CodeRunner 2

Edit and run code in any programming language with just a single click. With CodeRunner, it has never been easier to write and test code, run scripts, work with algorithms, or simply experiment with a new coding or scripting language.

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 23 languages out-of-the-box, and can be easily extended to run code in any other language.

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, that includes fuzzy-search, tab-selectable placeholders, and documentation snippets.

Debugging with Breakpoints
• New in CodeRunner 2.2, you can set breakpoints and step through code line by line. Just click the text margin to set a breakpoint and start debugging. Explore the call stack, view and edit local variables, and leverage the full power of the debugger by issuing debugger commands. Debugging code in any language has never been this convenient.

Supported Languages for Running Code
• AppleScript, C, C++, C#, Go, HTML/CSS, Java, JavaScript, LaTeX, Lua, Markdown, Node.js, Objective-C/C++, Perl, PHP, Python, Ruby, Rust, Shell Script, Swift, and user-added languages.
