Everyday developer helpers

I want to pick an open-source project for small tools: format json, decode tokens, convert text. Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - DevToys: DevToys is a desktop app with a bundle of small tools that help with everyday computer tasks like formatting data, decoding text, and converting files. It is aimed at programmers and people who work with technical data. [Easy setup; Windows · Mac · Linux; replaces fully; MIT; https://github.com/DevToys-app/DevToys] - CyberChef: CyberChef is a web app that lets you transform and inspect data, such as decoding text, encrypting it, or calculating checksums, all inside your browser. It is mainly for technical people and analysts who work with data, though the README says it is also designed to be usable by non-technical people. [Easy setup (It is a website: you use it in a browser with nothing to install.); In your browser; replaces fully; Apache-2.0; https://github.com/gchq/CyberChef] - IT-Tools: IT-Tools is a collection of small online helper tools, such as formatting text data, decoding tokens and converting values. It is made for programmers and people who work in IT, and it can also be run on your own server. [Easy setup; In your browser; replaces fully; GPL-3.0; https://github.com/CorentinTh/it-tools] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/dev-toolbox.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/dev-toolbox.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
