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".

I've used community builder for over 6 years now, and I am still ecstatic over their products! Regardless if I'm working for a client or myself, if I'm building membership sites, social networking sites, normal Joomla websites, or complex advanced sites community builder is always the first extension I install! The flexibility is amazing, the features unique, and the support leaves me breathless! It has a learning curve, but the time invested is well worth it! Then you'll be just as addicted as I am!

worth the investment

Posted on 21 February 2014

I used CB in the free edition and were quite happy. So I decided to go for the paid Pro version when my needs for a more sophisticated setup grew. The Investment was quite substential but I have to say the support and the additional extensions which made me reach my goals with ease brought back the smile.

There are still some bumps in the code, like they dont have a language override system in place (they dont use the Joomla native language feature) which makes it (almost) impossible to have your own customised language strings. But they are working on it already.

Keep on rocking guys!
