About QAKit Toolbox
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.
