Hardware & Display Diagnostics
Run physical-world hardware and display tests directly in your browser. Verify monitor pixels, webcam lighting, and input lag locally. Start testing now.
Why run hardware tests locally?
Cloud benchmarks and remote testing services can measure general performance, but they cannot test the physical display in front of you. Dead pixels, backlight bleed patterns, and motion ghosting are properties of your specific panel, and a remote server cannot see them. Browser-based hardware tests close that gap: they run fullscreen on your actual hardware, using only the APIs your browser exposes.
The Web Performance API gives sub-millisecond resolution for input latency measurements that would be meaningless if routed through a network. The same applies to camera latency: accurate timing requires that both capture and rendering happen on the same machine, in the same browser context.
Because these tools are entirely client-side, they also work offline. Load the page once and you can run monitor burn-in tests, input lag checks, or webcam latency measurements without an internet connection.
No installation is required. CapyToolkit's hardware tests run entirely in your browser using standard web APIs, with no plugins, no native apps, and nothing to download. For quicker access next time, open any tool page and click the Install App button near the top, which adds CapyToolkit to your Start Menu or home screen so your favorite tools are just a tap away.
No. CapyToolkit doesn't collect or transmit pixel data, input events, or video frames. The tests run entirely on your machine.
Yes. Once loaded, no internet connection is needed. The tools run as local JavaScript with no external calls.
Yes. They use standard browser APIs, so any modern browser on any OS works fine.
Some do. Tools that access your camera or microphone will ask before starting. You can see what each tool needs before granting access.
Most of them do, though display tests are most useful on the screen you are actually evaluating. To test a specific monitor, load the page on the device connected to it.
