What redroid is

redroid runs Android in containers on Linux, with GPU rendering options and support for multiple instances. The project describes cloud gaming, virtualized phones, and automation testing as possible uses. It can run on Linux hosts through Docker, Podman, or Kubernetes and supports arm64 and amd64 architectures. Documented images span Android 8.1 through Android 16, including 64-bit-only variants for Android 12 and later.

GPU rendering can use software rendering, host GPU acceleration, or automatic detection. Users can configure display width, height, frame rate, and DPI; documented defaults are 720×1280 and 320 DPI, with 30 FPS using GPU rendering or 15 FPS without it. The documentation describes running ARM apps in x86 instances with libhoudini, libndk_translation, or QEMU translator; published images include libndk_translation. Google services can be added through Open GApps, MicroG, or MindTheGapps. The quick start uses Android Debug Bridge to connect and scrcpy to view the instance screen. Deployment requires Linux kernel features including binderfs, ashmem or memfd, IPv6, ION or DMA-BUF heaps, and 4KB page size. The project warns that exposing the ADB port publicly can compromise the container and host OS. redroid is free open-source software under Apache License, while its kernel modules are under GPL v2.
