Listings that take over the same core job as Plasma System Monitor.

  • GNOME System Monitor

    GNOME's process viewer and resource monitor for checking CPU, memory, network and file system usage.

    FreeOpen sourceLinux

  • Mission Center

    A Linux system monitor that looks like the Windows Task Manager, which is exactly the point.

    FreeOpen sourceLinux

    Mission Center uses a Windows Task Manager style GTK4 interface with GPU usage for AMD, Intel and NVIDIA, distributed as AppImage and Flathub.

  • Resources

    A GNOME app that shows CPU, memory, GPU, network, storage and battery usage and manages processes.

    NeoHtop is an MIT-licensed desktop process monitor that also runs on Windows and macOS, with CPU and memory views and process search.

  • htop

    Interactive process viewer for the terminal.

    FreeOpen sourcemacOSLinuxCommand line

    htop is a terminal process viewer for killing, renicing and filtering processes, with no historical graphing or sensor pages.

  • btop++

    A terminal resource monitor that looks good enough to leave open, with processes, CPU, memory, disks, network and GPUs.

    FreeOpen sourcemacOSLinuxCommand line

    btop moves monitoring into a terminal, adding GPU graphs and working over SSH, and also runs on macOS.

  • bottom

    A graphical system monitor for the terminal, with charts for CPU, memory, network, temperature and disk over time.

    FreeOpen sourceWindowsmacOSLinuxCommand line

    bottom is an MIT-licensed terminal monitor charting CPU, memory, network, temperature and disk over time on Linux, macOS and Windows.

  • Glances

    A cross-platform system monitor that runs in a terminal, in a browser, or as an API feeding a dashboard.

    FreeOpen sourceWindowsmacOSLinuxCommand lineWeb

    Glances runs in a terminal or browser across Linux, macOS and Windows, and also monitors Docker and Podman containers.

Also worth comparing

These listings name Plasma System Monitor as their own alternative, so the relationship runs both ways.

  • lm-sensors

    Linux command-line utilities and a library for reading hardware temperature, voltage and fan sensors.

    FreeOpen sourceLinuxCommand line

    Plasma System Monitor shows sensors in a graphical KDE window alongside processes and resource usage, and fits best on a Plasma desktop.
