CiviCRM's core system tracks contacts, relationships, activities, groups, tags and permissions, while additional components keep track of contributors (CiviContribute), events (CiviEvent), member lists (CiviMember), cases (CiviCase), grants (CiviGrant), campaigns (CiviCampaign), petitions (CiviPetition), bulk mailings (CiviMail), and reports (CiviReport). These components can be activated or deactivated to meet the needs of the specific organization.
CiviCRM is deployed in conjunction with either the Backdrop CMS, Drupal, Joomla! or WordPress content management systems (CMS) and is supported by many hosting and professional services companies. Both the Drupal and Joomla! professional associations use CiviCRM. CiviCRM's license is the GNU AGPL 3.

The app enables users to manage their contacts, calendar, cases, activities, events, contact payments and donations from their CiviCRM database.  The app also incorporates QR code ticketing for events.  Agiliway released its 4th version of the app in July 2019. 
CiviCRM is used by many large NGOs including Amnesty International, Creative Commons, the Free Software Foundation, CERN and the Wikimedia Foundation for their fundraising. CiviCRM is also used by Kabissa to provide CRM capabilities to over 1,500 organizations, mostly in Africa.
