About Ryan Marsh
I create free online tools to test mice, gamepads, and other devices.
Hi, I’m Ryan Marsh. I make free browser-based tools to help you check your gear, from mouse polling rates and gamepad inputs to keyboards, displays, and more.

If a tool has helped you, buying me a coffee helps me keep improving it. Thanks for your support!
