Matterhorn for Mac

Terminal-based client for Mattermost

Matterhorn is a free Unix terminal application built to let users access Mattermost from the command line. It provides a compact, text-only interface for reading and sending messages, tracking channels, and receiving alerts — ideal for people who prefer keyboard-driven workflows instead of graphical apps.

Primary capabilities

• Fast startup and low memory use for snappy interactions.
• Compose and deliver messages, as well as receive incoming posts.
• Manage channels, mentions, and notification settings right from the terminal.
• Browse conversation history and monitor team activity without switching to a GUI.
• Simple controls that make it straightforward for developers and power users to incorporate into daily routines.

macOS compatibility and workflow fit

Matterhorn runs on Unix-like systems and can be used on macOS, so it can slot into existing Mac-based workflows without much setup. Its minimal footprint and responsive behavior make it a practical choice for teammates who want to stay connected to Mattermost while working in terminals, editors, or remote shells.

When you might prefer a different tool

If your needs extend beyond a terminal client — for example, graphical device management or iOS data recovery — you might consider a dedicated macOS application instead. One option available with a trial for macOS is MobiKin Doctor for iOS, which focuses on device-level tasks rather than chat access.
