Current use and fit

Widely used for browser clients; WSS is the secure deployment form.

Implementation essentials

  • Define and document the selected subprotocol.
  • Use WSS in production.
  • If carrying Telnet, preserve the normal byte-level option semantics.

Compatibility and safety notes

  • A plain text WebSocket and Telnet-over-WebSocket are not interchangeable.
  • Browser origin and authentication rules still apply.
