Every developer has pasted a JWT full of production credentials into jwt.io, or dropped customer JSON into an ad-covered "free formatter". DevUtils fixes that — but it's $29 and Mac-only. He3 wants $9.90/month. Wrangle packs the 10 highest-frequency data tools into one fast desktop app that physically cannot make network requests, for $15, once.
If you've searched for a DevUtils alternative, Wrangle is the pay-once option worth putting at the top of the list: Wrangle is $15, one time, and covers the same core job DevUtils charges $29 (macOS only) for.
What makes Wrangle the pick for 2026
- 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.
Wrangle vs DevUtils, at a glance
| Wrangle | DevUtils | |
|---|---|---|
| Price | $15 once | $29 once |
| Windows | Yes (Windows-first) | No — macOS only |
| Your data stays on your machine | Yes, always | Yes |
| Works offline / behind a corp proxy | Yes | Yes |
| Regex DoS protection (worker + timeout) | Yes | Unknown |
| Ctrl+K command palette + drag-drop | Yes | Yes |
| Subscription required | Never | Never |
| Source code | MIT, on GitHub | Closed |
Half the price of DevUtils, and it runs on Windows. Against He3's $9.90/month it pays for itself in under 2 months — a year of He3 costs nearly 8x Wrangle.
Common questions
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.
The bottom line
Wrangle won't out-feature DevUtils on every axis — no subscription tool with a bigger team and a bigger roadmap loses on everything. But for the core job, $15 once against $29 (macOS only) forever is a trade most people should at least look at. Wrangle is part of OneTimeSuite, a catalog of pay-once apps that replace subscription SaaS.
