About TechTester - Free Online Tech Tools for Everyone
TechTester is a free online tool website built for everyday users, gamers, HR professionals, and tech enthusiasts around the world. We believe that useful tools should be accessible to everyone without registration, without subscriptions, and without a wall of advertisements getting in the way.

Why we built TechTester
The tools that exist today for keyboard testing, controller diagnostics, and payslip generation are scattered across dozens of separate sites each with their own login requirements, premium plans, and advertising. If you want to test your keyboard you go to one site. If you want to check your PS5 controller you go to another. If you need a payslip you go somewhere else entirely. And most of these sites were never built with Arabic speaking users in mind at all.
TechTester was built to fix that. We put the most needed tools in one place, made them genuinely free to use without any account or download, and built the Arabic keyboard checker from scratch because no good free option existed anywhere.
We are also acutely aware of privacy. Every tool on TechTester processes data entirely in your browser. Your keystrokes, your controller inputs, your salary information none of it ever leaves your device. We do not log it, we do not store it, and we do not sell it.
Our principles
Free means free
Every tool on TechTester is free without conditions. There is no free tier with a paid upgrade, no watermarked output that requires payment to remove, and no feature locked behind registration. When we say free, we mean it.
No account required
Requiring an account to use a basic tool is a choice that benefits the site owner, not the user. Accounts mean email addresses, which means marketing lists. TechTester will never ask you to create an account to use any tool.
Privacy by design
All TechTester tools are built so that your data never leaves your browser. This is not a privacy policy promise it is an architectural decision. There is no server side processing to worry about because there is no server side processing.
Built for everyone
TechTester serves users across the world including Arabic-speaking users who have been underserved by English language tool sites for too long. We are committed to expanding language support and building tools that are useful across cultures and geographies.
No clutter
Tool sites are notorious for surrounding their tools with layers of advertising, popups, newsletter prompts, and related product upsells. TechTester is designed around the tool clean, focused, and fast to load.
The story behind TechTester
TechTester started with a simple frustration the experience of searching for a free keyboard tester online and finding sites that were either full of ads, required signups, or were pushing software downloads. The same frustration applied to controller testing tools and payslip generators. Each category had competitors, but none had combined them into a single clean, trustworthy destination.
The Arabic keyboard checker came from recognising a gap that had existed for years. Arabic speakers make up hundreds of millions of internet users worldwide, yet dedicated Arabic language keyboard testing tools were virtually non-existent in English-language web tools. TechTester’s Arabic keyboard checker was built to fill that gap with proper RTL support and Arabic Unicode handling.
We continue to build new tools based on what users actually need. If there is a tool you would like to see on TechTester, use the contact form and tell us every suggestion is read and considered.
