rproc

rproc is a lightweight Linux resource and process monitor inspired by the Windows 11 Task Manager. Built with Rust and the Slint UI framework, it offers real-time monitoring of CPU (global and per-core), memory, disk I/O, network, and GPU (NVIDIA/AMD/Intel). Features include process management with sorting, filtering, and kill capabilities, live performance charts, per-process graph attribution, startup app management, systemd service monitoring, and customizable settings. It is designed to be memory-efficient, using only ~25 MB with GPU monitoring off and ~45 MB with it on, significantly less than alternatives like GNOME System Monitor or Mission Center. rproc supports multiple installation methods including .deb, .rpm, Flatpak, AppImage, Nix, and AUR packages.
