LibreHardwareMonitor/LibreHardwareMonitor

Libre Hardware Monitor is a system monitoring application that collects and displays telemetry from various computer components. It provides detailed metrics for CPUs, GPUs, memory, storage, and power supplies, alongside support for external cooling controllers and network interfaces. The system has been modernized to support multiple .NET versions and platforms, replacing legacy drivers with a modular architecture for hardware detection and sensor management.

How it got here

2010 · Legacy code and dependency cleanup

This period focused on modernizing the codebase by removing obsolete hardware monitoring interfaces, legacy GUI components, and outdated utility classes. The project was also renamed to Libre Hardware Monitor and migrated to modern .NET SDK-style project files with updated dependencies.

14 changes

2019 · Hardware monitoring architecture refactoring

This period focused on a comprehensive architectural overhaul of the hardware monitoring library, introducing modular, vendor-specific implementations for CPUs, GPUs, memory, and storage. The changes standardized internal interfaces and abstractions to improve extensibility and cross-platform support, while adding detailed sensor data for network interfaces and various hardware controllers.

12 changes

2020–2025 · Hardware monitoring expansion and driver modernization

This period focused on significantly expanding hardware support for various cooling, power, and battery devices, while simultaneously modernizing the underlying architecture. The codebase migrated from WinRing0 to the PawnIO driver for improved compatibility and added ARM64 platform support, alongside refactoring the Embedded Controller system to support ChromeOS.

10 changes

2026 · New hardware support and UI updates

This period focused on expanding hardware compatibility by adding support for ARCTIC fan controllers, Thermal Grizzly power monitors, and MSI AIO coolers, each introducing new sensor and control classes. Additionally, the embedded web server and UI assets were updated to improve the web-based sensor display.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 5 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit d6cb260464 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
