Run multiple Lighthouse tests via Google PageSpeed Insights and get an averaged score. Fast, free, open source, ad-free.
This tool runs Google Lighthouse via the PageSpeed Insights API multiple times and averages the results, giving you a more reliable performance score than a single run.
A single Lighthouse run can vary by 5–15 points depending on server load, network conditions, and timing. Running 3–5 tests and averaging them gives a much more accurate picture of your real-world performance.
