Centrifugo PRO overview
Centrifugo PRO is an extended version of Centrifugo with a set of additional features. These features can provide your business with unique benefits – granular channel permission control, lower CPU utilization on Centrifugo nodes, backend protection from misusing, next level system observability, and more.
Features
Centrifugo PRO includes the following features:
- Everything from Centrifugo OSS
- Channel and user tracing provides a way to look at all client protocol frames in the specified channel or per user ID.
- Real-time analytics with ClickHouse for a great system observability, reporting and trending.
- Channel capabilities for controlling channel permissions per connection or per subscription.
- User status feature to understand activity state for a list of users.
- Operation throttling to protect client API from misusing and frontend bugs.
- Connections API to filter and inspect active connections.
- User blocking API to block/unblock abusive users by ID.
- JWT revoking and invalidation to revoke tokens by token ID (JTI) and invalidate user's tokens on issue time basis.
- Faster performance to reduce resource usage on server side.
- Optimized Redis Engine to reduce CPU and Redis Cluster sharded PUB/SUB support.
- Singleflight for online presence and history to reduce load on the broker.
- Near real-time CPU and RSS memory usage stats.
PRO features can change with time. We reserve a right to move features from PRO to OSS version if there is a clear signal that this is required to do for the Centrifugo ecosystem.
Sandbox mode
You can try out Centrifugo PRO for free. When you start Centrifugo PRO without license key then it's running in a sandbox mode. Sandbox mode limits the usage of Centrifigo PRO in several ways. For example:
- Centrifugo handles up to 20 concurrent connections
- up to 2 server nodes supported
- up to 20 API requests per second allowed
This mode should be enough for development and trying out PRO features, but must not be used in production environment as we can introduce additional limitations in the future.
Centrifugo PRO is distributed under commercial license which is different from OSS version. By downloading Centrifugo PRO you automatically accept license terms.
Pricing
To run without limits Centrifugo PRO requires a license key.
