✨ Welcome to Isolated JS

What is IsolatedJS?​

IsolatedJS is a JavaScript library for the web that allows you to create isolated JavaScript environments. It is a lightweight library that provides a simple API to create and manage isolated JavaScript environments. It is useful for creating sandboxes, running untrusted code, and more. It is heavily based on iframes and the window.postMessage API.

Is it really secure?​

Honestly, I dont know. Its based on sandboxed iframes and the window.postMessage API. It should be secure, but I cannot guarantee it. Use at your own risk. Since really its just a fancy iframe wrapper, as long as iframes are secure, this should be secure too.

Features​

  • Isolated Environment: IsolatedJS creates a separate environment for each instance, which means that the code running in one instance cannot access the code running in another instance.
  • Sandboxing: IsolatedJS provides a way to run untrusted code in a secure environment.
  • Lightweight: IsolatedJS is a lightweight library with no dependencies.
  • Simple API: IsolatedJS provides a simple API to create and manage isolated environments.
