Secure iframe rendering

Safe Content Frame

Render untrusted HTML content securely in sandboxed iframes with unique origins per render.

HTML Input

Ready to render

Sandboxed Output

How it works:

  • Each render gets a unique origin derived from a hash
  • Content runs in a sandboxed iframe with allow-scripts
  • Cross-origin isolation prevents access to parent window
  • No cookies, localStorage, or other storage from the parent domain
