Blog
Welcome to the Apache Unomi Blog
Longer-form writing for Unomi 4, AI/CDP builders, and the community.
Apache Unomi has long shared news through the homepage, events & talks, mailing lists, and release announcements. With Unomi 4 — a major CDP release with a modern runtime, multi-tenancy, OpenSearch, and a stronger role as customer memory for AI agents — we want a home for longer-form writing.
This Blog is that home.
What you will find here
- Unomi 4 — what changed since 2.x, and what it means for operators and builders
- AI & CDP — using Unomi as privacy-first context for agents and personalization
- Upgrades & API stability — including REST compatibility mode for Unomi 2.x and 3.x clients
- Community — contributors, meetings, and how to get involved
Looking back (without rewriting history)
We are not republishing every past meetup or release as a Blog article. Those already live on the homepage News, events, and resources pages. Where the past helps explain Unomi 4, we may write selective retrospectives that end with what to do today.
Start here
- Introducing Apache Unomi 4 — the major release story
- Unomi 4 for AI agents — customer memory for the agentic stack
- Migrating to Unomi 4 — API stability & REST compatibility for 2.x and 3.x
