Broadcast Rate Limiting

Rate limiting helps you throttle client events, backend events, or HTTP REST API calls for read endpoints (like /channels) at the app level.

Choosing a rate limiter driver depends on the architecture the server is deployed in. For local, single-instance servers, the default local driver is sufficient. For multi-node deployments, a Redis server is typically required. If you choose to use Redis to store rate limiting data, please consult our documentation on connecting to Redis.

Environment Variables

NameDefaultPossible valuesDescription



local, redis, cluster

The driver used for rate limiting.



false, true

Only for the redis driver. Whether the client should be initialized for Redis Cluster. You have to specify the DB_REDIS_CLUSTER_NODES value.

  • local - Rate limiting data is stored in-memory and is lost upon server exit.

  • redis - Rate limiting data is centralized in Redis. This driver is recommended when deploying multi-node soketi configurations.

  • cluster - Rate limiting data is centralized within the master instance, that is elected. This driver is recommended when deploying multi-threaded soketi configurations (i.e. PM2)
