Lightyear is a Rust networking library for building server-authoritative multiplayer games with the Bevy game engine. It provides transport-agnostic connections (UDP, WebSocket, WebTransport, Steam), message channels, input handling, and entity replication with prediction and interpolation.

Use cases

• build a multiplayer game in Bevy
• add server-authoritative networking to a Rust game
• sync game state between clients and server
• implement client prediction and rollback for an FPS
• run a Bevy multiplayer game in the browser via WebTransport
• send reliable and unreliable messages between game clients

When to choose

• you are building a multiplayer game with Bevy
• you need server-authoritative state replication with prediction and interpolation
• you want transport flexibility including WebAssembly/WebTransport support

When to avoid

• you use a game engine other than Bevy
• you need peer-to-peer networking rather than client-server
• your project is not written in Rust
