Last two weeks my feed has been full of macOS utilities people built and now sell for $5-10 each. And honestly, I don't get it.
Would you pay $5 for a better Activity Monitor?
I wouldn't.
Not because it's bad or useless, but because today you can build one yourself in a few hours with your AI subscription. You make it exactly the way you want, and if you open-source it, other people can make it even better.
A good example of this is Vorssaint, a free, open-source bundle of genuinely useful tools for Mac users.
So I built two of my own.
OpenDoc is a replacement for the macOS Dock with custom widgets, folders and a lot more things you've probably wanted your Dock to do.
OpenActivity is a better Activity Monitor, built to make monitoring your Mac simpler.
Both are native, written in Swift, and fully open source. Stars, issues and PRs are welcome.
