Pusher Rate Limits
Pusher Channels gates per-app concurrent connections and daily message volume by plan tier (100 connections / 200K msg/day on Sandbox up to 30K / 90M on Growth Plus). Server-side HTTP publish endpoints additionally enforce a per-channel-per-second message cap. Beams enforces per-publish payload size and per-instance throughput caps. HTTP 429 is returned when caps are exceeded.
