About KeyTesterOnline.com
A free, browser-based keyboard testing tool and editorial hub for everyone who types, games, or builds keyboards.
What We Do
KeyTesterOnline.com gives you a fast, accurate way to check every key on any keyboard — desktop, laptop, mechanical, membrane, or low-profile — with no downloads, no accounts, and no tracking of what you type. The visualizer runs entirely in your browser: press a key, watch it light up, and confirm the switch is registering.
Beyond the tool, we publish practical guides on keyboard technology: how to diagnose dead keys and stuck switches, what N-key rollover (NKRO) really means and how to test for it, how to identify and fix ghosting, what to do when a key starts chattering (double-typing), liquid-spill rescue, and when a keyboard is worth repairing vs. replacing.
Who Operates This Site

Liquid Amber Partners LLC is an independent operator of a small portfolio of consumer tool sites. We have no relationship with any keyboard manufacturer or switch brand, and we don't accept payment for article placements or editorial direction.
Editorial Approach
Every article on this site is written to help real users make real decisions about their keyboards. We test recommendations against our own tool where relevant (for example, verifying NKRO or reproducing a chatter symptom), link to primary sources such as manufacturer support pages, and update articles when warranty or return policies change.
Articles may link to products on Amazon and other retailers through affiliate programs (see our Privacy Policy and Terms of Service). Affiliate revenue helps keep the keyboard testing tool free for everyone. Product recommendations are selected on the basis of technical relevance to the article topic — switch type, build quality, NKRO support, layout — not the size of the commission.
How the Site Is Funded
KeyTesterOnline.com is funded through two sources: (1) display advertising served by Google AdSense, and (2) affiliate commissions from Amazon Associates and similar programs. We do not sell your personal information. See our Privacy Policy for detail on advertising cookies and opt-out options.
