Sideloading Jailbreak Tools with AltStore

For iPhone and iPad users looking to explore the world beyond Apple’s default offerings, sideloading apps has become a powerful method to unlock more control. Tools like AltStore have revolutionized the way users install jailbreak apps and tweaks—without needing to jailbreak first.

But AltStore isn’t the only option.

While AltStore requires a computer and regular app re-signing, platforms like zJailbreak offer a simpler, faster, and no-computer-needed alternative to install jailbreak apps, themes, emulators, and even Cydia or Sileo.

This guide explores how to use AltStore to sideload jailbreak tools and compares it with zJailbreak, helping you choose the method that best fits your needs.

AltStore is an alternative app distribution platform for iOS, created by developer Riley Testut. It lets users install unofficial apps, including jailbreak tools, directly to their iPhone or iPad, without needing a full jailbreak.

It uses Apple’s developer provisioning system and refreshes apps using a companion desktop program called AltServer. This sideloading method is particularly useful for users wanting to try jailbreak tools such as Unc0ver, Taurine, or Fugu15, which are distributed as .ipa files.
