Project
Pensol
An animation app for bringing drawings and ideas to life—without needing a giant, confusing animation studio.

Hi, I’m King Mustard.
I make macOS apps, games, and whatever other ideas escape my brain. I’m the developer behind BrewMate—and yes, I somehow got a domain for all of this.
Try: brew install air
$
Stuff I made.
Useful apps, games about dogs, and projects that started with “wait, what if…”
macOS app
BrewMate
A clean, native way to install Homebrew, browse packages, update everything, and KILL—sorry, uninstall—packages.
Game
Rudi Foodi
A giant browser game starring Rudi, treats, Zoomies, boss fights, and a completely reasonable amount of chaos.
Project
Yankr
Another King Mustard creation, built from one of those ideas that was too interesting to leave sitting in my brain.
macOS
HapticPad
A haptic-powered trackpad experiment for macOS, built to make the trackpad do way more interesting things.
Project
Roku Train
A project involving Roku and, as promised by the name, trains. Technology has peaked.
Native on purpose
BrewMate was built specifically for macOS, so it feels at home next to the apps already on your Mac.
Made to be useful
The goal is simple: make Homebrew less confusing without taking away what makes Homebrew great.
Built by curiosity
I make apps, games, and other things mostly because I wonder, “Could I actually build that?” Usually, yes.
“I made BrewMate because I was bored.”
Possibly the greatest product strategy ever invented*
