Dev Browser FAQs

Question 1

Does Dev Browser support headless execution?

Accepted Answer

Yes, it supports a --headless flag for background execution. This is particularly useful for automated scraping or testing tasks where you don't need a visible browser window, allowing for a cleaner and more efficient workflow.

Question 2

What is the Dev Browser Claude Code Skill?

Accepted Answer

Dev Browser is a specialized capability that allows Claude to control a persistent Chromium browser. It enables Claude to navigate websites, fill forms, take screenshots, and extract data across multiple execution steps while maintaining session state like login cookies and localStorage.

Question 3

How does persistent state benefit browser automation?

Accepted Answer

Persistent state preserves cookies and DOM state between script runs. This means you can log into a site in one step and perform actions in subsequent steps without losing your session, allowing for complex, multi-stage workflows that traditional one-off scripts can't handle.

Question 4

What makes ARIA snapshots better than traditional selectors?

Accepted Answer

ARIA snapshots use semantic accessibility trees to identify elements by their role (like 'button' or 'link') and accessible name. This is more reliable for AI interaction because it focuses on user-perceived elements rather than fragile CSS classes or IDs that change frequently.

Question 5

Can I use this skill for automated application testing?

Accepted Answer

Yes. It is ideal for web application testing. You can write incremental scripts to verify UI behavior, capture visual feedback via screenshots, and automate repetitive user flows within a real browser environment to ensure your application works as intended.
