wget is your friend.
Type this in a unix shell account:
wget -Ekpmnv https://ubbdev.com
And you will have a complete working local copy of threadsdev. After a while, it'll take some time downloading everything. =]
If you are on windows, you could use something like cygwin to use the wget program. Don't ask me how cygwin works though, because I don't know that.
There is a windows gui available on this site:
