## What it is
A minimalist Minecraft server written in C, designed to run on memory-restricted embedded systems like the ESP32. It prioritizes memory usage and performance over full vanilla Minecraft feature compliance.

## Use cases
- host a minecraft server on an esp32
- run a minecraft server with very low memory
- self-host a lightweight minecraft server
- host minecraft on a microcontroller
- run a minimal minecraft server on a router or weak device

## When to choose
- you need to host Minecraft on extremely memory-constrained hardware like ESP32
- you want a tiny, fast server and don't need full vanilla parity
- you only need vanilla client support for recent protocol versions

## When to avoid
- you need full vanilla Minecraft feature compliance or plugin/mod support
- you use Fabric or other non-vanilla clients
- you want configurable settings without recompiling from source

## Facets
- artifact type: application
- maturity: active
- function: game, networking, http-server
- domain: gaming-tools, embedded-systems, self-hosted
- platform: windows, embedded, cross-platform
- tags: minecraft-server, esp32, embedded, cosmopolitan, minimalist, linux, macos
