Lance is a Node.js-based real-time multiplayer game server with a companion client-side library that synchronizes game state between server and clients. It handles netcode concerns like binary serialization, lag compensation via interpolation/extrapolation, input coordination, and network spike handling so developers can focus on game logic.

Use cases

• build a real-time multiplayer browser game without writing netcode
• synchronize game state between a Node.js server and browser clients
• add client-side prediction and interpolation to a multiplayer game
• network a physics-based game using Cannon.js or pseudo-physics
• create a multiplayer arcade, RTS, FPS, or platform fighter in JavaScript
• minimize bandwidth with binary serialization over websockets

When to choose

• you are building a real-time multiplayer game in JavaScript/TypeScript for browsers
• you want lag handling, prediction, and interpolation handled for you
• you want a game-agnostic server that supports many genres
• you prefer a configurable, debuggable netcode framework over building from scratch

When to avoid

• you need UDP or WebRTC transport (still on the roadmap)
• you are building a turn-based or non-real-time game
• you need a full game engine with rendering built in
• you need a project with very active recent development
