Open and free
CiviCRM is open source, which means free to download, install, modify and share. It relies on reinvestment by those who benefit from it to continue to be innovative, robust and non-commercial.
The CiviCRM Starter kit is maintained by Herb v/d Dool. There is no official link nor endorsement between this site and the CiviCRM project. This site was originally built by John Derry with loads of contributed code from the CiviCRM and Drupal communities.
