Glances vs mectrics
Side-by-side comparison of features, pricing, ratings, and alternatives.
Glances is an open‑source, cross‑platform monitoring tool that provides a concise, real‑time view of system resources such as CPU, memory, disk I/O, network, and processes. It runs on Linux, Windows, macOS and can be accessed via a web interface, making it ideal for both local and remote monitoring. Designed for system administrators and DevOps teams, Glances aggregates metrics into a single dashboard, supports customizable alerts, and integrates with scripts or APIs for automated workflows. Its lightweight design ensures minimal overhead while delivering comprehensive performance insights.
mectrics is a lightweight, open-source system monitor that lives in the macOS menu bar and displays real-time hardware metrics including CPU, memory, battery, network, disk, GPU, temperature, and fan speed. Users can customize which metrics are visible, set alert thresholds for specific values, and click any item to open a detailed popover showing granular data like per-core CPU load or disk throughput. A "Compact Health" mode folds the entire machine's status into a single menu bar item that stays quiet until something needs attention, and the app processes everything locally with no network requests, so nothing leaves the Mac. It is distributed under the MIT license, supports headless automation through command-line tools, and is localized into English, Turkish, Russian, Spanish, French, and Portuguese.
