# What is supported and limits

## Supported

- Public, private, presence and encrypted channels
- Client events on private and presence channels, up to 10 a second per connection
- User sign-in, and events sent to a user
- The HTTP API: an event to up to 100 channels at once, batches of up to 10 events, channels and their users, and closing the connections of a user
- Events of up to 10 KB

Not yet: webhooks, and replaying the last event of a cache channel, so a cache channel always reports a miss. WebSocket connections only, with no HTTP fallback.

## Limits

Connections are unlimited on your subscription WordPress sites, under fair use. A site keys stop working when its subscription ends, and its secret can be rotated at any time from its keys in your account.
