DEVnightmareFIX — Edge Stress Tester

Stress test: network, time, a11y, security, SEO, chaos, crawl, reports. One free report, then pay for unlimited.

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.
