A Native Bridge for Android. arm64 apps run on x86_64 hosts through Chimera's interpreter and translation tier, using Android's Native Bridge interface.
Chimera is a Native Bridge for Android: arm64 app code is loaded through Android's own guest linker and executed on x86_64 by Chimera's interpreter and translation tier, without a separate emulator beside the runtime.
It implements the Native Bridge interface Android has shipped for years, so x86_64 Android systems can integrate arm64 app compatibility as part of their platform.
Chimera is layered: a shared host runtime core plus thin platform frontends. The finished product has an Android/bionic frontend for AOSP devices and a Linux/glibc frontend so Drion can host arm64 Android apps on Linux with the same translator.
Runtime lifecycle, guest ELF loading, namespace policy, proxy dispatch, and execution-engine coordination live in a single core that doesn't depend on Android properties or glibc launcher assumptions.
An Android/bionic frontend exports libchimera.so as the system Native Bridge and ships into the system image alongside the guest ARM64 payload. The interface stays Android-native, so platform integration is explicit and testable.
Chimera brings up an interpreter first, then a translation tier with code caching. We're optimizing for apps that load and run unmodified — not for synthetic benchmarks.
ARM64 guest, x86_64 host, Android-shaped guest payload. Not a generic ARM64 userspace emulator. No ARM32. No x86 guest.
AOSP-based device builds and emulator products that need arm64 app compatibility on x86_64 hardware with platform-owned integration and validation.
Hosts running Android on x86 servers — including ourselves — that need predictable system-image integration and owned compatibility behavior.
LineageOS-class projects, research platforms, and vendor-controlled builds that need arm64 compatibility as part of their own platform stack.
Chimera is being actively built, but it is not available as a public release today. Join the waitlist for release updates.
We'll email when there is a meaningful product update or preview path. No drip campaigns.
