What is Manabrew ?

Manabrew is an open-source Magic: The Gathering client and rules engine. It focuses on a modern gameplay experience, with a multiplayer first mindset. Currently supports most formats, including commander up to 4 players. Manabrew’s engine, whilst experimental, was ported in rust from forge so it can run anywhere — including directly in your browser via WebAssembly.

Play in the browser

The full client runs as a static site at manabrew.app — no install required.

Desktop App

Cross platform application for macOS and Windows (experimental)

Swappable engine

Play with multiple engines developed by the community. We currently support Manabrew’s official engine, as well as forge

Multiplayer

Play with friends in multiplayer lobbies, up to 4 players.

Note

Manabrew is unofficial fan software. It is not affiliated with, endorsed by, or sponsored by Wizards of the Coast LLC or by the Forge project. Card images are not shipped by this project.

Project status

Manabrew is pre-release software, and its game engine is swappable. Two backends drive the same client today:

• Manabrew engine — the Forge port that runs everywhere, including in your browser. It plays a growing set of matchups, with card coverage expanding through parity testing against Forge.
• Forge engine — fully supported as a first-class way to play. Rooms hosted on a self-hosted node run games on the original, battle-tested Forge rules engine with its complete card coverage.

Next steps
