  "what": "The classic hosted pub/sub WebSocket service: your backend triggers events on named channels and browser clients subscribe. Supports private and presence channels with server-side auth endpoints, official SDKs for every major platform, and webhooks for connection and channel events. No infrastructure to run.",
  "why": "Notification badges, live comment counts and 'N people reading this' banners in an afternoon. The API surface is small enough to learn in one sitting, and 200,000 free messages a day covers a lot of ordinary ordinary traffic.",
  "warn": "Billing keys on concurrent connections and messages per day, both of which spike exactly when an article goes viral. Exhausting the daily message cap on the free plan stops delivery entirely until the counter resets at midnight UTC.",
