What is Chrome-Lighthouse?
Chrome-Lighthouse is an automated, open-source tool that audits web pages for performance, accessibility, progressive web apps, SEO, and best practices. It runs a series of audits against a page and generates a comprehensive report on how well the page did. Agent Analytics can track when it visits your website.

Frequently Asked Questions
Should I Block Chrome-Lighthouse?
Only if nobody you work with uses it. Chrome-Lighthouse is the kind of tool a team points at its own site for uptime checks, performance tests, and audits. If someone on your team relies on it, blocking it silently breaks their monitoring. For comparison, 1% of the top websites we track already have robots.txt rules for Chrome-Lighthouse.
Does Chrome-Lighthouse Follow Robots.txt Rules?
No. Chrome-Lighthouse is not expected to follow robots.txt rules, so a disallow rule only states your preference. Enforce the block with firewall or server rules, then confirm in Agent Analytics that its requests actually stop.
Does Chrome-Lighthouse Access Private Content?
Only if its owner sets that up. Monitoring tools check whatever they are configured to check, which can include staging sites and private health endpoints when a team grants access. Uninvited, Chrome-Lighthouse sees only public pages.
Why Is Chrome-Lighthouse Visiting My Website?
Someone pointed Chrome-Lighthouse at your site, most likely your own team. Uptime monitors, performance testers, and audit tools only visit the sites they are configured 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 regular checks of the same pages or endpoints, often minutes apart. Keep in mind that Chrome-Lighthouse doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
