// DOCUMENTATION
How OPEN//77 works.
The platform, the architecture, and the creator toolkit — documented in the open as the pre-alpha evolves. Design documents, not final specs.
// Overview
OPEN//77 is an open platform that brings community-run multiplayer servers to Cyberpunk 2077 — the way FiveM opened GTA V. Not one server: an ecosystem of them, each with its own game mode, rules and community.
OPEN//77 is not
- One official multiplayer server run by us
- A fixed game mode you have to play
- A peer-to-peer co-op session mod
- A product of CD Projekt RED
OPEN//77 is
- The infrastructure that lets anyone run a Cyberpunk 2077 server
- A client that discovers and connects you to community servers
- A creator toolkit for building custom game modes and systems
- Common ground for players, server owners and developers
// How it works (for players)
-
01
Own the game
OPEN//77 requires your own legal copy of Cyberpunk 2077. The platform never distributes game content — it builds on the game you already have.
-
02
Install the client
The OPEN//77 client runs alongside your installation. Your single-player game, saves and mods stay untouched.
-
03
Browse the servers
Open the server browser, filter by game mode or language, read a server's page, and pick the world you want to live in tonight.
-
04
Connect & play
The client fetches that server's resources automatically and drops you into Night City — alongside every other player on the same server.
// Dedicated servers
OPEN//77 is built around real dedicated servers, not peer-to-peer sessions. A server is a persistent process that a community operates — it holds the authoritative state of its world, and players connect to it.
-
Persistent worlds
The world keeps running when you log off. Economies, factions and stories continue — the server remembers.
-
Authoritative state
Positions, inventories, vehicles, money: the server decides what's true. That's what makes real economies and fair PvP possible.
-
Operated by communities
Anyone will be able to run the server software — on their own hardware or a rented machine — and set their world's rules, mods and moderation.
// Resources & scripting
A server is only as interesting as what runs on it. Resources are packages of server and client logic that add systems to a world — from a taxi job to an entire roleplay framework:
- Game modes — races, heists, survival rules, team PvP, story co-op
- Player systems — jobs, factions, reputation, character identity
- Economy — currencies, shops, property, player-run markets
- World interactions — vehicles, doors, props, districts, events
- Custom UI — HUDs, menus, phones, tablets rendered in-game
The scripting API sketched here is a design preview — the surface will evolve with the pre-alpha.
// Roadmap
OPEN//77 is in pre-alpha. There is no public build, no live server list, and no release date — and we won't invent any. Here is the honest shape of the road.
-
NOW PRE-ALPHA
Core multiplayer foundations
Client/server architecture, session handling, and synchronizing players inside the same world — the unglamorous groundwork everything else depends on.
-
NEXT
Dedicated server & resource system
The self-hostable server build, the resource format, and automatic resource delivery to connecting clients.
-
THEN
Server browser & creator SDK
Public server discovery, server pages, and a documented scripting API so the first community worlds can open their doors.
-
BEYOND
The ecosystem
Featured communities, server reputation, resource sharing between servers — the parts that only matter once real worlds exist. The community will shape these.
// FAQ
Is OPEN//77 official? Is CD Projekt RED involved?
No. OPEN//77 is an independent community project. It is not affiliated with, endorsed by, or supported by CD Projekt RED. Cyberpunk 2077 is the property of CD PROJEKT S.A. — we build alongside the game, not on their behalf.
Do I need to own Cyberpunk 2077?
Yes, always. OPEN//77 never distributes the game or its assets. You need your own legal copy of Cyberpunk 2077 on PC; the platform adds multiplayer infrastructure on top of it.
So is this one big multiplayer server?
No — and this is the core idea. OPEN//77 is the platform underneath many servers. Communities run their own independent worlds with their own game modes and rules; the client lets you browse and join them. If FiveM's model for GTA V is familiar, that's the shape.
Can I play it right now?
Not yet. The project is in pre-alpha and there is no public build. We publish development progress openly rather than promising dates — when a build is ready for testing, it will be announced through the project's channels.
Will I be able to host my own server?
That's the whole design. The dedicated server software will be self-hostable, so you can run your world on your own hardware or a rented machine, moderate it your way, and list it in the public browser. See Create a Server.
What can server creators actually customize?
Servers run resources — packages of server-side and client-side scripts. That covers game modes, jobs, economies, missions, vehicle handling, custom UI and world interactions. A pure racing server and a hardcore roleplay city can both be OPEN//77 servers.
Will it break my single-player game or saves?
The client is designed to run alongside your installation without touching your single-player saves or mod setup. Multiplayer state lives on the server you join.
How much will it cost?
OPEN//77 is a community project, not a storefront. The platform itself is intended to be free to play on. Beyond that, honest answer: sustainability decisions come after a working platform, and they'll be discussed in the open.
