What is Hippo CMS?

Hippo CMS is an open source Java CMS. We built it so you can easily integrate it into your existing architecture.

Open Platform

We are big believers in open source. We use and contribute to many open source components - and our entire core is available under the Apache License

Java Stack

What you'd expect from a Java environment: easy to integrate, testable, ready for continuous integration, and sticking to familiar Java standards such as JCR 2.0 and JAX-RS


Highly scalable platform which supports both clustering and replication


Performance matters to us! Hippo CMS  scales both  horizontally and vertically and makes use of  multi-layered caching to squeeze the most out of your implementation


Query content using REST, or import content from somewhere else into Hippo. Hook up an external application into the rendering phase via Spring. Build a Mobile app or an AngularJS app that consumes content from Hippo. Use external data systems to feed our personalisation engine


Protect your content with fine grained authorizations,  LDAP support and secure replication

The CMS Features You'd Expect

Content editing, workflow, history, version control, image library, user management, out of the box

Multi-lingual, Multi-site, Multi-channel

Out of the box support for multi-language, multi-site and multi-channel implementations. Cross-domain, cross-site, cross-language and cross-channel linking between documents are resolved automatically.

Separate Content from Presentation

Break free from page oriented development. Redesign your website without modifying content and reuse your content across websites, mobile  apps, etc. Use Hippo's  fully customizable document oriented model and built-in modelling tools to separate content from presentation.


Deploy on-premise or in the cloud on your preferred servlet container

Extensible Components

Use or extend existing components from the Hippo Feature Library or build your own. Use JSP, Freemarker or AngularJS to render your components

Give Control To End Users

End users can manage page configurations, menus, URL structures and component mappings. Without you having to go into code


Deliver personalized pages to visitors with the Relevance module


We don't mess with your HTML output. Use whatever web framework you like; Bootstrap, AngularJS, it's up to you


Out of the box querying, facetting and full text search capabilities based on Apache Lucene - or hook up Elasticsearch if you need more power


Can I try it out?

Yes! Try the online demo of  Hippo Enterprise Edition or create your own  project with Hippo Community Edition.

Look under the hood if you like, we share our source code.

by: b.leunis | 06-07-15 16:19:49 (CEST)

Hi Vlad, Are you using the Rest service feature of Essentials? I believe that the setup used for that is not built for serving XML. It was originally built for 7.9, and is using HippoBeans instead of Representations. 7.9 had a restriction on using HippoBeans and exposing the output as XML. That

Hey Jeffrey, from code, you can access the profile for the current visitor via com.onehippo.cms7.targeting.ProfileProvider#get . From 10.0 and higher the previous method is deprecate (still works), you should use TargetingStateProvider.get().getProfile(), also see [1] and [2]. From TargetingSt

How to determine whether a catalog component has been trigged by the Targeting & Relevance module
by: Jeffrey Houben | 06-07-15 14:10:12 (CEST)

Hi, We were wondering if there is a method to determine whether a catalog component has been triggered by the Targeting & Relevance module and if so, which Persona and/or Target Group was responsible for the trigger. So we actually want to be able to have access to this information from inside
