QEMU vs Waydroid

QEMU is a free, open-source machine emulator and virtualizer. System emulation models an entire machine, including its CPU, memory and devices, so it can run a guest operating system. User-mode emulation runs processes built for one CPU architecture on another. The package also includes qemu-img, a command-line utility for creating, converting and modifying disk images. QEMU can work with KVM, Xen and Hypervisor.Framework so guests can run directly on the host CPU. Supported build platforms include Linux, macOS, FreeBSD, NetBSD, OpenBSD and Windows. Windows support is limited to 64-bit, while macOS requires the newest version currently available; support for the prior version is eventually dropped. For complex networking and storage configurations, the project recommends management tools such as virt-manager. Its security guidance distinguishes virtualization with an accelerator and listed machine type from TCG non-virtualization use, which does not provide guest-isolation or security guarantees. QEMU is released under GNU GPL version 2, with some components under specific licenses.

Waydroid runs a full Android system inside a Linux container on GNU/Linux computers using Wayland desktop environments. Its customized runtime image is based on LineageOS and Android 13, supporting ARM, ARM64, x86 and x86_64 architectures. Android apps can appear in the Linux applications folder, with multi-window mode or the full Android interface available. The command line installs, removes, launches and lists applications, including APK files. Installation documentation covers Fedora, Void Linux, Debian and Ubuntu derivatives, with community guides for other distributions. Documentation also explains ADB setup and shared folders between the Linux host and Android container. Google Play support comes through Gapps builds containing Google Play Services and the Play Store; those builds are not suitable for commercial use without applicable licensing. Waydroid is free and open source under GPL version 3, while commercial licensing can be arranged by contacting the project. Educational licenses are available to qualified students and educators. Nvidia GPUs other than Tegra and virtual machines should use software rendering.
