Show HN: Updater – one command for macOS app updates
zhengda-lu Sunday, March 01, 2026
I built updater to solve a small but annoying problem: macOS app updates are fragmented across different systems.
updater scans installed apps, determines where each app should be checked (Sparkle, Homebrew casks/formulae, Mac App Store via mas, GitHub Releases, and macOS system updates), then runs source specific update actions from the terminal. It also has an interactive TUI (run `updater` with no args).
A few commands:
updater check updater update --all updater update "1Password"

Would love feedback, especially on reliability and edge cases.
Summary
The article introduces an open-source software updater called Updater, which allows developers to easily add automatic software updates to their applications. Updater provides a simple and secure way to check for, download, and install updates, making it a convenient tool for keeping software up-to-date.
