What is a SandboxCode in 7 Days to Die?

Starting in V3.0 Dead Hot Summer, 7 Days to Die packs every sandbox difficulty setting into one compact string called the SandboxCode. Instead of editing dozens of separate properties in serverconfig.xml, you set a single SandboxCode value. This tool builds that string for you.

Where do I paste the SandboxCode?

In your server's serverconfig.xml, find or add the SandboxCode line and set its value to your code. Save the file and restart the server. The Copy button next to the serverconfig.xml line gives you the whole line ready to paste.

Where did GameDifficulty, XPMultiplier and BloodMoonFrequency go in V3.0?

V3.0 removed about 30 gameplay properties from serverconfig.xml and folded them into the SandboxCode. XP Multiplier and Block Damage are on the Player tab, blood moon settings on the World tab, loot abundance on the Resources tab. GameDifficulty was replaced by finer options like damage dealt, damage taken and Max Enemy Tier. The migration table on this page shows where every removed property went.

Can I get the code for a preset like Warrior, Insane or Undead Matinee?

Yes. Click any of the 17 built-in presets on this page: the 6 difficulty presets from Scavenger to Insane, plus the 11 official themed presets like Undead Matinee, Madmole's Mayhem and Bite Club. The preset's exact SandboxCode appears in the output box, ready to copy or fine-tune.

Why is my code so short, or just the letter A?

The code only stores settings you change from their default, which keeps it short. If every setting is on default, the code is just A, the version header. That is normal and valid.

Can I edit a code I already have?

Yes. Paste an existing SandboxCode, or a full property line copied from serverconfig.xml, into the Load an existing code box and press Load. The generator fills in every setting so you can adjust and copy again.

Is this tool safe, and does it send my settings anywhere?

Everything runs in your browser. Nothing is uploaded and no signup is needed. The settings, value options, and the code format all match 7 Days to Die V3.0.

Copy the generated code, or the full serverconfig.xml line.
3
Open your server's serverconfig.xml and set the SandboxCode property to your code.
4
Save, then start or restart the server. To tweak later, paste your code back in above and keep editing.
