Apache Unomi review
A self-hosted CDP for real-time profiles and personalization, with a focused integration footprint.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Apache Unomi is a self-hosted, Java-based customer data platform for organizations that need to collect and manage customer, lead, and visitor data. It combines persistent and consolidated profiles with real-time event processing, segmentation, scoring, personalization, privacy management, and a built-in web tracker. The platform is distributed as free, open-source software under the Apache License 2.0, making it a fit for teams that want an API-driven personalization foundation they can host and extend themselves.
Its strongest capability is the connection between profile data and real-time decisions. Unomi supports profile conditions, scoring logic, segmentation, and real-time decisioning, allowing organizations to use incoming events and profile attributes for personalized experiences. Built-in privacy management, multi-tenant data isolation, API keys, and an HTTP REST API using JSON add practical controls for deployments serving websites, mobile applications, CMSs, CRMs, and other systems. Groovy actions and Java OSGi plugins provide an extension path when the standard feature set needs to be adapted.
The trade-off is a focused ecosystem. Salesforce is the listed connector, while broader connectivity is handled through the REST API and extensibility options rather than a wide integration catalog. Verified audience activation is also absent, so organizations prioritizing that workflow should consider a platform centered on activation capabilities instead. Apache Unomi is a strong choice for technically capable teams seeking open-source, self-hosted profiles, event processing, and personalization; it is less suitable for buyers that want broad native integrations or a managed activation layer.
