689 Open Source macOS Apps: Your New Discovery Playground
If you're a macOS user who loves open source software, you've probably spent hours searching for that one app that does exactly what you need but doesn't cost a thing. Or maybe you're a developer looking for a solid codebase to learn from or contribute to.
Either way, I found something today that might save you a lot of time. There's a GitHub repository that curates 689 open source macOS apps across 49 categories. Yes, 689, and they're all real, usable apps.
What It Does
The repo is a simple list. No fancy frontend, no search engine. Just a well organized Markdown file that groups macOS apps by category. Each entry links directly to the app's GitHub repository or website. Categories range from "Audio" and "Developer Tools" to "Games", "Productivity", "Editors", and even "Utilities".
It's like a directory of everything you might want to build or use on macOS, all open source. No curation fluff, just the straight link and a short description.
Why It's Cool
A few things stand out.
First, the sheer variety. You'll find everything from popular apps like iTerm2 and Visual Studio Code to niche tools like a tiny app that displays a menubar countdown to your next event. There's an app for screenshot editing, terminal-based file managers, email clients, and even a macOS version of the classic game "Asteroids".
Second, this list is a goldmine for developers. If you're learning Swift or Objective-C, picking an app from here and reading its source code is like getting a free tutorial. You can see real patterns, real architecture, and real solutions to common macOS problems.
Third, it's community maintained. The repo has over 1,000 stars and active contributions. That means the list stays fresh. New apps get added, old ones get removed if they break.
Finally, it's not just for Mac beginners. Even if you've been on macOS for years, I guarantee you'll find at least three apps you've never heard of but now desperately want to try.
How to Try It
There's no installation. Just open the repository:
https://github.com/serhii-londar/open-source-mac-os-apps
Scroll down to the "Applications" section. Pick a category that interests you. Click any link. That's it. If an app looks promising, clone the repo or download a release build.
You can also star the repo on GitHub to bookmark it, or even open a PR if you have another open source macOS app to add.
Final Thoughts
This isn't a flashy tool. It's a list. But it's a really good list. If you're a developer who uses macOS, this repo is like a library of blueprints. You can study them, modify them, or just use them as they are.
The best part? It reminds me that the open source ecosystem on macOS is way bigger than I thought. So many people build things just for the love of it. That's kind of cool.
