ARG Architect is a free browser extension that audits any public page in one click. You get one weighted score out of 100 across eight categories: security, performance, architecture, efficiency, payload, accessibility, AI readiness, and DOM. Every failing check explains what fails and how to fix it. Export reports as PDF, Markdown, or JSON. Compare runs or queue ten URLs. No account, no analytics, no tracking. Works on Chrome and Firefox, plus Brave, Edge and Opera through the Chrome Web Store.
