Summary

Hi Lighthouse team,

I’m writing to propose adding LightKeeper to the community tools section in your README.md.

LightKeeper is an online service for running Lighthouse audits with different configurations across various global regions.

Key Feature: DevTools-style Waterfall

The unique value of this tool is the Network Waterfall visualization, which is designed to look and feel like the Chrome DevTools Network tab. This helps in debugging infrastructure and regional performance issues that are often hidden in standard reports.

Real-world Example:

I’ve compared Lighthouse runs for your own page: https://developer.chrome.com/docs/lighthouse/overview/ across different regions, specifically comparing us-west-2 vs sa-east-1.

By analyzing the waterfall charts, we can see clear differences in how assets are delivered:

• Protocol Analysis: You can see how static files are served via HTTP/2 vs HTTP/3 depending on the region.
• Regional Bottlenecks: The visualization makes it easy to spot latency issues. For example, I noticed significant CDN performance differences in the Hyderabad region compared to others.

Visuals:

I believe this tool would be a valuable addition for developers who need to audit global performance and debug low-level network bottlenecks.

Would you be open to a PR adding LightKeeper to the README or a relevant documentation section?

Best regards,
Denys Filchakov
