Typometer

Typometer is a tool to measure and analyze the visual latency of text editors.

Editor latency is the delay between an input event and a corresponding screen update — in particular, the delay between keystroke and character appearance. While there are many kinds of delays (caret movement, line editing, etc.), typing latency is a major predictor of editor usability.

Check the article typing with pleasure to learn more about editor latency and its effects on typing performance.

> While there are many excellent terminal emulators available, they all force you to choose between speed, features, or native UIs. Ghostty provides all three. In all categories, I am not trying to claim that Ghostty is the best (i.e. the fastest, most feature-rich, or most native). But Ghostty is competitive in all three categories and Ghostty doesn't make you choose between them.

Ghostty doesn’t claim to be the fastest.

Being at the bottom is not what I call competitive.

It’s above kitty? From the numbers posted earlier
