System Monitor

A glance tool, not a process manager. The computer feels slow — open this, see which application is hot, close it. CPU, memory, storage, Docker images, GPU. Calm by design.

Features

One glance. The answer.

Five tabs

CPU, Memory, Storage, Docker, GPU

Each tab is a single calm view of one resource. No 400-row process table, no graphs wall.

Live

2s refresh

CPU and Memory update every two seconds. GPU utilization too, when an NVIDIA card is detected.

Quiet quit

Hover a row, click the X

Sends SIGTERM to every process in the group with a confirm. The system shell is still the escalation for force-kill.

Drill-down

Where is the disk going?

One click into Pictures, Cache, .local/share, then deeper. Bars show share of disk; Open jumps to the file manager.

Calm

Three-state traffic light

A single colored dot per row tells you whether anything's hot. No 12-line summary, no notifications.

Native Linux

Small binary. Real .desktop entry. AppImage and .deb. No Electron.

Krill principles

A simple interface.

Focus One app, one job. One file, one window. No tabs, no project trees, no mode pickers — the work in front of you is the work.

Beauty A locked palette, careful typography, chrome that sits still. The apps shouldn't be the part of your desktop you have to forgive.

Simplicity No settings panel, no plugin system, no power-user knobs. If a feature can't be explained in a sentence, it doesn't ship.

Ownership Your files on your disk in their original format. No accounts, no cloud, no telemetry. MIT licensed; build it yourself if you don't trust ours.

Install

Quick install

One-liner — downloads the AppImage to ~/.local/bin, marks it executable, and registers a launcher entry. Re-run to upgrade.

curl -fsSL https://krill-software.github.io/install.sh | bash -s system-monitor

Download .deb

# install with apt
sudo apt install ./System.Monitor_0.2.0_amd64.deb
