napp-it vs OpenNAS

napp-it is a client-server web GUI for managing storage on one machine or across server fleets. It supports in-house storage servers and clusters, S3 cloud servers, and AI providers. Its central interface runs on FreeBSD, Illumos, Linux, macOS, Solaris, and Windows, and can manage servers without an agent or extra virtual machine. Sharing protocols include SMB, NFS, S3, iSCSI, and Fibre Channel. ZFS capabilities include AES-256-GCM encryption, end-to-end checksums, snapshots, automatic healing, and optional real-time deduplication. Replication is incremental, can link arbitrary servers, and can be encrypted during transfer. The S3-compatible endpoint works with Nextcloud, rclone, backup tools, and MinIO clients. Monitoring covers performance, disk health through S.M.A.R.T., JBOD enclosure maps, and network virtualization. CS Home is free for noncommercial home use, allows up to three servers, and includes no support. SE Free allows commercial and home use but excludes individual support and Pro features. A new installation includes a 30-day evaluation of Pro features.

OpenNAS is a free NAS operating system for managing files, storage, containers, and virtual machines through a browser-based desktop on your own hardware. It is based on Alpine Linux, targets x86_64, and is licensed GPL-3.0-or-later. File Station handles uploads and downloads, previews for common media and document formats, ZIP operations, recycle-bin restoration, and expiring password-protected public links. Storage tools show S.M.A.R.T. health, RAID status, and per-volume usage, and support disk initialization and configurable storage for virtual machines and containers. Container Manager handles Docker containers and images, logs, resource statistics, and docker-compose stacks. KVM/QEMU virtual machines support ISO booting, qcow2 disks, and an in-browser noVNC console. Package Center offers one-click self-hosted services such as Jellyfin, Nextcloud, Pi-hole, Vaultwarden, Gitea, Home Assistant, Portainer, and Immich. File sharing supports SMB/CIFS, NFS, and AFP, with Time Machine targets. The Free plan is free. The current installer is version 0.9.0-beta.1 for x86_64 and supports UEFI and BIOS boot; it requires compatible 64-bit x86_64 hardware, at least 2 GB RAM, and an 8 GB or larger USB stick.
