Overview
Offline toolbox for developers & QA: JSON, YAML, JWT, regex, hashes, passwords, color picker, screenshots and more.
QAKit Toolbox is a single side-panel home for the small utilities every QA engineer and web developer reaches for ten times a day — without leaving your browser and without sending your data anywhere. New in 0.2.0: Password Generator and a JSON → YAML converter, plus a rebuilt Screenshot editor with blur, step numbers, emoji stamps, curved arrows, and full undo/redo. Thirteen tools, zero network calls: • JSON Formatter — format, minify, validate, and query with JSONPath (with autocomplete) • JWT Decoder — split, decode, and check expiry/not-before of JSON Web Tokens • Base64 / URL — encode and decode, with auto-direction detection • Unix Timestamp — convert between epoch and human-readable dates, any timezone • UUID Generator — v4, v7 and NIL, batch generation • Regex Tester — live match highlighting, capture groups, full cheatsheet • Hash Calculator — MD5, SHA-1, SHA-256, SHA-512, for text or files • Text Diff — side-by-side and unified, ignore whitespace/case • Clipboard History — auto-capture, search, pin important items • Color Picker — pick any color on screen, copy as HEX/RGB/HSL • Screenshot — capture the active tab, annotate with rectangles, highlights, arrows, lines, freehand pen, multi-line text, crop • Password Generator — strong random passwords with length, character-set, and exclusion rules • JSON to YAML — convert JSON to YAML, copy or download the result Built for QA workflows: 6 languages · light/dark/system themes · persistent history that survives Chrome restarts · keyboard shortcut anywhere · export/import settings as one JSON file. Privacy first: Everything runs locally. No analytics, no telemetry, no servers. No upsells, no accounts, no tracking.
