Apache Unomi 3
A major CDP release
Platform foundation in 3.0, product leap in 3.1. At the heart of that leap: a platform-wide multi-tenancy refactor — plus OpenSearch, cluster tasks, API stability, and a leap in quality.
- Multi-tenancy — isolate profiles, events, segments, rules & schemas per tenant
- 119/119 documented 2.x OpenAPI paths retained
- Tests grew faster than production code (~5.3× vs ~1.7× LOC)
Multi-tenancy
A platform rebuilt for tenants
Multi-tenancy in Unomi 3.1 is not a thin wrapper — it was a major refactoring of the platform: tenant-aware persistence, public and private API keys, isolation of profiles, events, segments, rules, and schemas, plus usage and retention APIs for control planes.
- Public & private API keys per tenant
- Data plane isolation across the CDP
- Built for SaaS and multi-customer deployments
AI agents
Also: customer memory for the agentic stack
Unomi is not an LLM. It is the open-source CDP agents query and update — retrieve context, store observations, summarize profiles, and build segments, with consent built in.
Why a Customer Data Platform?
Unify your customer data.
Personalize every experience.
Organizations collect data from many channels and systems — web, mobile, email, in-store, CRM, support desks, IoT devices, and more. A CDP brings it all together into a single customer view, enabling smarter decisions, better experiences, and seamless service across every touchpoint.
Unified Profiles
Consolidate customer data from every touchpoint into rich, persistent profiles.
Segmentation & Scoring
Build dynamic audience segments and lead scoring rules in real time.
Privacy Built In
GDPR consent management, data portability, and privacy controls as first-class features.
Extensible
Plugin architecture with REST API, Groovy actions, and connectors to integrate anything.
AI-ready data
Privacy-first context for AI systems
Feed agents and models with unified profiles and events — and write durable customer memory back into the CDP. Open, consent-aware, model-vendor-neutral.
