Overview

AI-generated overview

Read-only Warhammer 40,000 reference: datasheets, points, detachments, missions and core rules.

What it does
Connects an assistant to Praetorium's public Warhammer 40,000 reference, which serves faction datasheets, missions, detachments, points and core rules from verified community data snapshots. The README states the public reference is available without an account and that each page reads the service's verified community data snapshot. The manifest lists no tools, so the exact tool set is not documented here.
When to use it
Useful when you want an assistant to look up Warhammer 40,000 rules, unit datasheets, points or missions while list-building or discussing a game. It is a reference lookup only; the README says Praetorium does not provide matchmaking, chat, tournament pairings, or a rules encyclopedia.
Requirements
A remote streamable HTTP endpoint at praetorium.gg; no packages, environment variables or headers are declared. No account is needed for the public reference, though the README notes an account is required to play or keep a list.
Before you install
Read-only reference data; the manifest declares no authentication, credentials or secrets. The README notes the repository contains no game data and that the service uses verified snapshots from configured community sources, so catalogue and rules content comes from third parties (BSData, 40kdc-data). Warhammer 40,000 marks belong to Games Workshop and Praetorium is unofficial.

Product

Praetorium is a free, open source Warhammer 40,000 army builder and battle tracker. Build and share lists, browse the community catalogue, and compare units in the combat simulator. Play 1v1, 2v1, or 2v2 games with friends, or run a practice game. Track setup, turns, scoring, and casualties.

Anyone can watch public battles and see the leaderboard. Players can control who sees their battles and run league events with sealed rosters.

Scope

Praetorium does not provide matchmaking, chat, tournament pairings, or a rules encyclopedia. An account is required to play or to keep a list, though not to watch a public battle, read the leaderboard, or try the roster builder.

This repository contains no game data. The service uses verified snapshots from the configured community sources.

Use

praetorium.gg is the supported service and the easiest way to use Praetorium. It keeps the community rules data current and saves your rosters and battles.

The public reference is available without an account: faction datasheets, missions, and rules. Each page reads the service's verified community data snapshot.

The source is open so anyone can inspect the product and contribute to it. Contributing covers running a local development copy.

Development

See Contributing to run the app and its checks, Architecture for code placement, and AGENTS.md for coding-agent rules.
