ZephyrOS is a lightweight, Arch-based Linux distribution with a built-in AI assistant powered by Ollama. Choose an edition tailored to your workflow — every model runs locally on your machine, no cloud required.
A modern desktop experience with AI that respects your privacy and runs entirely on your hardware.
Every edition ships with an AI model via Ollama. Ask questions, write code, analyze logs — all offline, all private. No data leaves your machine.
Built on Arch Linux with Wayfire (Wayland compositor). Minimal resource usage means more RAM for your AI model and your work.
Full UEFI Secure Boot support with shim → GRUB2 → signed kernel chain. Your system is verified from firmware to desktop.
Windows 11-inspired design with a centered taskbar, frosted glass effects, rounded corners, and a beautiful dark theme out of the box.
5 editions tailored for different workflows. Each comes with curated tools and an AI model optimized for your use case.
Guided TUI installer walks you through disk setup, user creation, and configuration. Boot the ISO, click install, and you're done.
Each edition includes a full desktop environment, curated tools, and a locally-running AI model. Pick the one that fits your workflow.
AI-powered study companion. The AI acts as a patient tutor — explaining concepts, guiding problem-solving, and checking your understanding.
Full-stack development workstation. AI code assistant helps you write, debug, and review code across 6 languages with production-quality suggestions.
Security operations workstation. AI acts as a Senior SOC Analyst — triaging alerts, analyzing logs, and mapping to MITRE ATT&CK techniques.
For low-end hardware. A lightweight AI assistant with a minimal footprint — fast responses, small model, low resource usage.
The base desktop without a bundled AI model. Perfect if you want the ZephyrOS desktop experience and prefer to configure AI yourself.
From download to desktop in 4 simple steps. ZephyrOS includes a guided installer that handles everything for you.
Choose your edition above and download the ISO file. Each edition is a standalone bootable image — no other OS required.
Flash the ISO to a USB drive using Balena Etcher or Rufus, or attach it directly to a virtual machine (VirtualBox, QEMU, VMware).
Boot from the USB or ISO. A welcome dialog gives you the option to Install or Try ZephyrOS. The guided installer handles partitioning, user setup, and bootloader configuration.
After installation, reboot into your new system. On first boot, ZephyrOS automatically downloads your edition's AI model. Open a terminal and run zephyros-ai to start chatting.
ZephyrOS runs on modern x86_64 hardware with UEFI boot support.
