Amahi is an open-source home server distribution based on Linux. It's flexible and customizable, with a ton of apps and plug-ins. It starts as a simple file server (a NAS), however, it can also pool a bunch of hard drives into a redundant storage pool. It has apps for backups, VPN, streaming and much more, with PHP, Python, node.js and server-based apps being popular web-apps packaged for Amahi. The core of the platform is based on Ruby on Rails, however our code base includes project written in Go, ruby, PHP, Python and some bits in perl.
