Why thousands of users choose TechTester over other sites
No signup. No account. No nonsense.
Every tool on TechTester works the moment you open the page. There are no registration walls, no email forms, and no free trial countdowns. Most competitor sites require an account just to access basic features. We don’t believe in that. You came here to get something done so let’s get it done.
Zero ads cluttering your experience
Major keyboard and gamepad testing sites like IObit and keyboardtester.uk rely heavily on Google AdSense banners that slow down the page and distract you mid test. TechTester is built differently. Our tools load fast and stay out of your way, so you can focus on the task at hand.
The only hub with Arabic keyboard support
If you type in Arabic, you know how hard it is to find a tool that properly handles RTL layouts and Arabic character keys. TechTester’s Arabic keyboard checker is purpose built for Arabic speaking users across the Middle East, Pakistan, North Africa, and beyond making us the only all in one tech tool site with genuine Arabic keyboard testing.
Works with every major controller brand
gamepadtester.com and hardwaretester.com support generic controllers but provide minimal guidance for specific consoles. TechTester’s gamepad checker includes dedicated support and step by step instructions for PS5 DualSense, Xbox Series X/S, and Nintendo Switch Pro Controllers so you always know exactly what you’re testing and what the results mean.
Your data stays private — always
All TechTester tools run entirely in your browser. Keystrokes from the keyboard checker are never recorded or transmitted. Payslip data is never sent to our servers. Controller inputs are processed locally. We take privacy seriously because what you type and what you earn is your business, not ours.
Fast enough for mobile
Unlike legacy tool sites built only for desktop, TechTester is fully optimised for mobile browsers. Whether you’re on a smartphone, tablet, or laptop, every tool loads quickly and performs as expected. No separate app required.

TechTester vs other online tool sites
Most online tool websites are built around a single purpose a keyboard tester here, a payslip maker there. That means you’re constantly jumping between tabs and trusting different sites with your data. TechTester was built to end that. We combined the most needed tools into one fast, private, and completely free destination.
Other keyboard checker sites like keyboardtester.com offer a solid basic test but rely on advertising revenue and lack any support for non English keyboard layouts. Arabic speakers, in particular, have had almost no dedicated testing option until now. TechTester’s Arabic keyboard checker fills that gap with purpose built RTL support.
For gamepad testing, tools like gamepadtester.com and hardwaretester.com handle most controllers but provide minimal console specific guidance. If your PS5 DualSense or Nintendo Switch Pro Controller is showing unusual behaviour, you need context not just a blinking button map. TechTester gives you that context.
And when it comes to payslip generation, enterprise tools like Zoho require you to sign up, log in, and hand over your email address before you can create a single document. TechTester’s payslip generator skips all of that. Open the page, fill in the details, and download your PDF. Done.
