What is Chrome-Lighthouse?

About

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. You can see how often Chrome-Lighthouse visits your website by setting up Dark Visitors agent analytics.

How Do I Block Chrome-Lighthouse?

⚠️ Manual Robots.txt Edits Are Not Scalable
New agents are created every day. Instead, serve a continuously updating robots.txt that blocks new agents automatically.
Set Up Automatic Robots.txt

You can block Chrome-Lighthouse or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
