Watch your machine
breathe.
System Monitor is a lightweight, always-on monitor for Linux, macOS, and Windows. CPU, memory, network, disks and processes — updated every second, docked right on your desktop.

Every vital sign, one glance away.
No dashboards to open, no commands to remember. System Monitor sits quietly and tells you exactly what your system is doing, right now.
Live CPU
Per-core load and thermals, refreshed every second — see a spike the moment it happens.
Memory & swap
Know exactly what's active, cached, and free — before swap starts working overtime.
Network throughput
Inbound and outbound traffic as a live waveform, per interface.
Disks at a glance
Capacity across every mounted drive — internal, external, or network — in one panel.
Top processes
Sorted by CPU or memory, so the runaway process is never hard to find.
Featherweight
Under 10 MB of RAM and under 1% CPU — System Monitor won't show up on its own dashboard.
Three steps, thirty seconds.
Install
One line in your terminal. No dependencies to chase down.
Launch
System Monitor docks quietly next to your system clock or in your terminal.
Watch
Live numbers update in place — no refresh, no lag, no polling.
