Summary
OpenNAS is a free NAS operating system for managing files, storage, containers, and virtual machines through a browser-based desktop on your own hardware. File Station handles uploads and downloads, previews for images, video, audio, and several document types, ZIP operations, recycle-bin recovery, and expiring password-protected public links. Storage tools show S.M.A.R.T. health, RAID status, and per-volume usage, and let administrators initialize disks and configure space for virtual machines and containers. Container Manager works with Docker containers, images, logs, resource statistics, and docker-compose stacks. KVM/QEMU virtual machines support ISO booting, qcow2 disks, and an in-browser noVNC console. Package Center includes one-click self-hosted services such as Jellyfin, Nextcloud, Pi-hole, and Home Assistant. OpenNAS also supports SMB/CIFS, NFS, and AFP sharing, along with Time Machine targets. It is based on Alpine Linux, licensed GPL-3.0-or-later, and targets x86_64. The current installer is version 0.9.0-beta.1; it supports UEFI and BIOS boot. The Free plan is 0.00 USD per free.
Who it is for
OpenNAS suits self-hosters who want to manage shared storage, containers, and virtual machines on their own compatible x86_64 hardware. It requires a compatible 64-bit system, at least 2 GB RAM, and an 8 GB or larger USB stick for installation.
