Because openpilot is an opensource software, anyone is able to go on the openpilot GitHub and make their own fork/branch. Basically, they are able to copy all the code for openpilot, modify it, add their own features, etc.
That is what the other branches are.

The communities for the big three branches (Sunny, Frog, Dragon) are huge and very well supported. People can request tweaks, develop and support themselves and just talk about the software in their perspective Discords. (Dragon has a facebook page).

These branches are safe. There are some unsafe branches but my site will not have any of those listed.
