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.

Pusher Rate Limits is the machine-readable rate-limit profile for Pusher on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 9 rate-limit definitions, measuring concurrent_connections and messages_per_day.

Policies

Backoff Strategy
Honor 429 Retry-After and apply exponential backoff with jitter.
Per-channel publish
Avoid publishing more than ~10 events/sec to a single channel; shard across channels.
