Console snippet generator
Open the authorized site page, paste this snippet in DevTools Console, then collect incoming frames from that page context.
Use this only on pages and sockets you are authorized to test. It does not bypass login or permissions; it simply runs from the page you already opened.
Bookmarklet generator
Create a bookmarklet for repeated receive-only debugging on the authorized site page.
Add the generated code as a browser bookmark. Run it while you are on the authorized origin page.
