Embed Anything

Modern browsers and SaaS platforms increasingly use security headers like X-Frame-Options: DENY and aggressive Content Security Policies (CSPs) to prevent embedding.

For teams building portals or dashboards that rely on integrating third-party tools-this is a dealbreaker.‍

Webfuse enables safe, seamless embedding of third-party apps by rewriting headers and policies in real-time-no vendor cooperation needed.

Embedding Blocked by X-Frame-Options or CSP

• You try to embed an external dashboard-and get a blank screen
• The browser blocks the iframe due to CSP or X-Frame-Options headers
• You contact the vendor-and they say no
• You’re left maintaining fragile proxy servers or abandoning the integration

How Webfuse solves this

Dynamic Header Rewriting Inside a Virtual Web Session
Webfuse works like a real-time proxy layer. It fetches and rewrites every response-including CSP headers, iframe restrictions, and domain enforcement.

Here’s how it works:

1. Create a SPACE and set the START PAGE to the target URL
2. Configure a custom domain (e.g., portal.yourdomain.com)
3. Embed the SPACE link into your app as an iframe
4. Webfuse rewrites headers, hosts it under your domain, and isolates the session

Key Benefits

• Bypass Embedding Restrictions: Safely ignore X-Frame-Options and restrictive CSP rules
• No Backend Changes Required: Works without modifying the third-party app
• Custom Domain Mapping: Makes the app appear first-party, enabling iframe support
• Secure & Auditable: All sessions are sandboxed, logged, and access-controlled
• Composable Sessions: Add overlays, AI assistants, chat, or analytics via Webfuse Extensions

‍Examples

• Embed Google Analytics dashboards into client portals
• Display LMS or training platforms inside compliance portals
• Integrate third-party tools into internal ERP/CRM interfaces
• Preview documents and reports from external services in-app
