DevUtils deserves real credit: it popularized the idea that developer utilities — JSON formatting, JWT decoding, regex testing — should be a fast native app on your machine, not a grab-bag of ad-covered websites you paste production secrets into. It is polished, it is offline, and its one-time pricing respects its users.
It is also macOS-only. If you are on Windows, DevUtils simply is not an option, and the usual fallback is right back to jwt.io and random web formatters. Wrangle is the same philosophy built for Windows first: ten offline data tools in one desktop app, zero network calls enforced at the CSP level, $15 once. Here is how they honestly compare.
What DevUtils does well
DevUtils gets the fundamentals right:
- Genuinely offline — your tokens, keys and customer data never leave the machine.
- Big tool coverage — 45+ utilities, more than most people will ever open.
- Native macOS polish — fast launch, smart clipboard detection, deep system integration.
- One-time pricing — around $29 for a license; no subscription, which is rare and commendable in this category.
If you are on a Mac, DevUtils is an easy recommendation and this post will not talk you out of it.
Where the subscription model hurts
The dealbreaker is simple: there is no Windows version, and none is coming — DevUtils is built on native macOS frameworks. The half of the developer world on Windows gets the worst of both worlds: aware of the secrets-in-websites problem, with no equivalent app to fix it. He3, the main cross-platform option, went subscription at $9.90/month — $118 a year for a JSON formatter.
The deeper issue both fix — and web tools never will — is worth restating: every JWT you paste into jwt.io, every customer record you drop into a "free JSON formatter", travels to a server you know nothing about, next to ads and trackers. It works until the day the token in your clipboard is a production token. That is not a hypothetical; it is a Tuesday.
Wrangle: the pay-once alternative
Wrangle is a $15, one-time purchase. The offline developer data toolbox. Stop pasting API keys into random websites. Wrangle packs the ten tools developers actually open daily: any-to-any JSON/CSV/YAML/XML conversion, validate/format with exact error line and column, JSONPath queries, smart JSON diff that ignores key order, JWT decode with expiry badge and HS256 verification, base64/URL encoding, MD5-SHA512 + HMAC hashing that streams multi-GB files, UUID v4/v7 bulk generation, a regex tester with a 2-second catastrophic-backtracking kill switch, and timestamp conversion. Drag-drop everywhere, Ctrl+K palette, MIT source, $15 once.
The source code is MIT-licensed at github.com/bensblueprints/wrangle-toolbox — free to build and run yourself, forever. Buying the packaged version on Whop gets you the signed installer, 1-click setup and updates. Either way, there is no account, no telemetry and no renewal date.
Head to head

| Price | $15 once | ~$29 one-time license |
| Cost over 3 years | $15 | License (+ paid major updates) |
| Where your data lives | Your machine / your server | Local |
| Usage limits | None — unlimited use | macOS only — no Windows version |
| Works offline | Yes | Yes |
| Source code | MIT, on GitHub | Closed |
Who should stay with DevUtils
Stay with DevUtils if you are on macOS — it is mature, broad and fairly priced, and Wrangle does not run there today. This is the rare comparison where the answer is mostly your operating system.
Switch if you are on Windows, or if you want the tighter, cheaper take: ten high-frequency tools with one coherent UX for half the price, with the no-network guarantee enforced in code (the renderer's CSP is connect-src 'none') rather than promised in a privacy policy.
Making the switch
Step 1 — Buy once on Whop. One-time $15 — the cheapest tool in the suite, and probably the one you'll open most days.
Step 2 — Install in one click. Signed Windows installer, no native modules, nothing to compile. Dark mode by default.
Step 3 — Hit Ctrl+K. Ten tools one keystroke apart, drag-drop files into any input, copy button on every output, per-tool local history.
Common questions
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/wrangle-toolbox, 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
Subscriptions make sense when a service does ongoing work for you — hosting, syncing, multi-region infrastructure, human labor. They make much less sense when the work happens on your own hardware and the monthly bill is just a toll booth. Wrangle is our bet that for this job, most people are better served owning the tool: $15 once, 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.
Wrangle is part of OneTimeSuite — 56 desktop and self-hosted apps built on the same principle: your hardware does the work, so you should not pay rent on it. Every app is a one-time purchase with MIT-licensed source on GitHub, no accounts and no telemetry. Want everything at once? OneTimeSuite Complete bundles the whole suite for a single flat $997.
