What is Finders Keypress?

Finders Keypress is a free, browser-based keyboard tester. It captures every keypress and scroll event and visualizes key codes, modifiers, inter-key latency and rollover with live charts. It runs entirely in your browser with no install and no tracking.

Can I test a scroll wheel or volume control?

Yes. Rotating a scroll wheel or volume control fires wheel events, which Finders Keypress captures with direction and cumulative rotation charts. On touch devices you can also drag the on-screen scroll wheel.

Is Finders Keypress free and private?

Yes. It is completely free and 100% local: no data ever leaves your browser, there are no cookies, no analytics and no tracking. Captured events live only in memory until you clear or refresh.

Does it work on mobile phones?

Yes. If you connect a Bluetooth or USB keyboard to your phone, real key events are captured. With no keyboard attached, use the built-in on-screen virtual keyboard and scroll wheel to test touch input.

What it measures

Key code & key value: the exact event.code and event.key.

Latency: milliseconds between keydowns, charted over time.
Rollover (NKRO): hold many keys to confirm they all register.
Scroll: direction and cumulative travel.

Frequently asked questions

Is Finders Keypress free?

Yes, completely free, with no account, no ads and no upsell.

Which keyboards does it work with?

Any standard USB or Bluetooth keyboard: mechanical, optical, magnetic or membrane. The browser receives standard key events, so every key is tested the same way. It's ideal for checking a new board, verifying remaps, or confirming every key registers.

Can I test every key, including media keys and the scroll wheel?

Yes. Every keydown and keyup is logged with its key code and modifiers, and a scroll wheel or volume control is captured with direction and a cumulative-rotation chart. On a phone, drag the on-screen scroll wheel.

Is my data private?

Completely. Everything runs locally in your browser, with no cookies, no analytics, no network calls. Captured events stay in memory until you clear or refresh.

Does it work on mobile?

Yes. Connect a Bluetooth or USB keyboard to capture real events, or use the built-in virtual keyboard and scroll wheel to test by touch.
