About DEVnightmareFIX — Edge Stress Tester
Ship with fewer surprises. DEVnightmareFIX turns the page you’re on into a QA lab: controlled stress, fast DOM sweeps, and exportable reports — without leaving Chrome.
WHAT IT DOES
• Flaky network — simulated fetch/XHR failures, delays, and offline-style behavior on the current tab.
• Date & time chaos — skew clocks and edge-case modes so time-dependent UI can’t hide.
• Angry-user flows — burst clicks and hostile form fills to catch brittle handlers.
• Chaos matrix — viewport, storage, visibility, media queries, APIs, and more (toggle what you need).
• Accessibility sweep — headings, controls, images, tables, focus, and common WCAG-ish smells.
• Security heuristics — mixed content, CSP meta signals, SRI gaps, iframes, risky URLs, storage key names, and many DOM-level checks (heuristics, not a full pentest).
• SEO snapshot — titles, meta, canonical, Open Graph, Twitter cards, JSON-LD health, hreflang hints, and more.
• Same-origin security crawl — optionally auto-navigate the same tab across internal links and merge findings (user-started; bounded page count).
• Reports — save and open structured findings; export-friendly workflow. First saved report is free; unlimited after one-time purchase.
WHO IT’S FOR
Frontend engineers, QA, and indie teams who want one tool for “break my assumptions” plus quick a11y/security/SEO signals on real pages.
WHAT IT’S NOT
Not a replacement for Lighthouse scores, enterprise DAST, or server-side header audits. It complements lab tools with messy-world simulation and fast DOM review.
Keyboard shortcuts and a context menu are included for power users. One free saved report included; one-time purchase for unlimited runs and reports.
