GT-STACER is a graphical system monitoring and optimisation application for Linux. It is a modernised fork of Stacer, rebuilt using Qt 6 and C++17 to provide an integrated environment for monitoring resources and administering a Linux system.
The application presents processor activity, memory consumption, disk utilisation and network traffic through an interactive dashboard. It also displays information about graphics hardware, temperatures and battery status where supported.
Beyond monitoring, GT-STACER brings together utilities for managing processes, services, startup applications and system maintenance. Additional tools cover network connections, firewall configuration, power management and data recovery.
The interface includes a collapsible sidebar, system tray integration, configurable themes and multilingual support.
This is free and open source software.
