There are a couple reasons why bgtoolset is not open source, available separately, or on GitHub. The main reason is that the creator wants to keep it private for now, and the other reason is there is no non-ssl version of the toolset currently, or one that can run via local swf.
The other tools including HEN, HAN, and all related projects are provided as open source and available on GitHub at https//GitHub.com/PS3Xploit
The bgtoolset will be redeployed using its own domain, but will also be linked via main .me domain, as before.
