Is the preview secure?

Yes, the code runs inside a sandboxed iframe that blocks access to the parent page (cookies, local storage) for security.

Can I use external libraries?

Yes, you can include CDN links in the HTML tab using standard tags.

Does it save my code?

No, this is a stateless playground. Your code is lost if you refresh (unless you are using a browser extension that saves form data). Always save important work locally.
