I built a calm, readable system monitor for Linux (Qt6, C++20, open source)

Most Linux system monitors end up in one of two places: they feel ancient and cramped, or they show everything at once and become visual noise. I wanted something in between, genuinely useful but still pleasant to look at for more than ten seconds. So I built archvital.

It has a compact Overview page for the numbers that matter most, plus dedicated pages for CPU, GPU, Memory, Disk, Network, Tasks, and a Diagnostics page for common health checks. There is a Settings page for theme colors and section visibility, and preferences are saved through QSettings so the app remembers your layout between sessions.

The whole thing is built on Qt6 and C++20 with custom sidebar, card, sparkline, and bar components. No extra widget library beyond Qt itself.

The project is already daily driveable but still actively evolving. Screenshots are in the repo. If you try it and something looks wrong or reads oddly, that is exactly the kind of feedback I am looking for.
