What you get
Real measurements
Lab data from Lighthouse, plus real-user data from Chrome's field dataset where it's available.
Ranked fixes
An AI model orders the failing audits by estimated time saved. Every fix is tied to a real failing audit.
Shareable reports
Each audit gets its own link you can send to a teammate.
How it works
Audits are limited to 5 per hour, and AI fixes can pause for the rest of the day when the free daily quota is used.
