Hidden Bar vs SwiftBar

Hidden Bar is a free, open-source macOS app for hiding menu bar items. Click its arrow to expand or collapse the hidden section, and Command-drag icons across the divider to choose which items it hides. Preferences include automatic re-collapse after a selected delay and a system-wide shortcut. An optional second section stays hidden even when the main section is expanded; Option-click the arrow to reveal it. The app can launch at login through the macOS 13 or later SMAppService login item. It is available through Homebrew or manual download, and the project describes its direct download as notarized. The listed plan is free. On macOS 27, the direct download requires Accessibility permission to detect icon positions; hiding is per app, built-in macOS items remain visible, and the app must run from /Applications. That hiding feature relies on a private Apple framework that a macOS update could disrupt.

SwiftBar displays the output of custom scripts in the macOS menu bar and turns it into interactive menus. Plugins can be written in Bash, Python, Ruby, Swift, or JavaScript; SwiftBar runs them on a user-defined schedule and builds menu items from their output. Menus can include icons, colors, dropdowns, submenus, and click actions. Items can open URLs, run shell scripts, refresh plugins, or use keyboard shortcuts. Refresh intervals can be set in plugin filenames or with cron syntax in metadata. SwiftBar includes a plugin repository through its Get Plugins menu, and its product page describes hundreds of community-created plugins. Its plugin API is adopted from BitBar, allowing existing BitBar and xbar plugins to run. SwiftBar also supports plugins made with the macOS Shortcuts app and provides a settings interface for their refresh schedule. It is a free, open source project by Ameba, licensed under MIT. SwiftBar requires macOS 12 or later and is available as a direct download or through Homebrew.
