to test environments, warn against authenticated or high-stakes work, and prohibit real production data. Setup requires an OpenAI API key, three environment files, Node dependencies, and Playwright browser installation. The documented service port also conflicts with the server default.

How to use it well

Use it to prototype model-guided checks against disposable web environments and to study how a browser agent handles written test steps. Start with the bundled storefront, then point the configuration interface at a controlled application. Extract the service logic when integrating elsewhere. Do not treat it as coverage for authenticated production workflows, sensitive data, or high-stakes validation.

Technical notes+

The root package.json defines a private npm workspace containing frontend, cua-server, and sample-test-app, with concurrently launching all three development processes. frontend/app/page.tsx provides responsive configuration, task-step, and agent-panel regions, while frontend/lib/utils.ts parses a JSON test case and requires a steps array. cua-server/src/index.ts exposes Socket.IO events for messages, test initiation, and status updates, with configurable CORS. README.md documents ws://localhost:8080, but cua-server/src/index.ts defaults SOCKET_PORT to 8000, so local configuration may be required.
