Keen

Keen is a fully managed event streaming and analytics platform built on Apache Kafka, designed to help teams collect, process, and analyze event data without operating their own infrastructure. The service provides hosted Kafka clusters, schema management, and data pipelines that can ingest high-volume event streams from applications, websites, and backend services in real time. Users can define custom event schemas, track user behavior, application performance, or business transactions, and route this data to downstream systems such as data warehouses, BI tools, or custom dashboards.

Keen handles partitioning, replication, scaling, and fault tolerance, allowing teams to focus on data use rather than cluster administration. The platform supports real-time and historical querying, enabling use cases like product analytics, customer journey analysis, anomaly detection, and monitoring of critical business metrics. With SDKs and APIs for common languages and platforms, Keen simplifies integration into existing stacks.
