Analista de Datacenter

Great solution to collaborate, network, and share documents & knowledge with your team thanks to powerful tools such as wikis, dms, forum.

A GREAT PLATFORM : eXo provides powerful collaboration tools that delivers a great user experience. Easy to start and navigate.

Program Manager

It was very easy to use and can be accessed anywhere in the world. Its price point is very competitive and customer service (at least for the free trial) was good.

Director of Operations

The software allows me to replace many solutions with a single integrated nice platform. I like the openness of the vendor is one of the biggest positive point for the choice I've made.

Student

There's a free version of eXo which comes with all the features. Couple that with a very supportive community and you get the best deal ever.

developer

I enjoyed eXo very much, as I enjoyed its special and very kind team, with whom I still talk on Skype or other instant messages services.

Manager

It's costly and heavy to load, I tried the open source version on my local server and  due to the tools used in development it loaded slowly. Also doing any customization is a pain.

Attractive interface and full of functionalities. Also excellent support from their community.

Executive Vice President, Worldwide Sales & Business Development

I like all the tools (social networking, collaboration, document management,...) are all integrated together. It delivers a great experience.

This great piece of software build on top of GateIn portal will give you all GateIn features (Content Management, Single Sign-On, LDAP support, etc) and much more.

Really like the ease of use of this solution. I was set in minutes and could start creating teams and projects right away.

A free product to socialize a company. Nice UI and easy to use, what else.

Founder

The amount of things on the page that demand the attention made me open a few tabs just to catch up with everything. Also, I found it hard to understand and how to actually get started.

It's easy to navigate all the features and start engaging others. It simplifies the relations and save time and money.

project management

You could have private Document Management , wiki or forum in each space. EXo has a great administration pane that let you manage users and define group and permission.

How is this open source. I saw no option to download it.

Creating customized pages and site is easy for admin. As an JAVA opensource platform you could customize every thing.

Java Developer

In Older version of eXo platform some time it distorts UI and UX but after releasing new eXo platform 4.1 version they are fixed and lots of new functionality added.

Mattermost

Software Developer

The incoming hook limitation of maximum content length is the hell (Mattermost don't inform the customer about a message which was higher above the hard coded message size limit).

Marketing Manager

What I like the most about this collaboration software is the simple and logical UI, which is not overloaded with lots of unnecessary features. It has all we need for successful communication.

Cross-platform applications ready to use. Amazing open source community built around the product, friendly and helpful people.

CEO / Lead Architect

The software is easy to use, similar to the commercial app Slack. It provides good thread tracking and the interface is clean and easy to understand.

Scrum Master 

I like how easy is to use and allows different "rooms" for collaboration for teams. It is a great tool for fast daily communication.

IT Security Engineer

Can be hosted on-premise. Good community support - Apps and Integrations brings great support to exchange data with external systems for software development teams.
