Why napp-it?

The six things that set napp-it apart from other storage solutions.

01

Web-GUI — single server to whole serverfarms

Manage one machine or an entire fleet from one central web interface. No agents, no extra VMs.

02

Runs on FreeBSD, Illumos, Linux, macOS, Solaris & Windows

True cross-platform: one GUI for every major server OS. Mix and manage them all together.

03

Storage Spaces, S3 Object Storage & ZFS

Storage Spaces (Windows), S3-compatible object storage and Illumos-/Open-/Solaris-ZFS — all in one.

04

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.

05

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.

06

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.
