How to use the generator
Start from a preset, set your name and gamemode, then adjust the Sandbox rules and limits. Both files on the right update as you go.
Put server.cfg in garrysmod/cfg/. Copy the startup options into your host’s startup settings, or add them to the end of your srcds command.
Your settings stay in this browser, and the link button shares them. Passwords and your Steam token are never saved or shared.
Only what you changed
Sandbox rules and limits left at the game’s default stay out of server.cfg, so the file is short and you can see at a glance what’s different on your server.
Where these facts come from
Startup options, the location flag and the server token come from Facepunch’s Garry’s Mod wiki. Every Sandbox limit and default comes from sandbox.txt, the Sandbox gamemode’s settings file in Facepunch’s own repository. Checked in November 2026.
This is a fan-made tool by Wilderack, not an official Garry’s Mod or Facepunch Studios tool.
