Immutable. Lightweight. Blazing Fast.
AvyOS is an immutable Linux distribution built from scratch using OSTree, optimized for speed, stability, and a beautifully customized XFCE desktop.
AvyOS is an independent operating system based on Linux kernel designed for long-term stability and reliability. The name comes from the Sanskrit term Avyaya (अव्यय), meaning “unchanging” or “immutable.” AvyOS protects the core system from accidental changes and delivers safe, predictable updates using OSTree.
OSTree-based immutable system that prevents accidental breakage.
Built from scratch and optimized for real, noticeable speed.
Lightweight, responsive, and beautifully tuned desktop environment.
Run apps from any distribution without touching the base system.
Add drivers and desktops safely without compromising stability.
Immutable architecture enables safe rollbacks and recovery.
A beautifully customized XFCE desktop lightweight, responsive, and optimized for speed without sacrificing aesthetics.
Clean XFCE layout with custom theming and fast panel response.
Fast, minimal app menu designed for keyboard and mouse users.
Instant app launches and low resource usage on real hardware.
Immutable Linux distributions keep the core operating system read-only and consistent. Instead of modifying the live system package by package, the OS is built and tested as a complete image and updated atomically. This prevents partial upgrades, dependency conflicts, and system breakage.
AvyOS embraces these trade-offs while restoring flexibility through Flatpak, Distrobox, and controlled system extensions keeping the base stable without limiting user workflows.
Most Linux distributions assemble systems from independently built packages. Even when versions are frozen, those packages are rarely built or tested together as a single, unified system.
AvyOS uses an image-based build process where the entire system is integrated, built, and validated in one pipeline. This eliminates subtle incompatibilities and prevents package-level breakage.
The result is a system that remains stable and predictable across updates aligned with the meaning of Avyaya: that which does not change.
AvyOS makes deliberate design choices to ensure stability and consistency. These limitations are intentional and rarely affect day-to-day usage.
AvyOS is not based on Debian, Fedora, or Arch. As a
result, system-level package managers like
apt,
dnf, or
pacman
are not available.
Instead, applications are installed using Flatpak or Extensions and full development environments can be created using Distrobox.
The root filesystem (/) is read-only by default. This prevents accidental
system modification and keeps the OS in a known,
reliable state.
Most users never need to modify the root filesystem. Configuration, applications, and development workflows live outside the immutable base.
These constraints exist to protect the system. AvyOS prioritizes stability at the core, while providing flexibility on top so you can focus on using your system, not fixing it.
AvyOS is a community-driven, open-source Linux distribution. Whether you write code, test builds, design interfaces, or document systems your contribution matters.
