If I understand the chart correctly, there are 9865 websites that user neither of the listed CMS. So what CMS do these 98.7% use?
Hi Hans,
Interesting observation. As you can find on other category pages on this website, some of them are based on Blog Software (215 of them) and some on Forums (309). That still leaves 9341, or 93%, unaccounted for. What could they be based on?
1. Other systems not (yet) covered by our website. I need your help here. If you know of any that's missing, please let me know.
2. I believe though that the majority of websites are not built on any out-of-the-box software package. Instead they are built on custom code. This could still include some under-the-hood framework (Zend, Ruby on Rails) or isolated third-party libraries. I'm planning to add data to this site on what server languages are most in use (eg PHP, .Net etc). This will say something about all these websites.
I've stumbled across one, its called textpattern.

I did some poking around a year ago - made a crawler that could detect around 35 of what I believed were the most popular CMSs in the markets I was investigating - both commercial and open source system. I then bought lists with urls to the 10.000 biggest companies/organisations web sites and checked their sites. Still could only identify around 50%. It's would be interesting to really find out exactly how many web sites are build on custom technology today - and how many use some sort of of-the-shelf CMS.
Needless to say, my numbers where not exactly like what you are showing on this chart - but it's still good work. It gives a pretty decent indication of how the open source non-microsoft-based CMS market is distributed.
Im shocked that wordpress isnt on this list?
You can find Wordpress under Blog software. Categorizing software is not always easy. In this case, while Wordpress offers some CMS functionality, its quite limited and really mostly meant to be used for blogs. Do you disagree?
Great information.
Thanks for sharing these info with us!
I will keep in touch with your blog reading...
I can't believe CodeIgniter isn't on this list...
