## What it is
Biomes is an open-source sandbox MMORPG that runs entirely in the web browser, built with Next.js, TypeScript, React, and WebAssembly. It features a distributed server architecture that can also be run locally, letting players build, forage, and play minigames together.

## Use cases
- play a browser-based sandbox MMO
- self-host a multiplayer voxel game server
- study how to build an MMORPG with web technologies
- contribute to an open-source game engine in TypeScript
- build minigames inside a shared online world
- learn reactive gameplay programming with React

## When to choose
- you want a fully open-source, browser-playable sandbox MMO
- you want to self-host and modify a multiplayer game server locally
- you want to learn large-scale TypeScript/React/WASM game architecture

## When to avoid
- you need a native desktop or mobile game client
- you want a polished, production-supported commercial game
- you need high-performance 3D graphics beyond what web technologies provide
