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-smisubprocess)
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 |

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