Valve has made Lepton, the compatibility layer for running Android games on the Steam Frame, open-source. The project is available on Valve's GitLab repository and aims to assist game developers in bringing their VR Android games to the Steam Frame. Lepton combines Valve's proprietary code with components from Waydroid, Anbox, Halium, and Hybris, as well as portions of the AOSP. Open-source developers may utilize Lepton's code, adapt it for various applications, or fork the project to introduce new features or optimize its functionality.
