## What it is
Valence is a Rust framework for building custom Minecraft: Java Edition servers from scratch, built on Bevy ECS. It acts as a game engine for Minecraft servers, letting developers write their own game logic and optional plugins for highly custom experiences like minigame servers.

## Use cases
- build a custom Minecraft server in Rust
- create minigame servers with custom game logic
- implement Minecraft protocol handling from scratch
- run high-player-count Minecraft servers efficiently
- extend Minecraft server behavior with ECS plugins

## When to choose
- you want full control over Minecraft server logic in Rust
- you need a modular, plugin-based Minecraft server framework
- you need to support thousands of concurrent players with low memory use

## When to avoid
- you need a drop-in vanilla Minecraft server with complete game mechanics
- you need multi-version Minecraft client support out of the box
- you need a stable, production-ready server with no breaking changes

## Facets
- artifact type: framework
- maturity: experimental
- function: game-engine, plugin-system, networking, serialization, auth, concurrency
- domain: gaming-tools
- platform: rust, windows, cross-platform
- tags: minecraft-server, bevy-ecs, minecraft-protocol, minigames, nbt, game-development, minecraft, linux, macos
