The best typing speed test for programmers.

CodeRush allows you to test your writing skills in more than 30 most popular technologies and 3 diffrent game modes.

In addition to calculating your CPM (characters per minute), it provides you with detailed statistics for example the most frequently miss-clicked keys, so that You will pay attention to them in the future.

Example results:

See the this page for a list of proposed features (and known issues) that I will implement (and fix) in the near future.


CodeRush is a one-person project but as long as I will have time, I will make changes to the code myself, so please do not create pull requests unless it is an critical bugfix.

You can still propose new features and report issues like in most open source projects and it will be appreciated.


You can now submit code examples on which our users will test their typing skills. How to do it?

  1. Go to this page (tab "Contribute" on CodeRush website)
  2. Enter your name (nick)
  3. Paste or write code in avaible editor
    • Select a language if you haven't already done it
    • Choose a tab size
  4. Give your code a brief description or name (e.g function name)
  5. Click Send


I made CodeRush open source because without other OS projects I wouldn't be able to get to the point where I am now.

Source code is distributed under the GNU GPL v3 License. However, I would advise against looking here for the best solutions or forking it because this was my first Vue.js project.
