This is a project I've been working on since I became unemployed. As I developed the app, I learned Swift along the way. Not only did it help me master Swift development, but I also created an app that can perform various tasks without relying on online tools, such as SSL management, image watermarking, NPM statistics, URL decoding, and more.

The app runs entirely offline. You can check it out here: https://github.com/jaywcjlove/DevHub

To keep DevHub healthy and well-maintained, I accept donations as a way to generate some income and continue working on it. The app is almost free, and if the tools don't meet your needs, feel free to email me. I’d be happy to hear your ideas and possibly develop small tools for you at no cost.
