FiveM is a modification for Grand Theft Auto V enabling users 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. We strive to put the community ― both players, server owners, and the greater GTA mod community ― first. FiveM allows servers to use custom cars, maps, weapons, and more dynamically. It doesn't modify your GTA V installation, so you can switch between GTA:O and FiveM without getting banned.
Also,allows servers to keep the original game AI, so you'll never be alone. You can also PvE!
