PCHardwareTest is a free browser-based toolkit for checking everyday PC hardware without installing software. Test keyboards, mice, webcams, microphones, speakers, headphones, screens, gamepads, touch devices, battery status, network information, and browser-reported system information. It stands out by clearly showing what the browser can actually detect instead of claiming low-level hardware diagnostics it cannot perform.

Hey Product Hunt! 👋 I built PCHardwareTest because sometimes you just want to quickly check whether a keyboard, mouse, webcam, microphone, speaker, screen, or controller is actually responding without installing another utility. The project runs directly in the browser and also includes browser-reported system information such as logical CPU cores, approximate device memory where supported, screen resolution, viewport size, touch capability, and browser details. One thing I tried to get right is being honest about browser limitations. It shows what the browser can actually access instead of pretending to perform low-level hardware diagnostics. What hardware test or troubleshooting feature would you add next?
