Everything you need from a NAS — without the license fee.

Boots from USB

The OS lives on the USB stick alongside your persistent config. No internal disk wasted on the operating system.

Web UI

Full management interface in the browser, no monitor or keyboard required after first plug-in.

SnapRAID parity

Scheduled parity protection with up to 6 parity disks, plus a mergerfs unified storage pool.

Docker

Install and manage containers from the UI. Bring your own compose, or use the bundled templates.

Samba + NFS shares

Per-share permissions for Windows, Mac, and Linux. Public, password, or per-user access.

Unraid import

Drag in your existing Unraid backup zip — shares, disk assignments, and Docker containers come with you.

One-click updates

In-place updates from the Settings page. Your array data and config are never touched.

Email + webhook alerts

Get notified about array degradation, disk temperature, and parity check results via SMTP, Discord, or Slack.

Free for personal use

No license servers, no device caps, no nagware. Free for personal and non-commercial use.
