Do more with your data

Confluent Cloud provides a complete event streaming platform that helps enterprises transform Kafka into a central nervous system for all events and quickly build real-time, event-driven applications. With fully-managed ksqlDB and Connectors you can easily build stream processing apps using a lightweight SQL syntax and quickly connect Kafka across your critical sources and sinks.

Democratize access to your events

You can write to Kafka in pretty much any language of your choosing, including Java, C, Python, Node.js, Ruby, and more using our client libraries. On top of that, you can ensure backwards and forwards data compatability with Confluent Cloud's Schema Registry.
