Our keyboard tester captures every key press event and displays a visual representation of your keyboard layout. Press any key to see it highlight in orange, confirming that the key is working properly. The tool tracks which keys you've tested and shows real-time statistics about your keyboard's responsiveness.

• Instantly identify stuck, dead, or unresponsive keys
• Test all keys including function keys, modifiers, and special characters
• Visual feedback shows exactly which keys are working
• Perfect for troubleshooting keyboard issues before buying replacement
• Works with mechanical, membrane, and laptop keyboards

This keyboard tester identifies software-detectable key presses. Physical key issues may require professional diagnosis. Some laptop function keys may behave differently depending on system settings.

Our mouse tester tracks all mouse inputs including movement, clicks, and scroll events. Move your mouse over the testing area to see orange trail effects that confirm smooth movement tracking. Click the left and right mouse buttons to verify they're working, and use the scroll wheel to test scrolling functionality with real-time statistics.

• Test all mouse buttons including left, right, and middle clicks
• Verify smooth mouse movement with visual trail effects
• Check scroll wheel functionality in both directions
• Real-time click counting and position tracking
• Compatible with all mouse types including gaming mice

Mouse testing results depend on hardware condition, surface quality, and system performance. This tool provides basic functionality testing and may not detect all potential issues with gaming or precision mice.

Our touchscreen tester detects single and multi-touch gestures on mobile devices and tablets. Touch anywhere on the testing area to see orange circles appear at each touch point. The tool supports up to 10 simultaneous touches and tracks statistics about your touchscreen's responsiveness and multi-touch capabilities.

• Test single-touch responsiveness across entire screen
• Verify multi-touch support with up to 10 simultaneous touches
• Identify dead zones or unresponsive areas on your screen
• Perfect for testing phones, tablets, and touch monitors
• Works on all touch-enabled devices with modern browsers

Touchscreen testing results may vary based on device capabilities, screen protectors, and environmental factors. This tool provides basic touch functionality testing for diagnostic purposes only.

Our reaction time test measures how quickly you respond to visual stimuli. Click the circle to start, wait for it to turn green, then click as fast as possible. The test uses high-precision timestamps to measure your reaction time in milliseconds, providing accurate results comparable to professional testing equipment.

• Accurate millisecond timing for precise measurements
• Track your best time, average, and improvement over multiple tests
• Simple one-click interface suitable for all ages
• Perfect for gamers, athletes, and reaction time training
• No registration required - start testing immediately

Reaction time results can be affected by hardware latency, display refresh rates, and environmental factors. This tool is for entertainment and general assessment purposes, not professional or medical evaluation.

Our typing speed test presents you with a passage of text to type within a time limit. As you type, the tool tracks your words per minute (WPM), accuracy percentage, and typing errors in real-time. Results are calculated using standard typing test methods with 5 characters counting as one word.

• Accurate WPM calculation using industry-standard methods
• Real-time accuracy tracking with error highlighting
• Customizable test duration for different skill levels
• Perfect for job preparation, skill assessment, and improvement tracking
• No registration required - immediate testing available

Typing speed results may vary based on text difficulty, keyboard type, and testing conditions. This tool provides general assessment for improvement tracking and skill evaluation purposes.

Our FPS counter uses the browser's requestAnimationFrame API to measure how many frames your browser can render per second. This gives you insight into your system's performance for web-based games, video playback, and graphics-intensive applications running in your browser.

• Monitor browser rendering performance in real-time
• Track minimum, maximum, and average FPS over time
• Identify performance bottlenecks for web gaming and video
• No software installation - works directly in your browser
• Perfect for optimizing browser settings and hardware upgrades

Browser FPS measurements reflect rendering performance within the web browser only. Results may not represent gaming or application performance outside the browser environment.

Our ping test measures network latency by timing HTTP requests to reliable servers. While not as precise as ICMP ping tools, it provides a good estimate of your connection's response time for web browsing, online gaming, and general internet usage within browser limitations.

• Quick network latency estimation without software installation
• Continuous monitoring mode for extended connection testing
• Track minimum, maximum, and average ping times
• Perfect for diagnosing connection issues and monitoring stability
• Works on all devices with internet connectivity

Browser-based ping testing provides estimates only and may not reflect true network latency. For precise network diagnostics, use dedicated network testing tools and consult with network professionals.
