Paste a URL, get a rich embed, ship it. Then you turn on a strict Content Security Policy and half your embeds stop rendering, thumbnails vanish, or a provider silently fails inside an iframe.</p> <p>I’ve dealt with this a few times, and the tricky part is that “Iframely embed” can mean different things:</p> <ol> <li>A plain iframe hosted by Iframely</li> <li>A script-based embed that injects markup</li> <li>An Iframely result that itself loads third-party content from YouTube, X, Vimeo, Spotify, and friends</li> </ol> <p>That means your CSP has to account for both Iframely and whatever the final provider needs.</p>
