Just fantastic

Awesome feature set and plugins for pretty much everything

Ease of use

Pretty snappy user interface; well laid out and easy to get around



I used this to: I bought this mostly because I needed something that would let me get a lot more info from my users when they register. And because of all the additional functionality it provides Joomla. I tried a few other products but just not as comprehensive as CB. Love it!


CB offers us exactly what we need: managing members, lists of different member groups, etc.

Ease of use

Kinda involved for the novice, but not horrible. Just takes some getting used to.


Support for free stuff is kinda iffy, but the forum is fabulous for digging out your own answers. I've found most of my issues solved there.


You have to pay for the documentation manual, which is a downer. OTOH, the forum provides lots of information on issues that arise.

I used this to: two membership sites, one pay, one free. On the pay site, CB allowed us to set up an application with three membership groups, create member lists for each group, integrate with Kunena. Makes our job in managing members MUCH easier.


The quality and custom-ability of the code exceeds my expectations every time. They seem to think of everything, or consider many uses.

Ease of use

There are very simple scripts I've implemented and more complex configurations... and I am still a novice with Joomla!, more of a designer.


I've been using Community Builder for over five years and it is really unparallelled in quality of the code and level of support included.


With thorough, easy-to-find / downloadable documentation, you also get video tutorials and a very good, well organized and manage Forum!

I used this to: I like using CB every change I get on a variety of websites! It adds the interactivity that visitors and users like. Such as setting up profiles, sharing and connecting documents and posting updates. It's a value added element for clubs, artist guilds, & other similar interests.


Community Builder gives you a full featured user database foundation.

Ease of use

I had trouble migrating from Joomla 2.5 to 3.3, but that was mostly my fault. I know how to do it better now. The new system is great.


I haven't needed support, the system works so well.


There are online guides from others to step you through, and Joomlapolis has videos, too.

I used this to: I have a database of over 4,000 users. This allows our users to update their profiles, lets us maintain annual training statistics, and gives our members options to participate on the site.

Joomla and Community Builder are so perfect together, they should be married :-) CB is fantastic, support is awesome, control is great.

I use Community Builder and extensions on a lot of websites for many years and it is really a very good product to build complex communities. During the years they do a lot over very powerfull usefull upgrades, like auto actions etc.

They support is the best of the best and quick. I suggest this

Top extension

Posted on 17 October 2014

I am building the website for a small dojo association and was looking for an extension to add custom fields to users profile when they register.(like their sensei name, dojo location, etc) I must say Community Builder made that pretty easy! I got the advanced subscription to support the team and get the whole documentation. After fiddling a bit more with CB, I found out it is a very flexible solution. But with flexibility often comes complexity, so I was glad to see that the documentation was very well written and complete. I found out about the privacy plugin feature for fields and how to add private tabs, etc. All in all, we managed to build very nice profiles for our users, and we are now looking at the other features like private messaging and allowing users to post their own blog and gallery.

What I also truly appreciated is that, while I am no programmer, I suspect CB API is really easy to use because of the amount of extensions that provide a plugin to integrate to CB profiles. CB itself is also pretty stable. I can't speak for 2.0 since it's been out for only a few weeks, but v1.9.1 ran without a hitch without problem.

And finally, the support. I got nothing but praise for it. While sometime I didn't like the answer(like: "This will be fixed in CB 2.0" which was months away back then) they have ALWAYS answered within 24 hours on their forums. The memberships price are not cheap(but you can get the basic extension itself for free), but I am glad I took one as a "thank you" for this great extension. It is unique in it's field right now, and v2.0 fixed the only small annoying things I had to say about it(the registration form and login box were not responsive so it would not display correctly on a tablet or phone. All fixed now). 5 stars

Excellent code and functionality!

The support is superb too!

And the paid plugins like Groupjive have no comparison.

I've been using it for years and by far is the best joomla component to create social networks

We have been using Community Builder in our sites for over 7 years now and we have always loved the great features CB brings to our Hobby based sites.

The support from the CB team is top notch, and we always get an answer to our questions in a timely manner.

We are Professional level members because of the added plugins and enhancements they add to the site. If you are looking to offer outstanding features to your sites members this is the only way to go.

Also the direction of the CB project is great with the soon to be stable release of CB 2.0, cant wait for the new version to be used on all our live sites.

Way to go CB Team, keep up the great work!


I have been using CB since 1 year. This component is Superb! I used it to create a dating site, a corporate intranet & now the community for a sport steam.

It is really a very good product to build complex communities. It is very Flexible and easy to install

There are endless possibilities that also shows in countless other components that include "CB integration".
