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.

Ratings and Reviews
It is good program and save lots of time to configure different env. And provide quick way to run program. There are some bugs. And some useful features are not available. I emailed the owner, but never get reply. For most of the software I purchased, I could get a prompt from the owner, but not this one. So I think maybe this is not actively maintained.
Fantastic lightweight editor+runner
Developers will always scoff at apps like these (especially ones whose primary notability derives from the Mac App Store—normally a bit sketchy), which make you pay for what you could likely get for free from such popular editors as Sublime, Atom, Notepad++, Vim, etc. But I can whole-heartedly vouch for the legitimacy of Coderunner on all fronts. It is virtually bug-free, has a dead-simple interface, is extremely fast, is delightfully customizable, has excellent syntax highlighting for a good variety of languages, and most importantly, lets you run your programs with the touch of a button, no strings attached.
I personally use it for small programs and self-contained bits of code—it serves as an excellent, speedy testing groundy to dump snippets into or to build up sections of a larger project. It is also a fine editor for HTML and Markdown, as it renders it in the output window when you press run. Of course, I’ll tend toward full IDE’s for larger, more interconnected projects, but when it comes to single-file programs, I find it faster and more pleasant than the more popular editors.
I rarely write reviews, but definitely my favorite IDE for writing quick scipts by far. I bought in at coderunner 1, and that fact that every update has been free to me is wonderful. A very simple UI and the amount of languages it supports is surprising. The compiler and debugger in the application are painless. Granted, this is not an application for full scale projects. But, you wouldn't use a steak knife to cut down a tree would you? Keep it up, this is an essential for mac developers.
With Family Sharing set up, up to six family members can use this app.
