FAQ

Is my HTML uploaded to a server?

No — everything runs locally in your browser; your HTML never leaves your device.

Do scripts in my HTML run in the preview?

Yes — inside a sandboxed preview frame that is isolated from the rest of the page and your other files.

Can I use it as a viewer for existing HTML files?

Yes — drop an .html file onto the editor to view it; nothing is uploaded.
