Frequently Asked Questions
Everything you need to know about the playground.
Can I test external libraries like Tailwind, FontAwesome, or Axios?
Yes! In the index.html tab, you can add any standard CDN <link> or <script> tag from unpkg, cdnjs, or jsdelivr, and it will immediately execute in the live preview.
How does the Export ZIP button bundle my files?
Live Web Tester utilizes JSZip directly in your browser to bundle your index.html, style.css, and script.js files into a standard compressed .zip archive and triggers an immediate local download without uploading your code anywhere.
Is Live Web Tester really 100% free forever?
Yes. Because our application runs completely client-side in your browser, our hosting costs on edge CDNs are minimal. We do not require accounts, credit cards, or premium subscriptions.
