Ask Claude About Your PageSpeed and Core Web Vitals Data
Lang Quang PSI connects Claude to Google's PageSpeed Insights API 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 endpoint 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
p75 LCP, INP, and CLS from real Chrome users, for any page with enough traffic to report. Point-in-time, not a trend.
Mobile or desktop
Run the same audit against either strategy 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 Core Web Vitals for our homepage.”
“How does our LCP compare on phones versus desktop?”
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.
Stored only when you save a report
Answers in Claude are fetched live for that conversation and not kept. If you save a report in the LangQuang dashboard, its figures are stored so you can open or share it later, until you delete it.
Disconnect anytime
Remove your API key from the LangQuang dashboard at any time to disconnect the connector.
