One audit grades what runs a site, how current it is, how well it's built - and how ready it is for the AI web.
Free plan - 5 audits a month. No card required.
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.

Watch your stack. And theirs.
Fresh audits of the sites you care about - yours before an outdated library becomes an incident, competitors before they pull ahead.

Built for people who answer for websites.
Agencies
Sell the audit, keep the retainer - branded reports and monthly client digests for every site you manage.
Developers & freelancers
Watch your own sites and your competitors'. Catch version drift and quality regressions before they page you.
Site owners
One number tells you where you stand - and the audit tells your developers exactly what to fix.
Security
Live-site vulnerabilities, end-of-life and version freshness - reconnaissance without an agent.
Watch your stack. From free.
One-off audits are the free taste - the subscription is the watching: alerts, history, branded reports.
