Lighthouse
Find specific page problems before asking AI to fix them
BrowserFree Chrome desktop audit · lab results, not real-user measurements
Open Lighthouse Why this one
Replace 'make my site faster' with a report naming concrete opportunities and failed checks. Useful for choosing one change and measuring it again under comparable conditions.
Try this first
Open a page you manage in desktop Chrome. In DevTools, run a Lighthouse mobile audit and read one performance or accessibility finding before changing the code.
How it helps your AI
Give the assistant a specific audit finding and relevant code. Ask for a small fix, then rerun the audit and check the page still works.
