# Runno

> Use this tool when you need to execute code securely in a sandboxed environment, isolated from system resources and networks. Runno solves the problem of safe code execution, particularly in educational settings and browser/Node.js environments, by utilizing WebAssembly and WASI to run code in complete isolation. It takes in code inputs and outputs results, providing a secure interface for executing code without risking system compromise.
