xbar for Mac

Quick summary of xbar

xbar is a free macOS utility that places script outputs directly in the system menu bar. It removes the need for extra windows or a cluttered desktop by presenting important script results where they’re always visible, helping you monitor and access key information faster.

Main advantages

• Displays outputs from a broad variety of scripts right in the menu bar.
• Lets you keep essential data in plain sight without interrupting your workflow.
• Offers a straightforward interface for organizing and displaying scripts.
• Helps automate routine checks and share quick results with minimal effort.

Who benefits most

Developers, system administrators, and other professionals who rely on small scripts to automate tasks will find xbar especially useful. It’s ideal when you want immediate visibility into job statuses, system metrics, or custom notifications without opening a terminal or separate app.

Typical uses and supported scripts

• Shell scripts, Python, Ruby, and other common scripting languages integrate easily.
• Short status indicators (CPU, memory, network), build or deployment alerts, and custom notifications are common use cases.
• You can chain scripts or create menu hierarchies so more complex workflows are accessible from a single menu item.

Quick setup tips

1. Install xbar and place script files into the designated plugin folder.
2. Ensure each script has executable permissions and a valid filename format that xbar recognizes.
3. Restart or refresh xbar to detect new or changed scripts, then customize refresh intervals and display options.

Suggested replacement: GrandPerspective (free)

If you need an alternative focused on visualizing disk usage rather than live script output, consider GrandPerspective. It’s a free macOS tool that provides a graphical overview of file and folder sizes, helping you quickly identify large items taking up space.
