## What it is
A standalone, distributed game server for Screeps, an MMO RTS sandbox game where players program their units' AI in JavaScript. It lets you host your own persistent game world locally or on a dedicated server, connectable via the Steam game client.

## Use cases
- host a private Screeps game world on my own server
- run a local Screeps server for testing my bot AI
- set up an automated testing framework for Screeps scripts
- self-host a persistent MMO world for a community
- distribute Screeps server processes across multiple machines

## When to choose
- you want to run your own Screeps world instead of the official servers
- you need a controlled environment to test and benchmark your Screeps AI code
- you want to customize server configuration or swap the storage backend

## When to avoid
- you just want to play Screeps on official servers without hosting
- you need a game server for a different game or engine
- you cannot run Node.js 22+ and build tools on your host
