UNIXi

UNIXi is a family of Unix-like operating systems designed to be portable across hardware platforms and fully compatible with the POSIX standard. Developed as a contemporary successor to classic UNIX variants, UNIXi aims to provide a stable, secure, and maintainable environment for servers, desktops, and embedded devices. The project is coordinated by the UNIXi Foundation.

UNIXi originated in the early 2010s as a collaborative effort to modernize Unix heritage while preserving familiar userland interfaces. The first stable release, UNIXi 1.0, appeared in 2012, followed by periodic major releases that introduced new features, compatibility layers, and developer tools.

Its kernel implements a modular, hybrid design with loadable modules and a robust memory management subsystem. UNIXi emphasizes a clean separation between userland and kernel space, a conventional init system, and a standard set of utilities. It includes a packaging system, container support, and filesystem interfaces intended to support snapshots, file permissions, and multi-user isolation across architectures.

UNIXi is distributed under a permissive license that encourages open development and redistribution. Official builds are produced by the UNIXi Foundation and partner distributors, while community-driven ports extend support to additional hardware architectures and specialized environments.

The UNIXi ecosystem parallels other Unix-like families, influencing security practices, system administration tooling, and educational curricula. As of the early 2020s, UNIXi maintains ongoing development with regular updates, though it remains a minority platform outside particular enterprise and research contexts.
