In their own words
Open-E JovianDSS
Open-E JovianDSS is Linux- and ZFS-based software-defined storage for NAS, SAN, backup, business continuity, and disaster recovery. It supports iSCSI, Fibre Channel, NFS, SMB (CIFS), and NVMe-oF, and can run on physical servers or as a virtual storage appliance in hyper-converged environments. Listed virtualization compatibility includes VMware, Proxmox, Citrix, and Microsoft Hyper-V. Its storage features include pools, unlimited scalability, unlimited file and volume size, and unlimited snapshots and clones. It supports shared-storage and non-shared-storage high-availability clusters, plus snapshot-based backup and replication for on-site and off-site protection. JovianDSS Up33 supports native ZFS encryption at dataset or volume level. Licensing depends on architecture and capacity: mirrored arrays use usable capacity, while parity arrays count disk capacity excluding cache and spares. Prices include a 670.00 USD one-time 0TB product license and a 670.00 USD one-time 4TB extension. A 60-day trial is offered; there is no free plan.
ZimaOS
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.
