PayloadIQ is a free, browser-local toolbox that runs on any operating system with nothing to install; DevUtils is a paid, native macOS app that works fully offline. Both are built around the same promise — your data stays on your machine — so the decision comes down to platform, price, and what each one focuses on.

When DevUtils is the better fit
If you're on a Mac and want a polished native appthat lives in your menu bar, launches instantly, and works with zero network even on a fresh boot, DevUtils is a lovely piece of software with a wide set of utilities and a one-time price. A native app can also integrate with the OS in ways a web page can't.
Where PayloadIQ goes further
PayloadIQ is free and runs anywhere a browser does — Windows, Linux, macOS, a locked-down work laptop, a Chromebook — with nothing to download. Beyond the shared utilities, it adds the API-payload playground (types, Zod, Prisma, a typed client, schema-quality and breaking-change reports) and document-to-Markdown converters for LLM context. Once a page has loaded, it keeps working offline too.
The short version
Pick DevUtils if you want a paid native Mac app and never leave macOS. Pick PayloadIQ if you want a free, cross-platform toolbox in a browser tab, plus the payload-to-code workflow on top.
