Cuttlefish is a configurable virtual Android-powered device that runs locally or remotely. It is intended for platform and app developers who need to develop and validate code changes without relying on physical hardware. The device aims to reproduce Android framework behavior closely, including custom framework implementations. Users can set its form factor, RAM, and CPU count, then run multiple devices at once with concurrent test execution. Documented uses include CTS, framework compliance, continuous integration, and custom test suites. Cuttlefish runs locally on Linux x86 and ARM64 machines and requires host virtualization with KVM. It registers with adb as a normal device and can be viewed and controlled in a browser through a local WebRTC webview. It natively supports Google Cloud; support for other cloud platforms is described as planned. Differences from physical devices mainly involve the hardware abstraction layer and software that interacts with custom hardware. Cuttlefish is free and open source, and its documented setup requires Debian host packages plus device images and a host package from Android Continuous Integration.
