Cornice vs GreatBar

Cornice is a free, open-source menu bar manager for macOS. A divider hides the menu bar items to its left, and clicking it reveals them again. An optional second divider creates a section that stays hidden even when the rest of the items are revealed. Users can adjust divider thickness and height, choose among five chevron styles, and configure keyboard shortcuts and auto-hide behavior. Cornice does not move other applications’ menu bar icons, so the divider must be positioned by hand. Optional two-finger trackpad gestures on a window title bar can resize or reposition windows, or send them to the Dock. Hiding and revealing menu bar items requires no permissions; Accessibility access is requested only when those optional gestures are enabled. The interface supports sixteen languages that can be switched without restarting. The project is distributed under GPL-3.0. It costs nothing and requires macOS 26 (Tahoe) or later on Apple Silicon. Builds are signed for development but not notarised, so macOS requires a manual first launch through its warning. After an update, gesture users must grant Accessibility permission again.

GreatBar is a free Mac app that puts shortcuts to websites, apps, files, and folders in the menu bar. Website shortcuts can open in panels that remember their size and page state, or in standalone windows that can stay above other windows. Separate browsing sessions let the same website use different logins, while private browsing keeps no cookies or history. Users can create distinct menu bars, such as work and personal setups, and shortcuts can open named macOS System Settings panes. Links for WhatsApp, Slack, Figma, Notion, Zoom, Microsoft Teams, Discord, Telegram, and Spotify can open in those apps when installed. An optional built-in MCP server lets an assistant inspect bars and propose changes for user review. GreatBar runs in the Mac sandbox and stores added files and folders as security-scoped bookmarks. It has no backend, account system, or telemetry, but its daily update check shares the user's IP address and app user agent with the hosting provider. Website views block ads and trackers by default. GreatBar requires macOS 14.0 or later.
