Arma 3 Web Server

Web-based management panel for Arma 3 dedicated servers. Start, stop, configure, and monitor your server from a browser.

Features

• Server control — Start, stop, restart, and view status
• Live console — WebSocket terminal showing server stdout/stderr and RPT log tailing
• Config management — Create, edit, duplicate, and delete .cfg configuration files with a Monaco editor
• Modlist management — Create modlists with reorderable entries, enable/disable per mod, import from HTML (e.g. ArmA 3 Steam Workshop collections), check download status
• SteamCMD integration — Update the server binary, download individual workshop mods, bulk download missing or outdated mods, all streamed live to the UI
• Settings UI — Edit server parameters, IP:port, platform, Steam branch/user, CBA/AI/difficulty presets, and select active config/modlist
• Log viewer — Browse and read server log files
