Hi, I'm Nasir, founder and dev of KeyboardTester.click.

A few years back, while working, I got stuck with a keyboard switch issue. I went online to figure out what happened and couldn’t find one complete browser-based keyboard diagnostic tool, so I built one for myself.

Then I built another tool, then another, and now the site has 90+ tools and is still growing.

You can check the full list here: https://keyboardtester.click/pages/all-tools.php

The project is open source under the MIT license. I’m also running out of ideas, so I’d love suggestions from other builders: what keyboard, browser, gaming, or hardware test tool should I build next?
