A while back I created Rails CRM. It was always meant to be a bare bones Customer Relations Management application as I did not find any that I liked.
I just released a beta version of Rails CRM – Advanced. It is still pretty bare bones but we have added a few new features and a new look as well. I am thinking of maybe providing a hosted solution for the new Rails CRM but I am not sure if there is any interest.
In the meantime, feel free to check it out at Rails CRM
As usual, this is open sourced and there are links to the Github repos on the front page.
