Pterodactyl is the modern answer to a game server control panel that makes everything easy for the user. We use Pterodactyl for our Garry's Mod and Minecraft servers. Control all of your servers from one unified interface.
You can see a live version of the server console on the dashboard. Run commands as console and overlook in-game events & commands live.
You can modify server startup parameters through the config page. It have never been easier to manage your server.
