Hello I was just wondering how exactly do you create a santosrp server on gmod, Does it cost to keep it running, do you install a specific gamemode. I would like to know how do you create a santosrp server.

You will need the gamemode, however, it is private. There is a leak being sold around, but it is incomplete and doesn’t work out of the box.

but if it is private how come are their many other santosrp servers

They either obtain a complete copy from the owner or fix up the leak. I don’t know which is the majority case.
