As of 2014 Erlang on Xen is open source. The open source license requires that all software used in conjunction with Erlang on Xen is open source too.
Our build service exposes the most recent development branch of our software and is free for any purposes, including commercial use.
Additional licensing options include:
– Annual support constracts. Such contracts ensure that features and bugs critical for the client receive preferential treatment.
– Private build service instances. A local copy of the build service may improve security of the client's projects that use Erlang on Xen.
Please inquire us via e-mail regarding particulars of the above options.
