About Xlings

xlings describes itself as universal package infrastructure with OS-like SubOS isolation. The goal is a single tool to install any version of anything, run it without root privileges and isolate it, across Linux, macOS and Windows, with a decentralized package index and readiness for use by AI agents.

The README distinguishes three separate questions about support: whether xlings itself has a release for a platform, whether a given package has an artifact for that architecture, and how much isolation the sandbox option provides. Linux x86_64 has the fullest support, with filesystem isolation through bwrap or proot, while Linux aarch64, macOS 14 and later on arm64 and Windows x86_64 have partial package coverage. On macOS and Windows the sandbox only redirects the home directory so tools write their dotfiles somewhere isolated and is explicitly not a security boundary.

Package coverage depends on each recipe, and installation refuses a target only when the recipe lists architectures that exclude yours. xlings is written in C++, licensed under Apache-2.0, comes with documentation, a package index and a forum, and is used by projects such as MCPP.
