Diagnose Hardware with Keyboard Test
A sticky spacebar or a dead 'Enter' key can ruin your productivity and your gaming session. The **Keyboard Test** tool at **Online Tool Base** provides an instant, visual way to check the health of your keyboard. It lights up an on-screen virtual keyboard in real-time as you press distinct keys on your physical device.
This tool is essential for gamers checking for "ghosting" (the inability to register multiple simultaneous keypresses), typists verifying a used keyboard purchase, or anyone spilling coffee on their laptop. **onlinetoolbase.online** captures the raw key events from your browser, allowing you to confirm that the signal is reaching the computer, even if the letter isn't appearing in your text editor.
Why Use This Tool?
Hardware diagnostics often require installing shady software. Our tool runs safely in your browser. Use it to map out unknown keycodes, test N-Key Rollover (NKRO) capabilities, or simply verify that your new mechanical keyboard switches are all actuating correctly. It supports standard standard ANSI and ISO layouts, covering most keyboards used globally.
Key Features
- Real-Time Visualization: Keys light up green the moment they are pressed.
- Ghosting Detection: Hold down as many keys as possible to see the limit.
- History Log: Shows the sequence of key presses for debugging input lag.
- Universal Support: Works with USB, Bluetooth, and Laptop keyboards.
How to Use
- Open the tool and ensure the window is focused.
- Start typing on your physical keyboard.
- Watch the on-screen layout respond to your inputs.
- Review any keys that remain gray (unregistered) to identify faults.
Technical & Privacy Note
Your keystrokes are safe. The **Keyboard Test** from **Online Tool Base** processes input events locally within the active browser tab. We do not record your passwords, key history, or store any input data. The visualization resets the moment you refresh the page.
