Why some websites don't work in iframes

Many websites prevent embedding in iframes for security reasons:

  • X-Frame-Options headers block embedding to prevent clickjacking attacks
  • Content Security Policy (CSP) with frame-ancestors restricts which sites can embed content
  • JavaScript can detect and block iframe embedding

Sites that typically provide embeddable content:

  • YouTube, Vimeo, and other video platforms (via their embed URLs)
  • Google Maps, OpenStreetMap
  • Social media embed widgets (Twitter, Instagram)
  • Code playgrounds (CodePen, JSFiddle)

For your own websites, you can control iframe embedding with headers:

X-Frame-Options: ALLOW-FROM https://your-trusted-site.com
