About QA Toolkit

QA Toolkit is an all-in-one browser extension built for QA engineers and web developers who need fast, reliable tools without switching between apps or DevTools tabs. Tools included: 🎨 Color Picker Pick any color from the page using the native EyeDropper API. Displays HEX, RGB, and HSL values instantly. Keeps a history of your last 10 picks. πŸ” CSS Inspector Click any element on the page to get its optimized CSS selector and full selector path, plus relative and absolute XPath. Ready to copy in one click. πŸ“ Ruler Overlay a pixel ruler on any page. Measure distances between elements, track cursor coordinates, and see nearest-element guide lines β€” all in real time. πŸ“ Lorem Ipsum Generate placeholder text of any length directly in the extension popup β€” no third-party sites required. πŸ–ΌοΈ Lorem img Generate test placeholder images of any size and style directly in the popup β€” no external services or uploads needed. Choose from size presets (favicons, avatars, social cards, banners, edge cases like 1Γ—1 and max dimensions) or set a custom width and height. Pick from 6 background types (solid, gradient, checkerboard, noise, stripes, grid), set labels with dimensions or custom text, and export as PNG, JPEG, WebP, or SVG. Unique feature: embed EXIF orientation tags (1–8) into JPEG to test auto-rotate handling in file upload forms. πŸ”— Redirect Checker Trace the full redirect chain of any URL step by step β€” see every hop, status code, and final destination without leaving the browser. πŸ—„οΈ Storage Inspector View and edit localStorage, sessionStorage, and cookies for the active tab β€” including HttpOnly cookies, which page JavaScript can't touch. Add, edit, and delete values directly, exactly like Chrome DevTools. πŸ•΅οΈ User Agent Switcher Spoof your browser's User Agent per tab using session rules. Test how your site responds to different devices and browsers without restarting. πŸ“¦ Mock Server Intercept any network request and return a custom JSON response. Define your own status code, headers, and body β€” no backend needed. { } JSON Formatter Paste or capture raw JSON and get it formatted with syntax highlighting. Supports multiple themes (Monokai, Nord, One Dark, Spectrum, GitHub). πŸ–ΌοΈ OG Inspector Inspect Open Graph and Twitter Card meta tags on any page. Preview exactly how your link will look when shared on Twitter/X, Facebook, LinkedIn, Telegram, and Discord. πŸ“‹ iFrame Inspector List all iFrames on the current page with their source URLs, dimensions, and sandbox attributes. Spot hidden iFrames instantly. 🎨 Page Painter Draw, highlight, and annotate directly on any webpage. Useful for visual bug reports and quick UI mockups during reviews. β™Ώ Accessibility Checker Run a real WCAG audit powered by axe-core, the industry-standard accessibility engine β€” entirely local, right from your browser. Get detailed violation reports, an accessibility tree, real keyboard-focus testing, color contrast analysis, audit history and comparisons, and exportable reports (JSON/CSV/HTML) β€” all in a dedicated side panel. πŸ”“ Decoder Decode and encode URL parameters, HTML entities, Base64, Unicode escapes, and JSON β€” plus decode JWT tokens (header, payload, and expiry, without touching the signature). Auto-detects the format, or pick one manually. Grab a value straight from any element on the page with one click. Runs entirely locally β€” nothing is ever sent anywhere.
