Popularity is tracked separately. Support, ads, sponsorships, and tips never affect these signals.

Why it matters

Useful for developers who want agents to click through a real local app and inspect browser state instead of guessing from server logs or HTML fragments.

Who should use it

frontend developersfull-stack developersClaude Code usersteams testing local web apps

Who should skip it

Skip if the source link, docs, or setup requirements do not match your workflow.

Risk explanation

The server can click, type, run JavaScript, and capture browser state in any host you allow, so keep the allowlist narrow and avoid widening it to accounts or internal apps unless you trust the session boundary.
