Why is Amahi not a popular home server solution?

With Nextcloud enterprises host their own secure cloud solution for storage, collaboration & communication from any device, anywhere.

Rockstor is a free and open source NAS (Network Attached Storage) operating system.

Rockstor is another one that rarely gets talked about. I never used it, but it looks interesting and might be good if someone wants a WebUI for managing btrfs.

OpenMediaVault is the next generation network attached storage (NAS) solution based on Debian Linux.

Anyway, I also use ZFS. My server distro of choice is OpenMediaVault, which has a great ZFS plugin that allows easy management via Web UI.
