GRAPHENE OS

GrapheneOS is an open source privacy and security focused mobile OS with Android app compatibility. Many past features of the project still need to be ported to the current releases. The project is in the 5th year of development and has been reborn as a non-profit open source project not strongly associated with any specific company or organization. It will take some time for the pieces to come into place turning it into a much broader and more sustainable project with a strong development team. There are multiple organizations and companies in the process of backing this new incarnation of the hardened mobile OS project. Official Releases are available on the releases page and installation instructions are on the install page.

See the GitHub organization for sources of the OS sub-projects including the cutting edge new hardened memory allocator.

The official GrapheneOS releases are supported by the Auditor app and attestation service for hardware-based attestation. For more details, see the about page and tutorial. You can also extend these with support for your own builds.

The sources are available via the manifest on GitHub.
