code typing test FAQ

What is Codestroke?

Codestroke is an online code typing test designed for developers. You type real code rather than plain prose.

Why measure CPM instead of WPM?

Code contains symbols, brackets, and short tokens, so words per minute can be misleading. CPM measures every typed character.

Which languages can I practice?

You can practice JavaScript, Python, SQL, Java, C++, HTML/CSS, PHP, Go, and Kotlin snippets.

Is Codestroke free?

Yes. The typing test is free in modern web browsers, and you can begin as a guest without creating an account.
