Fugu15 is a semi-untethered, permasigned jailbreak for iOS 15 that combines a code-signing bypass, kernel exploit, kernel PAC bypass, and PPL bypass. It can be installed directly via Safari without a computer and ships with the iDownload shell, but does not support tweak injection.

Use cases

  • jailbreak an iPhone running iOS 15
  • install a jailbreak via Safari without a computer
  • gain root access on arm64e iOS devices
  • access a root shell on iOS via iDownload
  • research iOS kernel exploits and PPL bypasses
  • permanently sign a jailbreak app on iOS 15

When to choose

  • you have an arm64e device on a supported iOS 15.x version and want a semi-untethered jailbreak
  • you want to install a jailbreak over the network via Safari without connecting to a computer
  • you are a security researcher studying kernel, PAC, or PPL bypass techniques on iOS 15

When to avoid

  • you need tweak injection or Cydia/Sileo tweak support, since Fugu15 ships no tweak injection library
  • your device is not arm64e (e.g. iPhone X or older)
  • you are on iOS versions outside the tested 15.x range
  • you want a fully untethered or one-click consumer jailbreak with broad device support
