What Is a Keyboard Heatmap?
A keyboard heatmap tracks which keys you press and how often, then visualizes the frequency data as a color gradient overlaid on a keyboard layout. Keys you press frequently glow warm colors like red and orange, while rarely-used keys stay cool blue or neutral. This tool runs entirely in your browser and counts physical key presses in real time as you type naturally. It does not record the text you write or the order of keystrokes — only the per-key count. The resulting heatmap reveals your typing patterns, your most-relied-upon shortcuts, and which keys see the heaviest wear. You can export the final heatmap as a PNG image for sharing or reference.
How to Use the Keyboard Heatmap
Click the Start Tracking button, then type on your physical keyboard as you normally would. The on-screen keyboard updates live, with each key gradually changing color as its press count increases. Type for at least a few minutes to build a meaningful pattern — longer sessions produce more accurate heatmaps. When you are satisfied with the data, click Stop to freeze the results. The stats panel shows your total presses, unique keys used, and your single hottest key. Click Export PNG to save the heatmap as an image file. Use the Reset button to clear all data and start a fresh session.
Why Keyboard Usage Patterns Matter
Knowing which keys you use most helps with several practical decisions. Gamers can identify their actual control clusters and optimize keybindings so critical actions sit under the strongest fingers. Programmers can evaluate whether their IDE shortcuts are well-placed or causing unnecessary hand movement. If you are shopping for a mechanical keyboard, a heatmap shows which switch positions deserve your premium switches. Ergonomics researchers use keystroke frequency data to design better keyboard layouts that reduce finger travel distance. Even for everyday typing, spotting that you barely use certain keys can prompt you to learn shortcuts you have been ignoring.
Frequently Asked Questions
Does this log what I typed?
No. TeaFun only counts supported physical keys on this page. It does not upload text or save a transcript.
Why do some keys not light up?
This view tracks the main typing layout shown on screen. Browser shortcuts, media keys, or unsupported layouts may not appear.
What is this useful for?
It helps you spot typing habits, key wear patterns, and control clusters for games, shortcuts, or ergonomics.
