About Syed Ismail & keytester.online
Hi, I’m Syed Ismail – a web developer and MSc Computer Science postgraduate who loves building practical tools that make everyday work a little easier and a lot faster.
Who is behind keytester.online?
I’m Syed Ismail, a developer who enjoys turning ideas into simple, fast, and useful web tools. Over time I’ve explored blogging, SEO utilities, and small automation projects – and keytester.online is one more step in that journey.
With a background in MSc Computer Science, I focus on building tools that are:
- ✔️Lightweight and fast in the browser.
- ✔️Easy to understand even for non-technical users.
- ✔️Focused on a single problem – no distractions.
What does this tool do?
keytester.online lets you test:
- 🎹Windows Keyboard – full layout with numpad, arrows and function keys.
- ⌨️Mac Keyboard – MacBook-style layout with command, option and control keys.
- 🖱️Mouse Buttons – left, right, middle and scroll events with live counters.
- 🖐️Laptop Touchpad – left / middle / right tap zones using the same counters.
Everything runs inside your browser – keystrokes and clicks are used only to highlight keys and update counters. No login, no account, no complicated setup.
Why I built keytester.online
Many people face small but annoying problems: a key stops responding, a mouse double-clicks, or a touchpad feels unreliable. Instead of guessing, you should be able to see what your device is doing in real time.
I built this tool to give:
- 💻Home users a quick way to check if a keyboard or mouse is working before repair or replacement.
- 🛠️Technicians & shops a simple page to use in front of customers while testing devices.
- ⌨️Gamers & typists a way to verify every key, especially WASD, numpad and function keys.
As I continue improving keytester.online, I plan to keep it:
- 🔒Privacy-friendly – no unnecessary data collection.
- ⚡Fast even on basic machines and browsers.
- 📱Responsive – usable on both desktop and mobile screens.
