Terraria World Workshop
Build Your Own World

Start with a world you know, then carve it, fill it and grow it into somewhere nobody has seen before. You will edit real Terraria worlds in the free TEdit editor, then save and share a world of your own.

Two ways to learn this: the full series needs the paid Terraria game plus free mod tools (tModLoader and TEdit), so it is a home-computer job best with a grown-up. But you can start right now, with no install, in the browser studio, on any computer including a school one.

Ember says: we build in small steps, and each one ends with something you can actually see in the world. No giant leaps. By the last episode you will have your own world that you can load, save and share.
🛠️ Open the Terraria World Studio A browser playground for this series: paint and dig tiles, build a biome, add chests, walk and dig to test, plan your world files, debug a tModLoader log and download your world plan. No install, works on a school computer. Start building →
⏱️ Your first 15 minutes (no install)
  1. Open the World Studio.
  2. Paint some dirt, stone, grass and a pond on the map, then add a house.
  3. Press Start walk test and try to walk into the stone. It should block you.
  4. On the Download your world tab, download your world plan. That is a real plan you can build from.

Then, when you have the game and a grown-up to help with the install, start Episode 1 and take it into Terraria for real.

Try it now: Sketch your world

Plan a layout in your browser before you open TEdit. Pick a tile, click or drag on the grid to paint, then download your plan. This bit needs no install and no game, so you can start right now.

Tip: paint the ground first, then stone, then trees and chests on top. "Save plan" gives you a file you can open again or build from in Episode 3.
