Frequently Asked Questions
Should I Block Chrome-Lighthouse?
Only if no one on your team relies on it. Chrome-Lighthouse may support uptime monitoring, performance tests, or audits. Blocking it without checking first can silently disrupt those workflows. For context, 1% of the top websites we track currently have robots.txt rules for Chrome-Lighthouse.
Does Chrome-Lighthouse Follow Robots.txt Rules?
No. Chrome-Lighthouse is not expected to follow robots.txt directives, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Does Chrome-Lighthouse Access Private Content?
Only when configured with access. A team may grant Chrome-Lighthouse credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
Why Is Chrome-Lighthouse Visiting My Website?
Someone, most likely on your own team, configured Chrome-Lighthouse to check your site. Uptime monitors, performance testers, and audit tools visit only the sites or endpoints they are told to watch.
How Can I Tell if Chrome-Lighthouse Is Visiting My Website?
Agent Analytics tracks Chrome-Lighthouse visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "Chrome-Lighthouse". Look for repeated checks of the same pages or endpoints at regular intervals. Because Chrome-Lighthouse does not publish a verification method, any client can claim its identity and a log match is only a clue.
