boardgame.io is an open-source JavaScript/TypeScript engine for building turn-based games. Developers write simple move functions and the framework handles state management, realtime multiplayer networking, storage, AI bots, and game phases without manual networking code.

Use cases

• build an online multiplayer board game
• create a turn-based card game with React
• add AI bots to a tabletop game prototype
• sync game state between players in realtime
• implement game phases with different turn orders
• prototype game moves before rendering a UI
• build a chess or checkers web app with matchmaking lobby

When to choose

• you are building a turn-based game (board, card, tabletop) in JavaScript or TypeScript
• you want multiplayer networking and state sync without writing server code
• you use React or React Native and want view-layer-agnostic game logic
• you need auto-generated AI opponents or game logs with time travel

When to avoid

• you need real-time action or physics-based gameplay rather than turn-based logic
• you are building a game outside the web/JS ecosystem
• you need a full-featured general-purpose game engine with rendering, audio, and asset pipelines
