So in my bidding SaaS service, it's a website template provider, right? You can edit your templates, but the thing is, it doesn't have a preview that you can quickly see the changes you made. How do I get a preview of another site on another site, like I'm in my admin page, and how do I render the actual site on there? So whenever I make a change, it will like automatically refresh itself so the user can see the change.
