Choose your workbench
Want the full toolbox? Download the desktop app for Windows, Linux, Steam Deck or macOS. It finds your worlds, shows your base in 3D with the game's own models, moves items between saves, works with Game Pass saves, and can edit a running game. Take the desktop tour.
Want to try it now? Open the browser editor. Choose your save folder or a zip copy of it. There is nothing to install. Follow the browser walkthrough.

Save, then head back in
Changes to a save wait until you press SAVE. When the editor writes a file, it keeps the old version beside it with .bak at the end of its name. Keep your own copy of a world you care about too.
Using a zip in the browser? Press SAVE, then EXPORT to download your edited world before closing the page. The browser guide explains how to put it back.
Live editing works differently. It changes the running game straight away and makes no editor backup. Start with the live editing guide before connecting.
