Responsive Iframe Mobile Previewer with Proxy Support
Struggling with X-Frame-Options or broken iframe previews? ViewCore combines direct iframe rendering with an intelligent server proxy to display any site seamlessly.
How ViewCore Handles X-Frame-Options & CORS Blockers
Many websites send X-Frame-Options: SAMEORIGIN or restrictive Content Security Policies to block standard iframe embeds. ViewCore automatically detects frame-busting security headers and offers a 1-click Live Proxy Mode that strips restrictive headers, upgrades HTTP to HTTPS, and streams the site live into your mobile frame canvas.
Features for Web Developers
- Dynamic Hardware Framing: Choose between Notch, Hole Punch, or Dynamic Island cutouts.
- Live Proxy Toggle: Switch between direct iframe and proxy mode instantly.
- Exact Device Dimensions: Renders at exact 393px × 852px iPhone 15 Pro resolution.
