SharedWorker Multiplex

A textbook-grade real-time multiplexer for cross-iframe and cross-tab communication.

Parent Main Client Connected

The parent window registers directly with the SharedWorker background thread as a primary peer node.

Hub SharedWorker
SharedWorker Wire Trace
[--:--:--] [Trace] Listening for SharedWorker payload broadcasts...
Embedded Client Sandboxes (Iframes) Iframe Mode

These two iframe nodes share the same browser window context and coordinate entirely via the central SharedWorker background thread.

Multi-Tab & Cross-Window Playground

SharedWorker coordinates communication across **any open browser tab or window** running on the exact same origin. Copy the server URL below, open it in another tab or side-by-side window, and watch the system topology map dynamically grow to show your new session in real-time.
