Cydia is an open source software installer created by saurik that uses the Debian APT system for package management. It is found in every mainstream jailbreak tool since iPhone OS 2.0.
Some older jailbreak tools install smaller apps (such as Loader.app for greenpois0n or blackra1n.app for blackra1n and limera1n) to download and install Cydia directly on the device instead of having it installed at the same time as jailbreaking, making for a lighter initial download and jailbreak.
Cydia's latest version is 1.1.27, which supports all devices (except Apple TVs and Apple Watches) running iPhone OS 2.0 - iOS 9.3.3. The translations package (
cydia-lproj), however, hasn't been updated since 13 June 2014 (1.1.12).
As a frontend for APT, Cydia allows users to add/remove repositories where they can install packages. By default, Cydia includes the third party repos BigBoss, ModMyi, ZodTTD/MacCiti and repo666.ultrasn0w.com, as well as its own Telesphoreo repo.
