FAQ

Do I need a Google API key? No, a built-in key is used. For very large or frequent jobs you can enter your own key to use your own Google quota. Why is there no field data for some pages? Google only has real-user (CrUX) data for pages/origins with enough Chrome traffic. fieldDataSource shows whether it's page-level or origin-level. How long does it take? Google needs about 10–30 s per audit. With concurrency 4, 100 audits take about 10 minutes. Raise maxConcurrency to go faster. Why do scores differ from my browser? Lighthouse lab results vary run to run and by location. Use field data for real-user truth. Can I get the full Lighthouse JSON? The table keeps the most useful fields.
