About JanetEngelhard

JanetEngelhard is a collection of free, browser-based diagnostic tools for gamers, streamers, and anyone who wants to quickly check their hardware without installing software.

What We Build

Every tool on this site runs directly in your browser using standard web technologies, primarily the Gamepad API for controllers and joysticks, along with native mouse and keyboard events for click-speed testing. There's nothing to download and nothing to install. Connect your device, press a button, and see results instantly.

Our Approach

We built this site around real, working tools rather than static pages. Each tool is designed to genuinely read live input from your hardware, not simulate results. Where a browser's capabilities are limited (for example, true HID polling-rate measurement or gyroscope data), we say so plainly rather than making claims the tool can't back up.

Privacy First

None of your inputs, click data, or controller readings are ever transmitted to a server. Everything happens locally in your browser and disappears when you close or refresh the page. See ourPrivacy Policy for full details.
