Runno

关于

Runno is a powerful collection of JavaScript packages designed to execute code in multiple languages and WASI binaries within a secure sandbox. Leveraging WebAssembly and WASI, it creates a virtualized Unix-like environment with a fake file system and no network access, perfect for browser-based code execution, server-side sandboxing, or integration as an MCP server. This allows for seamless, isolated code testing and execution without complex local setups, promoting accessibility and efficiency for developers and educators alike.

主要功能

• Web Components for browser-based code execution with an integrated editor and controls.
• Secure sandboxing for diverse programming languages, including Python, Ruby, JavaScript (QuickJS), C/C++, PHP, and SQLite.
• Direct execution and management of WebAssembly WASI binaries.
• Emulates a Unix-like environment with a virtual file system and terminal output.
• Supports multiple execution contexts: browser, Node.js, and server-side JavaScript runtimes, including an MCP server implementation.
• 753 GitHub stars

使用案例

• Facilitating programming education by making interactive code examples runnable directly in the browser without local installations.
• Providing a secure, isolated environment for testing and verifying small code snippets and examples.
• Integrating as an MCP (Multi-Cloud Platform) server for remote sandboxed code execution in various environments.
