OpenNAS vs ZimaOS

OpenNAS is a free NAS operating system for managing files, storage, containers, and virtual machines through a browser-based desktop on your own hardware. It is based on Alpine Linux, targets x86_64, and is licensed GPL-3.0-or-later. File Station handles uploads and downloads, previews for common media and document formats, ZIP operations, recycle-bin restoration, and expiring password-protected public links. Storage tools show S.M.A.R.T. health, RAID status, and per-volume usage, and support disk initialization and configurable storage for virtual machines and containers. Container Manager handles Docker containers and 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 offers one-click self-hosted services such as Jellyfin, Nextcloud, Pi-hole, Vaultwarden, Gitea, Home Assistant, Portainer, and Immich. File sharing supports SMB/CIFS, NFS, and AFP, with Time Machine targets. The Free plan is free. The current installer is version 0.9.0-beta.1 for x86_64 and supports UEFI and BIOS boot; it requires compatible 64-bit x86_64 hardware, at least 2 GB RAM, and an 8 GB or larger USB stick.

ZimaOS is a NAS operating system for x86-64 hardware that combines file management, storage, backups, and apps. Users can manage, preview, and share files from phones, cloud storage, and external drives. Supported configurations include JBOD and RAID 0, 1, 5, and 6, while the backup system manages backup and sync across cloud, local, and LAN storage using a 3-2-1 strategy. Its App Store advertises more than 800 apps, with one-click installation and third-party Docker support; examples include Immich, Emby, Jellyfin, Plex, Home Assistant, and Nextcloud. It connects over LAN or WAN from PC and Mac and can connect with Synology and QNAP NAS devices. The maker says remote access uses encrypted peer-to-peer connections without internet ports open by default, and that local accounts collect no telemetry or user data. The free plan allows up to 4 disks and 3 members. ZimaOS+ costs 29.00 USD once for a lifetime license and allows unlimited disks and users. The license is bound to one device and may be transferred after at least one year of activation.
