You could do the following:

  1. Create (or find) a service that renders URLs as preview images
  2. Load that image on mouse over and show it
  3. If you are obsessive about being live, then use a Timer plug-in for jQuery to reload the image after some time

Of course this isn't actually live.

What would be more sensible is that you could generate preview images for certain URLs e.g. every day or every week and use them. I image that you don't want to do this manually and you don't want to show the users of your service a preview that looks completely different than what the site currently looks like.

HTML structure

<div id="app">
<div class="box">
    <div class="title">How to preview link with iframe and javascript?</div>
    <div class="note"><small>Note: Click to every link on content below to preview</small></div>
    <div id="content">
        We'll first attach all the events to all the links for which we want to <a href="https://htmlcssdownload.com/">preview</a> with the addEventListener method. In this method we will create elements including the floating frame containing the preview pane, the preview pane off button, the iframe button to load the preview content.
    </div>
    <h3>Preview the link</h3>
    <div id="result"></div>
</div>

We'll first attach all the events to all the links for which we want to preview with the addEventListener method. In this method we will create elements including the floating frame containing the preview pane, the preview pane off button, the iframe button to load the preview content.

<script type="text/javascript">
(()=>{
    let content = document.getElementById('content');
    let links = content.getElementsByTagName('a');
    for (let index = 0; index < links.length; index++) {
        const element = links[index];
        element.addEventListener('click',(e)=>{
            e.preventDefault();
            openDemoLink(e.target.href);
        })
    }

    function openDemoLink(link){

        let div = document.createElement('div');
        div.classList.add('preview_frame');
        
        let frame = document.createElement('iframe');
        frame.src = link;
        
        let close = document.createElement('a');
        close.classList.add('close-btn');
        close.innerHTML = "Click here to close the example";
        close.addEventListener('click', function(e){
            div.remove();
        })
        
        div.appendChild(frame);
        div.appendChild(close);
        
        document.getElementById('result').appendChild(div);
    }
})()
