DevToys for Mac is the developer utility app that quietly replaces a dozen browser tabs and online tools you probably have bookmarked for converting, formatting, and encoding things during your daily development work. Version 2.0 brings the most significant expansion yet with new tools, a redesigned interface, and cross platform support that makes it genuinely useful across every machine in your workflow.
I keep it open constantly because having every common developer utility in one fast native app is something that saves more time than you realize until you try doing without it.On the AI assisted coding side, I’ve also been leaning on Repo Prompt for Mac lately for pulling relevant context together before handing anything off to an LLM, and the two end up complementing each other nicely in day to day work.
DevToys Overview
DevToys for Mac is a native developer toolbox that bundles a large collection of commonly needed utilities including JSON formatters, encoding and decoding tools, diff checkers, hash generators, and much more into one clean and offline capable application. Everything runs locally on your Mac without sending anything to an external server which matters when you’re working with sensitive code or data. DevToys for Mac is the Swiss Army knife that lives in your dock rather than scattered across twenty different websites.
Developers who also need a lightweight local server for testing their web projects without any complex configuration will find SwiftServer for Mac a natural companion, spinning up a local HTTP server in seconds from the menu bar without touching the terminal.

Why Use DevToys for Mac?
What makes DevToys for Mac genuinely worth having as a permanent fixture in your workflow is the combination of breadth and speed. Every tool you reach for regularly during development is already there and opens instantly without a browser tab, an ad, or a privacy concern about what you’re pasting into an online tool.
The JSON formatter alone saves the kind of time that adds up significantly over a week and having the diff checker, regex tester, and hash generator all in the same place means you’re never context switching just to use a basic utility.
Developers who want a clean visual Git client to manage the repositories they are working on alongside DevToys will find Gitfox for Mac a natural addition, making branch management, commits, and code reviews far more intuitive than working through the terminal alone. For any developer working on a Mac who wants their most used tools consolidated into one fast and offline capable app, DevToys for Mac makes a lot of sense.
