A CMS framework that makes sense
Powerful. Intuitive. Flexible. concrete5 is a free open source content management system written in PHP. Check out a beefy feature list in our documentation, or learn more about what makes concrete5 unique below...
Build Powerful Sites
Professional tools that are easy to use
concrete5 is MIT Licensed Open Source and uses jQuery, ADOdb, TinyMCE, and Zend Libraries that you’ve grown used to working with. Sure it’s easy for anyone to start building a simple site with our in-context editing, but concrete5 has a really powerful advanced user/groups permissions system, a flexible data objects model, and built-in helper classes as well. Generally we’ve tried to make concrete5 easy to understand at a glance, but super powerful when you get under the hood.
Easy to Extend
Built for WCM from the bottom up
Every concrete5 install has a nicely encapsulated core directory you never have to touch. You can safely override core files, and still automatically apply an update later. Our MVC approach to blocks and single pages let you quickly build flexible applications. Our marketplace of add-ons have all been vetted, come with clear support expectations, and won’t break your site.
Happy Clients
It's a pleasure to use concrete5
Clients actually enjoy using concrete5. We’ve had clients adding content to their sites before we even showed up to train them. We don’t get frantic calls demanding we post a press release for our clients at 4:50pm, they just do it themselves. Wouldn’t you like to have clients who loved their websites instead of simply putting up with them?
Get Started
Let's see how it works.
If you already have a hosting account somewhere, ask your hosting company to help you get concrete5 installed. If you'd like to just play with a copy immediately, you can setup a trial on our servers to play around with for 15 days at no cost.
