Web-based
ZFS NAS/SAN
Appliance
Full storage management for OmniOS, Proxmox and Windows — with the best ZFS and SMB integration available. Free for home users.
Why napp-it?
The six things that set napp-it apart from other storage solutions.
Web-GUI — single server to whole serverfarms
Manage one machine or an entire fleet from one central web interface. No agents, no extra VMs.
Runs on FreeBSD, Illumos, Linux, macOS, Solaris & Windows
True cross-platform: one GUI for every major server OS. Mix and manage them all together.
Storage Spaces, S3 Object Storage & ZFS
Storage Spaces (Windows), S3-compatible object storage and Illumos-/Open-/Solaris-ZFS — all in one.
Base for "build your own branded" web-GUI
napp-it is a foundation — sublicense it, brand it. Build a custom NAS GUI on a proven Perl core.
AI/Claude-friendly — extend, debug, audit, help
Built-in guideline, docs and behaviours make it easy for AI assistants to understand, extend and audit the codebase.
Free for home use, cost-efficient for commercial use
Free for a single server or up to 3 servers at home. Pro licenses for commercial use are priced to stay affordable.
ZFS — the safest filesystem
Two paths to the perfect NAS
Choose the edition that fits your infrastructure — both offer complete ZFS management through a modern web interface.

Everything a NAS needs
Complete storage management from one web interface.
ZFS Snapshots*
Instant snapshots with no performance overhead. Schedule automation. Replication to remote servers.
Replication*
ZFS replication from any server to any server. Incremental, efficient, optionally encrypted.
Data Security*
AES-256-GCM encryption. Keyserver integration. Checksums on all blocks. Automatic healing.
S3 Object Storage (Preview)*

User Management*
Local users, Active Directory integration (SE). Quotas, SMB shares with Windows SIDs as native ZFS attributes.
Hybrid Storage*
Flash storage is small and expensive. Hard drives are large and affordable. ZFS hybrid storage with Special Vdev mirrors combines both — flash for performance-critical data, HD for the rest.
Monitoring*
Real-time performance. Disk health via S.M.A.R.T. Enclosure Maps for JBOD. Network virtualization.
The right license for every use case
