    OpenHardwareMonitor

    OpenHardwareMonitor

    Free open source tool for real-time PC hardware sensor monitoring

    Open Hardware Monitor is a free and open source hardware monitoring application designed primarily for personal computers. It provides real-time insights into key system metrics such as temperatures, fan speeds, voltages, load percentages, and clock speeds by reading directly from sensors embedded in CPUs, GPUs, motherboards, and storage devices. The tool supports a wide range of sensor hardware found on modern systems, including Intel and AMD processors, NVIDIA and AMD graphics cards, SMART temperature sensors on storage drives, and many motherboard monitoring chips. Users can view monitored data directly within the application, as customizable desktop gadgets, or through a system tray interface, making it easy to keep an eye on system health at a glance. OpenHardwareMonitor runs without the need for a traditional installation (it can be run portably) and on systems configured with the appropriate runtime (e.g., .NET or Mono).

    OpenNetMeter

    OpenNetMeter

    A simple program to monitor your network/data usage

    OpenNetMeter is a Windows desktop application intended for monitoring network traffic and data usage at the system and per-process level. It features a user-friendly interface that displays upload and download speeds in real time, along with a history of data consumption for the current session, and aggregates totals since launch or last reset. The app also breaks down usage by process, giving you visibility into which applications are consuming network bandwidth. It lives in the system tray, making it accessible and minimally intrusive for everyday use. Since it's open-source, users can inspect how data collection is done and trust that it’s not sending data elsewhere. While still evolving, it serves a practical niche for users who want more transparency than what built-in OS tools provide.

    CapFrameX

    CapFrameX

    Frametime capture and analysis tool

    CapFrameX is a performance capture and analysis tool designed for PC gamers and benchmarking enthusiasts, which records frametimes, frame-rates and various sensor data during game or application execution. It uses backend tools like PresentMon to log data and then exposes a comprehensive UI for analyzing the results: you can view charts of frametimes, historic graphing, stuttering analysis, L-shape graphs, input-lag overlays, and compare multiple capture runs side by side. Importantly, the tool also integrates with sensor inputs (CPU, GPU, VRAM, temps, etc.) and overlays statistics in-game via Rivatuner Statistics Server, so you get in-situ feedback while you run. For benchmarking, it supports aggregation, filtering, outlier detection, and export of records to CSV/Excel for further analysis or reporting. The project is suited for reviewers, hardware testers, and power users who want to dig deeper than simple FPS numbers and want to diagnose performance issues.
