One score. Three audited dimensions.
No black box: weighted across technology choice, version health and engineering quality - methodology published.
How good are the choices?
Each detected technology is ranked inside its category by npm downloads and GitHub stars - the audit measures the quality of choices, not the quantity.
How current are the versions?
Every version is measured against its release history. Falling behind costs points; staying current pays them back.
How well is it built?
Lighthouse results, weighted like an auditor would: accessibility and best practices dominate - performance alone can't hide structural debt.
Can AI agents read your site?
llms.txt, agent access rules, structured data, content without JavaScript - graded A-F on new audits as the checks ship. Displayed alongside the score, not weighted into it yet.
