macnetmon
Network interface bandwidth monitor for macOS
 |
 |
| Split RX/TX view | Total view |
About
macnetmon is a TUI (Terminal User Interface) application that displays real-time network interface bandwidth usage on macOS. It monitors incoming (RX) and outgoing (TX) traffic rates for all network interfaces with colorful visualizations.
Inspired by macmon, which monitors Apple Silicon power consumption.
Features
- Real-time network bandwidth monitoring
- Split sparkline visualization for RX/TX traffic
- Multiple color themes (7 solid colors + 10 advanced themes including Catppuccin, Dracula, Nord, Tokyo Night)
- Friendly interface names from macOS
networksetup - Toggle display of loopback, virtual, and inactive interfaces
- Sort by bandwidth or interface name
- Overview panel showing total system bandwidth
- Bits/s and Bytes/s display modes
- Persists settings (theme, toggles, interval) across runs
- 512-sample history depth
Installation

Configuration
macnetmon persists settings to:
~/.config/macnetmon.json
CLI flags override saved settings for that run, and the updated values are saved back to the config.
Default interval is 1000ms if no config exists.
Requirements
- macOS (uses macOS-specific APIs via libc)
- Rust 1.70+ (for building from source)
