Simple server management for Linux

Unlock the power of Linux with Symbiosis

Setting up a server from scratch can be fiddly and repetitive. That's why we created Symbiosis: a simple but powerful way of setting up and managing servers, based on the reliability of Linux.

Using Symbiosis to manage your server means there is less time spent setting it up and more time spent developing your applications.

Symbiosis is built on reliable Debian GNU/Linux. It's available free with every Bytemark server and is fully documented.
