What is the Old World Builder?
Updated on November 11th, 2026, by Rob Baer with a tighter overview of the app. Originally published in September 2024.
Army builders are one of the best tools a game can have, and this one is about as painless as it gets. The Old World Builder is a free browser-based app for Warhammer The Old World that lets you crank out lists without fuss.
Oldworldbuilder.com is mobile-friendly and can live on your home screen like a proper app. Once the dev finishes loading all the army data, they are aiming to spin it out as a full Android release too.
You can create, edit, duplicate, delete, export, and print both units and full lists. There are seventeen armies in the mix right now, from Orcs and Goblins to Tomb Kings, Empire, Dwarfs, and Bretonnia. Every time a new book lands, it gets added, so the tool keeps growing right along with the game.
Features and Supported Armies
Every Army Book for Warhammer: The Old World and Warhammer Fantasy 8th Edition is already in the builder, and it all works offline, so a dead signal at the store won’t stop you from tweaking a list before your game.
The Background of Old World Builder
The dev behind this project has been grinding Warhammer Fantasy since back in the day, so after wrestling with BattleScribe and spreadsheets, they built Old World Builder themselves.
