evolve™ itself is not; however it is built around several key open source technologies which we use to deliver the system including Apache, MySQL, Python, Open SSL and of course Gentoo® Linux.

We are strong supporters of the open source principal too and have chosen to open source several of our own internal systems which have been given over to the community as part of a desire to make a fair contribution back. Our current open sorce projects include Flow- a comprehensive front end admin system for the Exim IMAP mail server; and contributions to the M2Crypto Python-OpenSSL and apache web server libraries.
