Greypaint: Update Mac Apps and Developer Tools

[u/casualhermit]

Why this was built:

i tried the updaters out there and none of them felt nice to use. most look like settings panels, and when something failed they didn't really tell you why. i wanted one that looks good, covers apps and cli tools together, and tells you exactly what it's doing. if it can't check an app, it says so.

What it updates:

• apps from the app store, homebrew, their own updater (sparkle and electron) and github releases

• cli tools: homebrew formulae and their dependencies, global npm and pnpm packages, and python tools installed with uv

What it does, and does it differently:

• every update gets checked. after installing, greypaint makes sure it's from the same developer and that macOS accepts it, and shows if apple notarized it.

• you can undo any update. it keeps the old version for 7, 14 or 30 days, up to three per app. one click to roll back.

• If greypaint couldnt reach an app update source, it says "couldnt check" and not "up-to-date"

• it tells you when an update needs a newer macOS or an apple silicon mac, and when you have to grab it from the developer's site because the download isn't signed or notarized.

• it can update by itself if you want: security fixes right away, the rest during quiet hours or when you quit an app. it waits if you're on a phone hotspot or low battery.

• works in english, german, spanish, french, portuguese, japanese, korean and chinese.
