# ARG Architect

Architecture-first software engineering for scalable systems

## What it is

Maker-submitted description:

Arg Architect audits the website you choose and tells you what is wrong, why it matters, and how to fix it. Everything runs inside your browser: reports stay on your device and are never uploaded. WHAT IT CHECKS - Security: security headers (CSP, HSTS, frame protection, referrer, and permissions policies), cookies, mixed content, exposed secrets, known-vulnerable client libraries, and disclosed server versions that are out of upstream support, grouped by the attack each defense stops. - Performance: Core Web Vitals and load timings measured over repeated controlled page loads, with the median of every run, and a slow LCP explained by its cause. - Architecture: third-party dependencies, API origins, redirect chains, script errors and failed requests during the load, and the detected technology stack. - Payload and efficiency: JavaScript, CSS, image and font weight, image formats and sizing, caching, compression, duplicate requests, and HTTP versions. - Accessibility and DOM: image alt text, form labels, heading structure, landmarks, duplicate ids, page size, and on a phone-sized window: layout fit, touch target size, and legible text size. - AI readiness: robots.txt rules judged by crawler role (letting AI search and citation crawlers in, keeping training and scraper crawlers out), sitemaps, llms.txt, structured data, and agent discovery, with llms.txt relevance judged by a built-in multilingual language model. FINDINGS YOU CAN ACT ON - Every failing check explains the problem, names exactly what fails (the header, the file, the element, the library and its advisories), and recommends a fix. Copy any finding as a ticket draft for your issue tracker. HOW IT WORKS - Audit the current tab, or queue up to 10 URLs at once. - Audits run in their own window, so your browsing is never touched, and you get a notification when the queue finishes. - Cookie banners are answered with reject or essential-only, never accept. - Choose Quick, Standard or Thorough measurement in Settings. HISTORY AND COMPARISON - Saved reports are grouped by day. Compare any two runs side by side, every score, check and measurement, to track progress over time or between two versions of a site. Reports made with another version of Arg Architect are flagged before you compare them, because checks and scoring can differ. Export reports and comparisons as PDF, Markdown, or JSON. PRIVATE BY DESIGN - No account, no analytics, no tracking. - The language model and the vulnerability database ship inside the extension. - Nothing runs on the pages you browse normally; the page collectors run only on the site being audited, only during the audit. - Optional lookups that send a hostname to a DNS service (CDN detection, AI discovery) are off by default.
