xegen: full, server-ready game worlds in about a minute

June 2026

A map seed is a promise: type these numbers, cross your fingers, find out what you got after the server boots. xegen is the opposite. It generates the whole world - terrain, biomes, points of interest, trader placement - renders it so you can see exactly what you're getting, and hands you a file you drop straight into a dedicated server. About a minute, start to finish.

xegen 3D overhead render of a generated 7 Days to Die world - snow peaks, water inlets, trader markers across an 8,192-tile map — Overhead 3D preview of a generated 7 Days to Die world - an 8,192-tile landmass with snow peaks, water inlets and trader markers.

Seeds tell you nothing. xegen shows you everything.

Vanilla random generation gives you a seed and a wait. You can't tell a great map from a dud until you've already loaded it onto the server and walked it. xegen flips the order: it builds the full world up front and renders it three ways so you can judge it before you commit - then exports a clean, server-ready world folder.

What it produces

xegen top-down 2D map render with POIs, trader positions in red, biome boundaries and contour lines — Top-down 2D render with POIs, trader positions (red), biome boundaries and contour lines. A sample world: **4,086 POIs, 5 traders, 85.8 MB** - all visible before download.

xegen 3D terrain render showing elevation, biomes and town layout — 3D terrain - elevation, biome flow and town layout at a glance.

xegen close-up showing biome transitions and town-grid detail — Close-up - biome transitions and town-grid precision.

Because the preview quantifies the world - POI count, trader count, file size - you're choosing a map on evidence, not on a lucky seed. Don't like the trader spread or the biome split? Regenerate and look again. The whole loop is about a minute.

Which games

xegen powers the world generators on this site. Each one is free, runs in the browser, and exports a drop-in server world:

7 Days to Die world generator - the flagship: full RWG-style world with previews, POI & trader counts, and a server-ready download.
Terraria world generator - generate a world server-side without launching the client.
Vintage Story world generator - set up a world for your dedicated server.
Factorio map generator - dial in map-gen settings and export them.

How it works

Pick a game generator and set the basics (size, options).
xegen builds the world on a worker and renders the 3D + 2D previews - about a minute.
Eyeball the previews and the numbers. Regenerate until you're happy.
Download the server-ready world and drop it into your dedicated server.

No client install, no accounts, nothing to clean up afterwards. If you'd rather skip the server setup entirely, Supercraft hosts these games with the world already loaded - online 24/7, auto-updates, daily backups.
