Cydia was created by Jay Freeman (saurik) in 2008. For over a decade, it was the default package manager for almost every jailbreak.
Developed by the Electra Team (CoolStar), Sileo was built from the ground up as a modern replacement for Cydia. Written in Swift, it is faster, supports native dark mode, and handles modern APT 1.8+ features. Most new jailbreaks (Chimera, Odyssey, Taurine) ship exclusively with Sileo. cydia installer repo sileo
Pro Tip: If a tweak you loved from Cydia doesn’t appear in Sileo’s search after adding BigBoss, check the package’s compatibility. Tweaks from iOS 9 era will not work on iOS 14/15 without updates. Cydia was created by Jay Freeman (saurik) in 2008
