QAKit

QAKit - All-in-one browser toolkit for QA engineers and web developers QAKit puts the tools you reach for every day inside a single, fast popup. No more juggling DevTools tabs, command-line scripts, or half a dozen single-purpose extensions — QAKit has them in one place, designed for the way QAs and developers actually work. Inspect & Measure Element Inspector shows test IDs, computed CSS, accessibility role, and the box model on hover Spacing Inspector visualises margin and padding with coloured guides Pixel Ruler for precise on-screen measurements Responsive Preview at common device widths Capture Region, Element, and Full Page screenshots — copied to clipboard with a one-click "Save as PNG" toast Annotate any page before capturing (arrows, shapes, text, highlights) Data & Network Live Analytics feed — captures GTM, GA4, Adobe, Tealium, Meta Pixel, Segment, Floodlight, and DDL events as they fire Network Mock — intercept HTTP requests and return custom JSON, status codes, redirects, or block them entirely Headers Modifier — inject auth tokens, override CORS, or customise any request/response header Page Audit Comprehensive scan with grades for Performance, Security, and Accessibility. Detects broken links, broken images, spelling errors, console errors, missing security headers, contrast failures, and missing alt text.
