Frequently Asked Questions
Quick answers to common questions about code execution, privacy, ZIP export, and external libraries.
Is my code saved or shared with anyone?
No. Live Web Tester runs 100% in your local browser session. We do not store, index, or transmit your source code to any external servers or third parties.
Can I import external CSS libraries like Tailwind or Bootstrap?
Yes! In the index.html tab, you can add any <script src="..."> or <link rel="stylesheet" href="..."> from popular CDNs like cdnjs, unpkg, or jsdelivr.
How does the ZIP export work?
When you click the "Export ZIP" button, the JSZip client-side library compiles your HTML, CSS, and JS tabs into a clean directory archive and triggers a native browser download without sending data to a server.
Why does the editor work completely offline?
Because there are no backend APIs or database calls required to evaluate your code. Everything is rendered directly in a local sandboxed browser iframe.
