gtop

A beautiful GUI system monitor built with GPUI

---

gtop is a native, GPU-accelerated system monitor that provides real-time insight into your system's performance. Built with GPUI Component — the UI framework behind Zed Editor.

Features

• Real-time CPU & Memory charts — smooth animated area charts with 120-point history
• Per-core CPU usage — color-coded grid showing individual core loads
• Process manager — sortable, searchable process table with right-click to kill
• Network monitoring — live upload/download rates
• Disk & Battery — storage usage and battery status at a glance
• CPU temperature — thermal monitoring (when sensors are available)
• Native look & feel — follows system dark/light theme, macOS-native title bar
• Smooth animations — interpolated metrics and tab transitions

Prerequisites

• Rust (edition 2024, nightly recommended)
• Platform dependencies for GPUI:
  • macOS: Xcode Command Line Tools
  • Linux: see GPUI Linux dependencies
  • Windows: Visual Studio Build Tools with C++ workload
