Claude Code for Chrome Browser Testing
The Claude Code Chrome integration lets the agent launch your browser and click around like a real user, but it's slow and can be unreliable — especially with screenshots. It's worth knowing about for quick checks, but the next lesson covers a faster, more practical tool for browser testing in your dev workflow.
This lesson covers the built-in Chrome integration for Claude Code, which lets the agent open your actual browser, navigate pages, click buttons, and interact with your app just like a user would. You'll see how to enable it with the /chrome command and watch a live demo where Claude launches Chrome, creates a to-do list, adds an item, and checks it off — all on its own.
The demo also shows the current limitations honestly. The integration is slow, with noticeable delays between each action, and the screenshot functionality doesn't always work reliably. It's still useful for quick one-off checks or verifying that a user flow doesn't hit errors, but it's not ideal for tight build-test-iterate cycles. The next lesson introduces a faster, more reliable alternative purpose-built for agent workflows.
