About CPS Testers

What This Site Is

cpstesters.com/ is a focused collection of input-testing tools — click speed, keyboard diagnostics, mouse polling and accuracy, aim training, typing speed, and screen checks — built to answer a specific, practical question: how fast, accurate, and reliable is your hardware and your own reflexes, right now, measured precisely.

Every test runs directly in the browser using JavaScript's high-resolution timing APIs rather than the coarser timers many click-test sites still rely on. There's nothing to install and nothing to sign up for — you land on a tool page, the test is ready immediately, and your result is yours to keep or discard.

What's on the Site

The tools fall into a few practical categories:

New tools generally get added when there's a real gap — a specific test or generator that Minecraft, keyboard, or competitive-gaming communities keep asking for and that existing sites do poorly or not at all, not simply to pad out a tool count.

How the Site Is Run

• Always free. Every tool here is free, with no premium tier or paywalled features. The site is supported by standard display advertising, not by charging for tools.
• No accounts, no server-side storage. There's nothing to sign up for. Where a tool keeps a history (like recent test scores), that data lives in your browser's local storage on your device — it's never sent to a server, and clearing your browser data removes it.
• Built and maintained independently. This isn't a large company product — it's built, tested, and kept up to date by one person handling both the tools themselves and the content around them. That means changes ship fast, but also means the site is one project among several, not a 24/7 support desk.
• Timing accuracy is the priority. The click and reaction tests specifically use performance.now() for sub-millisecond timestamp precision rather than the less accurate setInterval approach, because a "speed test" tool is only useful if the number it reports is actually trustworthy.

Why This Site Exists

cpstesters.com/ started as a single click-speed counter, built to answer one narrow question fast and accurately. It grew into a broader toolset over time because the same underlying need kept showing up in different forms — someone wanting to check their mouse's real polling rate, verify their keyboard registers every keystroke, benchmark their typing speed, or check a new monitor for dead pixels before a return window closes.

Each tool exists because that specific problem came up, not because of a plan to "cover every category." That's also why some tools are more built-out than others — the ones that get used most (the core CPS test, the Minecraft click tests, the mouse and keyboard checkers) get the most ongoing attention.

If you use these tools regularly, you're using the same platform a solo developer actively maintains and improves based on what people actually ask for — which is also why the contact form below goes straight to a real inbox, not a support ticket queue.
