GTA Roleplay itself is free, but you need to own a copy of GTA V to play it. You will also need to install the FiveM mod, which is free to download and use. However, some servers may have a Patreon or similar donation system in place, where players can contribute financially to support the server and may receive perks or priority access in return. It is important to note that each server is different, and it is best to check the server's rules and guidelines for more information on their donation system and perks.
