GPUvisor

A lightweight system tray app for monitoring NVIDIA GPUs on Linux.

Features

• System tray with live GPU stats (configurable: utilization, temp, memory, power, fan)
• Detail panel — frameless popover with per-GPU cards showing all metrics in real-time
• Process list — see which processes are using each GPU
• Multi-GPU — show all GPUs, a single GPU, or aggregate stats
• Settings — choose inline metrics, temperature unit (C/F), poll interval
• Lightweight — ~3 MB .deb, polls via NVML (no nvidia-smi subprocess)

Metrics

Metric	Inline	Detail Panel
GPU Utilization	Yes	Yes
Temperature	Yes	Yes
Fan Speed	Yes	Yes
Memory Usage	Yes	Yes (with bar)
Power Usage	Yes	Yes (with bar)
Clock Speeds	—	Yes
Processes	—	Yes

Install

From .deb (Ubuntu/Debian)

sudo apt install ./GPUvisor_0.1.0_amd64.deb

From .AppImage

chmod +x GPUvisor_0.1.0_amd64.AppImage
./GPUvisor_0.1.0_amd64.AppImage

Runtime dependencies

• NVIDIA drivers (provides NVML)

Tech Stack

• Tauri v2 — system tray, webview window
• Rust — backend, GPU polling via nvml-wrapper crate
• NVML — NVIDIA Management Library (direct GPU access, no CLI parsing)
• Vanilla JS/CSS — frontend, no framework
