In their own words
TrueNAS
TrueNAS Community Edition is free storage software that provides file, block, and object storage through one interface. It uses ZFS capabilities including snapshots, replication, RAID-Z, and self-healing checksums. Listed services include SMB, NFS, iSCSI, S3 API compatibility, apps, Docker containers, and virtual machines. Administrators can manage it through a web UI or CLI and use SNMP, syslog, reporting, and the TrueNAS API. Security options include self-encrypted drives, dataset encryption, encrypted replication, WireGuard, OpenVPN, ACLs, and IP filtering. The maker lists integrations or certifications involving Kubernetes CSI, Proxmox, VMware, Veeam, Red Hat OpenShift, and others. The Community Edition is a free software download for x86 hardware, with support through forums, documentation, release notes, and bug ticketing. Professional support is described for Enterprise customers. TrueNAS publishes security advisories and recommends configuring systems according to its security best practices. Moving from TrueNAS CORE to Community Edition is a one-way upgrade.
ZetaNAS
ZetaNAS is an open-source network-attached storage platform for SMBs, startups, and teams running AI or machine-learning workloads. It combines file sharing, collaboration, and data pipelines with native S3 and POSIX access, plus NFS/PNFS support. The system runs on mainstream x86 or ARM hardware and can expand from one server to distributed clusters. Built-in deduplication, erasure coding, and intelligent compression are described as reducing physical storage use by 30% or more. Security and reliability features include EC replication, disk-health monitoring, fault isolation, access control, and auditing. Media tools provide multi-device sync, version history, previews, and chunked transfer. Shared workspaces add real-time synchronization and granular access control. Medical deployments support DICOM and WSI data, annotation, and quality control. AI workloads can stream through S3 and FUSE to GPU nodes. A Docker-based app store manages extensions.
