Keen — Real-time event streaming and analytics

Keen is an event streaming and analytics platform for developers and product teams building data-driven applications

Keen is a fully managed event streaming and analytics platform designed to collect, analyze, and visualize data in real-time. It provides business owners and product teams with a ready-made infrastructure to embed customer-facing metrics and internal dashboards into their applications. By handling the complexities of Apache Kafka and Cassandra, Keen allows companies to track user behavior and operational events without maintaining their own backend database clusters. The platform streamlines the process of capturing event data from multiple sources through a single API. Business leaders use Keen to monitor application performance and user engagement trends as they happen, rather than waiting for nightly batch reports. The service includes a suite of data visualization tools, making it easy to present complex datasets as intuitive charts within your own software product. Integrating this technology reduces the heavy lifting usually required by DevOps teams for data architecture. You can find more details on how this fits into your tech stack at surfai.app. The system handles everything from data ingestion to storage and querying, ensuring that your analytics scale automatically as your user base grows in 2026. Keen operates on a freemium model with a free tier for initial development. Paid plans offer higher event volumes and advanced technical support for growing startups and established enterprises.
