Pawvis is an open source Mac app that reads your hand through the webcam, so you raise it and the cursor follows, dip a finger to click, hold it to drag, fold two to scroll. Alexandria Redmon built it because she wanted to use a computer the way films have been showing it for decades, and none of what the camera sees ever leaves the machine.

Port Radar sits in your Mac menu bar listing whatever is holding each port, then tells you in plain English what the process actually is and whether stopping it will break anything, which Apple Intelligence works out on the device. Sebastian Solano built it because something was always already on port 3000 and he never knew what, which he describes as his entire week, every week. It'll open a Cloudflare tunnel over a local site too, if you want to show someone.

Toplify tracks where your app is placing in the App Store across 175 countries without an API key or App Store Connect access, so you paste a name or a link and it just starts watching. It pings you when the app turns up somewhere you weren't expecting, and translates the reviews coming in from languages you don't read. Dmytro Chuta built it for his own apps and left it free for anything that isn't charting yet.
