HardwareVisualizer is a free, open-source, cross-platform hardware monitoring tool. It lets you track CPU temperature, GPU usage, memory allocation, and system performance in real-time with beautiful graphs and minimal system impact.

Yes, HardwareVisualizer is completely free and open-source under the GNU General Public License v3.0 or later (GPL-3.0-or-later). Versions released before the relicense remain available under the MIT license. Download it only from hardviz.com, GitHub Releases, or Winget on Windows where available; third-party mirrors, file-sharing links, YouTube description links, and password-protected archives are not official.

HardwareVisualizer supports Windows 10, Windows 11, macOS (Apple Silicon officially supported, Intel experimental), and major Linux distributions (Debian/Ubuntu, RPM-based distros, AppImage).

HardwareVisualizer is designed to be lightweight with a modern UI. Unlike Task Manager, it provides detailed graphs and configurable long-term history, kept for 30 days by default and extendable in settings. It pauses hidden-window updates while in the system tray, and the interface stays customizable.

Yes! HardwareVisualizer runs in the background with minimal resource usage, making it perfect for monitoring CPU usage and memory during gaming sessions. GPU temperature monitoring is fully supported on NVIDIA GPUs, with partial support for AMD and Intel GPUs. You can also check historical data to see how your system performed.

HardwareVisualizer fully supports NVIDIA GPUs. AMD and Intel GPUs are partially supported — core metrics such as usage and temperature work, though some readings may be limited or less accurate.

Absolutely! You can request new hardware support, themes, languages, and other features by creating an issue on GitHub. Contributions are always welcome — feel free to submit pull requests or join the discussions.
