Runno helps you make embeddable code snippets that run in the browser with WASM. It supports snippets in Python, JS, C/C++ and more. Plus with the Runno NPM package you can run and test arbitrary code in your blog, tutorials or resources.

Hey everyone! A year or so ago I was playing around with building an online Introduction to Python course, but I got distracted by this problem that seemed like it should be solved: how can I embed runnable snippets on the web? There’s a bunch of closed-source solutions that rely on other services. I was hoping for a way to just install a package, and then run code. Especially small snippets like print, input and if statements. So I started building Runno. It lets you embed snippets of code from a few different languages (Python, JavaScript, C, C++ and SQL currently) within your website and runs it all client side using Web Assembly. You can use it without any packages using an iframe, or install the npm package and use it as a Web Component. Happy to answer any questions you have about it!

I can see the use case for blogging and online teaching, especially the "coding for kids" idea I have had for a while

I appreciated the project. With runno NPM, you can actually run and test custom code in your blog, tutorials, or resources.
