About Keen
What is Keen?
Keen is a fully managed event streaming platform that lets developers collect, store, and analyze real-time event data without building or maintaining streaming infrastructure. It provides a REST API for ingesting data, persistent storage with AES encryption, a Compute API for real-time queries, and a Data Viz Library for embedded dashboards.
Who is it for?
Keen is built for developers and product teams at SaaS companies (like Travis CI, Polycom, Pixlee) who need to add event-driven features, custom analytics, or in-app dashboards to their applications. It is not designed for casual users or small side projects with very low event volumes — those may find the Team plan's 250K events too limited.
What problem does it solve?
Building and maintaining streaming infrastructure (Apache Kafka, Storm, Cassandra) takes months and expensive DevOps resources. Keen eliminates that overhead with a multi-tenant, fully managed architecture so teams can stream, query, and visualize event data in minutes. Use cases include detecting memory leaks, tracking user behavior, and delivering real-time product analytics.
