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.

Apply multiple classes in CKEditor stylesSet

I'm setting up the configuration for the Styles drop-down in my CKEditor, and am wondering if it is possible to apply multiple classes to a single element with a single style. The section of my stylesSet definition looks like this (note: this is a snippet and not the complete stylesSet definitio

Html cleaner config for Hippo 7.9

Hi all, I've been starting upgrading Hippo from 7.8 to 7.9 and face a problem that property "/hippo:configuration/hippo:frontend/cms/cms-services/htmlCleanerService/cleaner.config" doesn't exist. What should I do in Hippo 7.9 to set that parameters? Kind regards, Andrew.

Hi William, Thanks for your answer. I just copied the entire hippo:domains node from production to staging. So now I'm sure they are both identical. But I have still the same behavior. Thomas. Le jeudi 27 août 2015 14:07:31 UTC+2, w.borgbarthet a écrit : > > Hi Thomas, > > are you sure the

Hi Thomas, are you sure the hippo:configuration/hippo:domains are identical? Can you confirm this by replacing the entire hippo:domains on staging (make a backup) with the domains on production? That should exclude any differences due to security domains. William On 27 August 2015 at 05:01,

Re: [hippo-community] Trimming a database for local development
by: w.borgbarthet | 27-08-15 14:04:00 (CEST)

Hi there, you can probably safely truncate the REPOSITORY_JOURNAL table. Otherwise it's pretty hard to remove parts of the repository from the database level AFAIK. If you are doing local development, you might be better off using the default H2 file database and manually exporting and importing

Re: [hippo-community] FreeMarker template encoding not working right
by: Ramon Sistermans | 27-08-15 13:47:59 (CEST)

Hi, Jeroen solved this problem for us. :) The Freemarker servlet parses the .ftl using the platform's default Java encoding which for me (and most Windows users) is Cp1282. What worked was changing the file encoding system property in the root pom by adding it to the cargo-maven2-plugin
