Open MQTT: clients connect with NO username or password and subscribe to a public topic for live data (sensors, transit, prices, status). EMQX/HiveMQ allow_anonymous model, but multi-tenant-safe — anonymous reaches only public interfaces, never private topics — and your pipeline runs on the public stream.

The simplest realtime: a PUBLIC WebSocket feed your website visitors subscribe to with NO auth — live scores, status, prices, announcements. Your backend publishes; every open browser gets it instantly. Ably/Pusher public channel, no keys in the browser, no broker to run.
