🔍 FAQs: Quick Answers to Your Questions

How does this differ from browser DevTools?
While DevTools require a live site, our tool lets you preview any HTML—even unfinished or local code—without uploading files.

Can I use JavaScript libraries like jQuery?
Yes! Link external scripts via CDN, and see them execute in the live preview.

Is my sensitive code safe?
Absolutely! No code is stored unless you opt for cloud saves (with encryption).

Does it support CSS preprocessors?
While it renders compiled CSS, you can paste SASS/LESS code and see the output.

Can I collaborate in real time?
Yes! Share a project link, and multiple users can edit or comment simultaneously.

💡 Pro Tip: Bookmark this tool to validate third-party embeds (like YouTube or Google Maps) before deploying them to your site!
