ironfoil is a tool to transfer to many title installers. It exists as both a graphical application, ironfoil-gui, and a core command-line application, ironfoil.

Using the TinFoil USB protocol, it has been tested with Awoo Installer Switch and CyberFoil. It also supports Sphaira Switch with its own protocol, with Sphaira support enabled when transferring.
