Frequently Asked Questions

Is HTML Live Preview free?

Yes, completely free. All rendering happens in your browser using an iframe sandbox — no code is ever sent anywhere.

Can I use external libraries like Bootstrap or React?

The sandbox runs in a simple iframe. You can add CDN links in the HTML tab to load external libraries like Bootstrap, Tailwind CSS, or even React via script tags.

Is my code saved?

Your code stays in your browser's memory while the tab is open. Use the Download button to save your work as an HTML file, or the Copy HTML button to copy the complete document.
