Xbar

xbar displays the output of any executable script or program directly in the macOS menu bar, providing a lightweight way to monitor information at a glance. Users can install pre‑built plugins that cover a wide range of topics such as network status, cryptocurrency prices, battery levels for Bluetooth devices, RSS feeds, and miner statistics. Each plugin runs the underlying script and renders its result in the menu bar, allowing quick access without opening separate applications.

The tool is open‑source and freely available, targeting developers and power users who want to customize their desktop with real‑time data from arbitrary command‑line utilities. Plugins can be written in any programming language, and the community contributes a growing collection organized by category, including cloud services, finance, weather, and more.

xbar functions as a modern replacement for BitBar, offering a stable, mature implementation that integrates seamlessly with macOS and supports user‑maintained extensions through a simple plugin architecture.
