Our Story
ABC Tester was born from a simple frustration that many gamers share: finding reliable, free tools to test gaming peripherals was unnecessarily difficult. Most existing tools were either outdated with clunky interfaces, required downloading suspicious software, or hid essential features behind expensive paywalls.
We knew there had to be a better way. In 2023, we set out to create a comprehensive testing platform that would be modern, accurate, and completely free. Starting with just a handful of basic tests, we've grown to offer over 90 professional-grade tools covering everything from mouse performance to cognitive training.
Today, ABC Tester serves millions of users worldwide. From bedroom streamers testing their new mouse to esports organizations evaluating equipment, our tools have become a trusted resource in the gaming community. We're proud to have helped countless players optimize their setups and improve their gaming performance.
But we're just getting started. Our team continues to develop new tools, improve existing ones, and listen to community feedback. Every suggestion from our users helps shape the future of ABC Tester.
Meet the Creator
Tabassum Khan
Founder & Lead Developer
With over 7 years of hands-on web development experience, I've always been passionate about writing clean, performant code and competitive gaming. ABC Tester was born out of a simple need: I wanted a unified, reliable platform to test my gaming peripherals, aim, and cognitive skills without clunky interfaces or paywalls.
As a full-stack developer who loves building free, open-access tools, I poured my expertise in JavaScript, responsive design, and browser APIs into creating the ultimate testing suite. Whether it's measuring raw click speed, diagnosing mouse polling rates, or training visual memory, every tool has been crafted with precision and user experience in mind.
When I'm not coding or gaming, I'm constantly researching new ways to help players optimize their hardware and improve their in-game performance. ABC Tester is and always will be 100% free — because every gamer deserves the right tools to reach their full potential.
