Run Code in Any Language

CodeRunner was built on the principle that you should be able to run your code instantly in any language. CodeRunner can run code in 23 languages out-of-the-box, and can be easily extended to run code in any other language. Adding a language is as easy as entering its terminal command.

CodeRunner can also run multi-file projects without any manual setup required.

Code Completion

Advanced Code Completion

Any programmer knows the importance of good code completion. That's why CodeRunner supports full-blown IDE-level code completion for most languages, that includes fuzzy-search, tab-selectable placeholders, and documentation snippets.

Code Templates

Quickly get down to coding without the need to write main functions or other repetitive code.

CodeRunner includes a number of fully-customizable templates for each language, to easily create classes, scripts, main methods, and the like. This also makes it easy to create multi-file projects.
