BOINC provides documented interfaces making it possible to develop various types
of applications and web sites
that interact with BOINC components.
Examples include:

 * [GuiRpc Client GUIs]: Applications that control a local or remote core client.
 * [CreditStats Credit statistics web sites]: Web sites showing credit information (project totals, user/team/country leaderboards) based on daily XML feeds of statistics data from BOINC projects.  The XML format is documented [XmlStats here].
 * [AccountManagement Account managers]: Web sites that let BOINC users create and manage accounts on multiple projects.
 * [StatsXml Aggregate credit statistics]: Web RPCs for getting cross-project credit data for hosts, teams and users.
 * [WebRpc Web RPCs]: These interfaces let a program or web site obtain information about projects, and create/edit entities (users, teams, hosts) on projects.
 * [PrefsOverride Local editing of preferences]: This mechanism lets you write programs for local editing of preferences.
