Alternatives to Resources
A GNOME app that shows CPU, memory, GPU, network, storage and battery usage and manages processes. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
Resources
A GNOME app that shows CPU, memory, GPU, network, storage and battery usage and manages processes.
Replacements
Listings that take over the same core job as Resources.
GNOME System Monitor
GNOME's process viewer and resource monitor for checking CPU, memory, network and file system usage.
GNOME System Monitor is the desktop's standard task manager with CPU, memory and network graphs and process control, but offers less detail such as GPU and battery readings.
Mission Center
A Linux system monitor that looks like the Windows Task Manager, which is exactly the point.
Mission Center uses a Windows Task Manager style layout with GTK4, covers AMD, Intel and NVIDIA GPUs, and is packaged as AppImage and on Flathub.
Plasma System Monitor
KDE's desktop application for monitoring system sensors, running processes and resource usage on Linux.
Plasma System Monitor is KDE's equivalent with customizable monitoring pages for sensors and processes, and fits a KDE Plasma desktop better than GNOME.
NeoHtop
Inspect running processes in a desktop system monitor.
NeoHtop is a desktop process monitor with search and filtering that also runs on Windows and macOS, but focuses on CPU and memory rather than GPU or battery.
btop++
A terminal resource monitor that looks good enough to leave open, with processes, CPU, memory, disks, network and GPUs.
btop++ moves monitoring into a terminal, with process management, CPU, memory, disk, network and GPU graphs, and runs over SSH on Linux and macOS.
Also worth comparing
These listings name Resources as their own alternative, so the relationship runs both ways.
Astra Monitor
A GNOME Shell extension that shows processor, GPU, memory, storage, network and sensor readings in the panel.
Resources is a GNOME app covering CPU, memory, GPU, network, storage and battery in a separate window, and it can also manage processes.
