Runno

Runno is an open source collection of JavaScript packages that allow users and developers to run code in a variety of programming languages directly in a browser or Node environment, using a secure WASI-powered sandbox. It offers tools such as web components for embedding runnable code examples, sandboxed code execution for multiple runtimes, and a Model Context Protocol (MCP) server. This makes it ideal for programming educators, documentation authors, and developers seeking a secure, easy way to embed live code execution in web applications or learning platforms.
