Ask Claude About Your PageSpeed and Core Web Vitals Data
Lang Quang PSI connects Claude to Google's PageSpeed Insights and Chrome UX Report APIs using your own API key. Run Lighthouse audits and pull real-user speed data for any URL in a normal conversation.
What you can ask it
The connector calls the same Lighthouse and CrUX History endpoints available in the PageSpeed Insights API, using your own API key.
Lighthouse audit scores
Performance, accessibility, best practices, and SEO scores for mobile or desktop, for any URL you give it.
Core Web Vitals for a page
LCP, CLS, total blocking time, and speed index for a specific page.
Real-user field data
CrUX field data over the last 40 weeks, by page or by whole site, from real visitors rather than a lab test.
Field data by device
Filter Core Web Vitals history by phone, desktop, or tablet to see where performance actually differs.
Ask It Like You'd Ask a Colleague
Once connected, here's the kind of thing you can type straight into Claude.
“Run a mobile PageSpeed audit on our homepage.”
“What's the Lighthouse SEO score for /pricing?”
“Show me the last 40 weeks of Core Web Vitals for our site.”
“Is our LCP getting better or worse on phones?”
How Lang Quang PSI gets set up
Unlike our Google Sign-in connectors, PSI runs on a PageSpeed Insights API key you provide.
Built on Google's own API, nothing more
No Google Sign-in required
PSI has no OAuth scope because it doesn't touch your Google account. You supply your own PageSpeed Insights API key instead.
Your key, your quota
Requests run against the API key you provide, not a shared LangQuang key, so your usage never competes with another client's.
Data isn't stored beyond your session
Each answer is fetched live from the PageSpeed Insights and CrUX History APIs for that conversation. We don't cache results.
Disconnect anytime
Remove your API key from the LangQuang dashboard at any time to disconnect the connector.
