Wrangle features
🔁 Convert anything
Any-to-any JSON / CSV / YAML / XML with format auto-detect and documented dot-notation flatten rules for nested data.
✅ Validate & format
Pretty-print or minify JSON, YAML and XML with precise error line & column highlighting.
🔐 JWT decoder
Header/payload decode, human-readable expiry with an expired badge, optional HS256 signature verification — your token never leaves the machine.
🆚 Smart diff
Side-by-side text diff plus a JSON mode that ignores key order and whitespace, so only real changes light up.
🧪 Regex tester
Live matches with group table and replace preview — patterns run in a worker thread with a 2s timeout, so catastrophic backtracking can never hang the app.
🔏 Hash & HMAC
MD5 / SHA-1 / SHA-256 / SHA-512 of text or files — streamed, so multi-GB files are fine.
🎲 UUID, timestamps, base64, JSONPath
UUID v4/v7 in bulk, unix/ISO/local/relative time conversion, base64 + URL encoding, live JSONPath queries with a cheatsheet.
🔒 Offline by construction
The renderer's CSP is connect-src 'none' — the UI physically cannot make network requests. Zero telemetry, zero accounts.
$15 once — that's the whole pricing page
DevUtils charges $29 (macOS only) — roughly $29 a year, every year. Wrangle is a single payment, and it keeps working whether or not we ever sell another copy.
Or get Wrangle inside the full suite — every app in the catalog, currently $97 for the bundle. See the bundle →

Honest answers
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/wrangle-toolbox-mvp, and the build is genuinely trivial: npm i && npm start, zero native modules. $15 gets you the packaged installer and updates.
Why not DevUtils or DevToys?
DevUtils is polished but macOS-only — Wrangle exists largely because Windows devs kept asking for it. DevToys is free and good; Wrangle's pitch is one coherent UX across all ten tools, plus enforced guarantees like the network-blocking CSP and regex worker timeout.
How is "offline" enforced rather than promised?
The renderer ships a strict Content-Security-Policy with connect-src 'none' — outbound requests are blocked by the browser engine itself, not a privacy policy. You can verify it in the MIT source.
