FiveM is a modification framework providing many tools to personalize your server's gameplay experience.
Using our advanced features, you can make whatever you wish: roleplay, drifting, racing, deathmatch, or something entirely unique?
Your skills are the limit!
Server system requirements: x86-64 system capable of running Mono/.NET (Linux ~2014+, Windows 7/2008+), decent upstream connection.

Nope! FiveM does not interact with the Rockstar Online Services other than to validate your game copy the first time you launch it. This validation emulates the game's interaction, and can not be detected by Rockstar.
It also doesn't modify your game files at all, even when downloading server assets, so you don't have to do anything to move between FiveM or GTA:O.
We need to do this to check if you actually own GTA V, when our automatic validation fails. This data will only be sent to the Rockstar Social Club services, and is not transmitted to us, or any other party.
We currently only support 24 slots due to a bug in handling the RAGE network framework, 32 slots will be released as soon as the server transport layer gets replaced with ENet. We're also working on a completely new synchronization framework called OneSync, which should allow higher slot counts — we are targeting 64 initially, but it should be easy to exceed — which should be coming Q4 2017 (between October and December).
No, all your existing scripts will still work with the game when OneSync is released. Of course, OneSync will enable new, better ways of doing certain things you do in your scripts, so you might want to take advantage of those when they're released.
FiveM is the original project both FiveReborn and MultiFive were based on. The current FiveM project originated from a merger between FiveReborn and a new development group called the CitizenFX Collective.
Modifications, not multiplayer. FiveM also allows you to modify the singleplayer experience, or well, it will in the future.
There's probably an installation guide on the wiki telling you how to do so. If not, check the forums!
