AvdanOS

AvdanOS is a free, open-source, Unix-like operating system focused on simplicity and modularity for desktops, laptops, and embedded devices. The project aims to provide a cohesive, secure, and easy-to-use platform while remaining portable across architectures. AvdanOS was initiated by Avdan Technologies in 2022 with a goal of delivering a lightweight alternative to larger distributions. The core is a modular kernel with a traditional monolithic design and a capability-based security model, offering support for x86-64 and ARM64, with ongoing experimental ports to RISC-V.

The userland includes a small set of essential utilities and the Avdan Desktop Environment (AvDE), which provides a streamlined graphical interface. A cross-platform package manager, Avdan Package Manager (APM), handles installation, updates, and sandboxed builds, and a separate snapshot system allows rollbacks.

AvdanOS ships with an init system designed for fast boot times and straightforward service management, along with built-in hardening features such as user namespaces, mandatory access control policies, and black/white-list based application permissions. The distribution emphasizes security defaults and straightforward configuration.

Developers release new versions on a roughly six-month cadence, with major releases offering extended hardware support and improved power management. The project is distributed under an open-source license, with source code hosted on public repositories and contributions accepted from volunteers and organizations.

Reception to AvdanOS has been cautiously positive in niche communities and educational settings, particularly noting its clean design and documentation, while some users request broader hardware compatibility and a larger software ecosystem.
