Whether you're new to coding or an experienced developer, CodeRunner is the perfect tool to write, run, and debug code quickly in any programming language. Enjoy essential IDE features such as code completion, integrated debugger, and documentation sidebar, all in a lightweight and easy-to-use app designed exclusively for macOS.
Run Your Code Instantly
• CodeRunner was built on the principle that you should be able to run your code instantly, in any language. CodeRunner can run code in 25 languages out-of-the-box, and can easily be extended to support other languages.
IDE-Level 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, including fuzzy-search, tab-selectable placeholders, and documentation snippets.
Debugging with Breakpoints
• A good debugging workflow is key to producing quality code. With CodeRunner, you can set breakpoints and step through your code instantly. Just click the text margin to set a breakpoint and start debugging. Explore the call stack, view and edit variables, and interact with the debugger. Debugging code in any language has never been so quick and easy.
• New in v3.0, the documentation sidebar lets you browse the online docs for your programming language without ever leaving the app. Look up functions, methods, classes, and other symbols instantly by tapping with three fingers on a symbol name, or use the auto-lookup feature. You can even add your own documentation lookup sources.
