Opensource CSM is an awesome website that easily gives you demo access to the front and back end of various opensource cms projects out on the web. I am a big fan of open source projects and this is like a playground for me!
I was curious about how Magento worked but didn’t want to go thru the trouble of installing it on my server just to try it out.
Opensource CMS had a live demo copy of Magento that I could access as if it were installed on my own server without having to do all the work.
Each featured CMS on the website has a commenting system and a rating system to allow web designers and developers to interact and make suggestions to one another.
If you happen to be a developer and are building an opensource project and would like to get the word out about your project you can request to have it include in the website.
Give OpenSource a look, its a fun place to waste time and maybe find a CMS you may fall in love with!
