Cyberpunk 2077 Multiplayer Server Hosting UK

What Is OPEN//77 Server Hosting?

OPEN//77 server hosting is a managed service that runs an OPEN//77 dedicated server on professional hardware in a datacentre, around the clock, so your community's world, its resources and its rules are online whenever players want to join. Every GTX Gaming OPEN//77 server comes with NVMe storage, daily automatic backups, enterprise DDoS protection, a web control panel and a 24/7 support team.

People look for it as a Cyberpunk 2077 multiplayer server, a Cyberpunk 2077 dedicated server, a Night City roleplay server or a way to play Cyberpunk 2077 online with friends. With OPEN//77 they all mean the same thing: your own always-on OPEN//77 server, with your community and your game mode.

What Is OPEN//77?

OPEN//77 (also written Open//2077) is a community-run multiplayer platform for Cyberpunk 2077. It is not one official server but three parts: a launcher that signs players in, checks their game and opens a server browser; a dedicated server that communities run themselves; and a Lua scripting layer for building game modes. Every community operates its own server, game mode and rules, so one server can be a strict roleplay city with its own economy and staff while the next is a racing league, a PvP arena or freeroam.

• Status: Open Alpha, open to everyone with no application or approval. The project says to expect bugs and changes to its features and APIs.
• Dedicated servers: the server holds the authoritative world (positions, inventories, vehicles, loot, time and weather), and the world keeps running when players log off.
• Server browser: public servers register with the OPEN//77 master server and appear in the launcher; private ones stay off the list.

An Unofficial Fan Project

OPEN//77 is an unofficial, independent community project. It is not affiliated with, endorsed by or sponsored by CD PROJEKT S.A. "Cyberpunk", "Cyberpunk 2077" and related marks are trademarks of CD PROJEKT S.A. GTX Gaming is not affiliated with CD PROJEKT S.A. or with the OPEN//77 team: we host the OPEN//77 dedicated server software that the project publishes for everyone.

That matters for what you can expect: OPEN//77 does not come from the makers of Cyberpunk 2077, and features, requirements and compatibility can change while it is in Open Alpha. Everything this page says about OPEN//77 comes from the project's own website and docs as the project's docs describe them in November 2026.

What Players Need to Join

Hosting changes nothing on the player side. Every player who joins your server needs their own legal copy of Cyberpunk 2077 at game build 2.5 with the Phantom Liberty DLC, a Windows 10 or 11 64-bit PC, the free OPEN//77 launcher and a free OPEN//77 account.

• Game build 2.5 exactly: the OPEN//77 client is built against that build and refuses to load when it does not match; the launcher checks it before it installs anything.
• Phantom Liberty is required: the world players land in when they connect is a Phantom Liberty save.
• Own copies only: OPEN//77 never distributes the game or its assets, and pirated or cracked copies are not supported.

Players download the launcher from the OPEN//77 download page; their own single-player game, saves and mods stay untouched.

Your OPEN//77 Licence Key

Every OPEN//77 server needs a licence key from its owner: no key, no listing. You register a free account on open2077.net, verify your email and mint a key in your account. The key starts with op77_live_, is shown only once (the platform keeps only a fingerprint), one account can hold up to twenty active keys, and one key can enrol more than one server. Revoking a key cuts off every server enrolled with it at once.

The OPEN//77 licensing docs say the key goes in the OP77_LICENSE_KEY environment variable, which they recommend, or in the masterServer section of server.jsonc. Treat it like a password: anyone holding it can enrol a server against your account. GTX Gaming does not create or sell OPEN//77 licence keys; you mint yours, you can revoke it, and if you are unsure where to enter it on your GTX server, our 24/7 team shows you.

Getting Started With Your Server

Our OPEN//77 servers are being set up now: ordering opens soon, and the price appears on this page when it does. When it does: pick a memory size and a location close to your players, add your own OPEN//77 licence key, set your server's name and visibility, and it can register with the OPEN//77 master server so players find it in the launcher. Until then, our 24/7 team answers your questions by live chat or ticket.

Resources, Lua 5.4 & the Workshop

Gameplay on an OPEN//77 server is not configured, it is scripted. A resource is a self-contained package with a manifest, Lua 5.4 scripts, declared permissions and optional web interfaces; the server loads it, and every player who connects downloads it, has its signature and content hashes checked and runs it before entering the world. Client scripts run inside the game, server scripts own the authoritative world, each resource gets its own Lua VM, and hot reload puts a saved change live without a restart.

Resources drive real game systems such as vehicles, blips, NPCs, weather, loot and interactions, and a resource can ship a Chromium WebUI page built in HTML, CSS and JavaScript for HUDs and menus. The OPEN//77 Workshop shares community-made resources, game modes, maps and tools, free to download, and the docs include a FiveM compatibility guide for people coming from FiveM.

Warden, the OPEN//77 Admin Panel

OPEN//77's own web admin panel, Warden, ships with the dedicated server and is off until you enable it. It offers a live console, hot reload of Lua resources, player moderation (warn, kick, ban), announcements, configuration and identity editing, Workshop installs and staff roles. The docs warn that Warden is complete control of your server and recommend keeping its address private (on localhost, a VPN or an SSH tunnel) rather than open to the internet, so ask our 24/7 team before you switch it on. The docs also cover RCON and Prometheus metrics.

Open Alpha Updates & Backups

OPEN//77 moves fast: its devblog has posted development updates almost daily in autumn 2026. The project publishes a stable server channel, recommended for live servers, and an unstable channel for testing that may break resources or compatibility. Players must run a client that matches the server build, and the docs say to back up configuration, resources and data before every update and to download the server only from the official OPEN//77 page or CDN. Daily automatic backups on every GTX Gaming server keep earlier copies of your server, so a bad update is never the end of your world.

How Much Does OPEN//77 Server Hosting Cost in the UK?

Our OPEN//77 servers are being set up now: ordering opens soon, and the price appears on this page when it does. Every server will include 10GB of RAM, NVMe storage, DDoS protection, daily automatic backups and 24/7 support, with no setup fee and no contract, and more memory can be added on the order form.

How Much RAM Does an OPEN//77 Server Need?

Every OPEN//77 server at GTX Gaming includes 10GB of RAM, and you can add more on the order form, up to 64GB. The OPEN//77 project has not published memory or CPU requirements for its dedicated server, and it does not publish a fixed player limit either: its docs list a maximum-players setting that you choose. Start with the included memory, watch the live memory graph in your control panel as you add resources and players, and add memory when your world needs it.
