FiveM

FiveM is a modification for Grand Theft Auto V enabling you to play multiplayer on customized dedicated servers, powered by Cfx.re.

Building upon years of development on the Cfx.re framework, which has existed in various forms since 2014, FiveM is the original community-driven and source-available GTA V multiplayer modification project. FiveM allows servers to keep the original game AI, so you'll never be alone. You can also PvE. FiveM allows servers to use custom cars, maps, weapons, and more dynamically. FiveM uses Rockstar's network code with improvements, so you'll have the best sync around. FiveM doesn't modify your GTA V installation, so you can switch between GTA:O and FiveM without getting banned.
