AXRB

AXRB runs Android XR applications on Windows and presents them through a desktop OpenXR runtime such as SteamVR. Android runs in a hardware-accelerated x86_64 emulator. ARM64 applications are translated inside Android, while GLES and Vulkan rendering use the host GPU. Frames are transferred to the Windows compositor with shared GPU textures.

AXRB is a compatibility runtime, not a replacement for Quest OS. Some games require features that are unavailable or behave differently outside the Quest system, including proprietary platform services, hand or body tracking, protected media paths and title-specific shaders. The launcher reports failed Meta requests and incomplete downloads instead of treating them as successful.

The project does not bundle commercial games, ovrport, Meta credentials or Quest content. Users must supply games they are entitled to use.

• A Windows launcher for the AXRB runtime and installed Android games.
• Meta Quest library and storefront integration for owned Quest applications.
• Downloads for Quest APKs, split APKs, OBB files, expansion assets and eligible DLC.
• Import of local APKs, patched APKs and ZIP packages containing game files.
• Android 16 runtime support with ARM64 translation.
• OpenXR presentation to SteamVR, including stereo layers, dynamic layer storage, controller input, tracking, audio routing and application identity.
• GPU-backed Vulkan and OpenXR frame transport instead of software rendering.
• Shared runtime policies for Unreal texture memory and other compatibility behavior, without game-specific patches in the launcher.
• Optional FPS HUD, preview window and save-aware game shutdown.
