Not to be confused with the 2014 OpenBlox (legacy version) repo that has been found
Clues:
The outdated repo: https://sourceforge.net/projects/openblox/
The comment that stated where the repo is hosted ~3 years ago at the time of posting: https://farside.link/redlib/r/opensourcegames/comments/sujs4u/comment/hyjfgtg (Linked git site shut down at the time of this post)
Farside redirecting to RedLib doesn’t help much, a lot of them need to be updated or else get .json error that was already fixed. Original reddit link: https://old.reddit.com/r/opensourcegames/comments/sujs4u/roblox_clone/hyjfgtg/
