About WebGrade
WebGrade turns a public URL into a report you can inspect. It keeps lab measurements, real-user data, and third-party observations in their own lanes so the result stays useful.
What it checks
Four questions, one readable report.
How fast does the page feel in a controlled lab? Can people use it? Can search engines understand it? What do public security and agent-readiness services observe?
How to read it
Scores are signals, not a verdict.
A Lighthouse score describes a lab run. CrUX describes a field collection period and scope. Cloudflare and Observatory report their own observations. Missing data stays unavailable, and an optional provider never runs without your explicit consent.
