FiveM is a PC multiplayer framework for Grand Theft Auto V. It lets communities run their own servers with custom vehicles, maps, scripts and rules, separately from Rockstar's standard GTA Online sessions.14
What can you play?
Roleplay is FiveM's best-known use: players create characters and take jobs or other roles in a shared city. Servers can also focus on racing, combat, free roam or entirely custom game modes. FiveM supplies the framework; each community decides what its server contains and how players can join. NoPixel is one roleplay community; its access rules do not apply to every FiveM server. FiveM and roleplay guide explains the different server types and the steps to join one.
OneSync is FiveM's network synchronization system. The advertised OneSync capacity is up to 2,048 players on a server, with an Element Club Platinum subscription required for that maximum. This is a capacity ceiling, not the player allowance or expected population of every server.5
GTA V Legacy and Enhanced
FiveM Legacy works with the PC Legacy edition of GTA V. A separate FiveM client for GTA V Enhanced entered early access in July 2026; it runs alongside Legacy rather than replacing it. The official FiveM website offers the appropriate client and lists the requirements for each edition.4 The Enhanced early-access report explains what changed at launch. FiveM is a PC service, not a console version of GTA Online.4
For server owners moving custom content between editions, Cfx.re's Alchemist tool converts supported Legacy 3D assets to Enhanced formats and can refine older Legacy assets to correct formatting problems. It copies surrounding scripts, interfaces and configuration files unchanged, rather than rewriting them. The Alchemist documentation explains the conversion steps and supported formats.6
Who develops FiveM?
The Cfx.re team develops FiveM and the related RedM platform for Red Dead Redemption 2. Cfx.re joined Rockstar Games in August 2023.2 That does not make every community server a Rockstar-operated game: server owners still set their own experiences and rules.
Finding a server
After installing the client, players can browse servers by interest rather than treating FiveM as one single world. The server explorer lists FiveM and RedM communities, while the getting-started guide walks through installation and joining. NoPixel V is a separately named roleplay project whose invitation-only beta uses the Rockstar Games Launcher; its access arrangements do not define FiveM as a whole.3
