Your data. Your hardware.
Your rules.
Brain NAS is a complete NAS operating system that boots from USB. Enterprise-grade features, dead-simple setup. No cloud required.
Everything you need. Nothing you don't.
All features included in every tier. Only the number of disks differs.
Flexible Storage
MergerFS pools your drives. Mix any sizes and brands. Add or remove disks anytime without rebuilding arrays.
Parity Protection
BrainParity protects against drive failure. Lose a disk, rebuild from parity. Block-level with offset support.
Encryption
Full-disk encryption with LUKS. Your data stays private even if someone steals your drives.
Docker Apps
Run any Docker app from the built-in app store. Plex, Nextcloud, Home Assistant, and hundreds more.
GPU Passthrough
Pass your NVIDIA or AMD GPU to Docker containers for hardware transcoding, AI workloads, and more.
Enterprise VPN
Built-in WireGuard VPN with kill switch, DNS leak prevention, and IPv6 blocking. Access your NAS from anywhere.
