Monkeytype

Monkeytype provides you with a minimalistic typing test, featuring many test modes, an account system to save your typing speed history and user configurable features like themes, a smooth caret and more. The free and open-source tool features leader boards and a community that thrives on the idea of typing fast. By default, the tool uses the most common 200 words in the english language to generate its tests. However, it allow you to configure the settings to challenge you further, and improve in areas where your typing lacks.
