Setup in 4 Steps

Skip the manual SteamCMD installation, port forwarding, and systemd configuration. Install on your own computer and start hosting instantly.

Step 01

Create a GameCP Account

GameCP gives you a full control panel with Docker containerization, file management, automatic port forwarding, and automatic updates — all built in.

Step 02

Connect Your Hardware

Install GameCP on your own desktop, laptop, VPS, or dedicated machine. One-line install — no SSH expertise needed.

GameCP installs Docker, configures networking, and sets up automatic port forwarding so your friends can connect instantly. Start hosting from your own PC and scale to a VPS later. Supports Windows, macOS, and Linux.

Step 03

Deploy Arma Reforger

Select "Arma Reforger" from the template library and hit deploy. GameCP handles SteamCMD (App ID: 1874900), ports, startup commands, and all configuration automatically.

Includes pre-configured config.json. Uses the steamcmd:debian image. ~5 GB storage.

Step 04

Start Playing

Hit start and share your server address. Automatic port forwarding handles the rest — no router config needed.

GameCP monitors your server health and provides live logs from your browser. Your friends connect using the address GameCP gives you.
