What is Symbiosis?

Symbiosis is an easy-to-use hosting environment developed by the team at Bytemark. The design goals were to invent a way of managing a server that was easy to use, but integrated well with Debian GNU/Linux.


We recognised the need to balance the need for ease of use with running cutting-edge websites, and reliable email handling. Symbiosis runs the following technologies:

  • Apache web server,
  • Exim 4 mail transport agent,
  • Dovecot IMAP and POP3 server,
  • MySQL database server,
  • PHP5 scripting language
  • SpamAssassin spam filtering, and ClamAV anti-virus,
  • Pure-FTPd FTP server,
  • SquirrelMail webmail program


A complete set of documentation is available, both in HTML and PDF formats


Symbiosis is open-source, and we have a development site for both the main project as well as the documentation
