## What it is
Moonraker is a Python-based web API server that exposes HTTP and WebSocket APIs for controlling and monitoring the Klipper 3D printer firmware. It communicates with the Klippy host over a Unix domain socket and serves as the backend for clients like Mainsail and Fluidd.

## Use cases
- control a 3d printer from a web interface
- expose klipper firmware over a rest api
- monitor 3d printer status remotely
- build a custom frontend for klipper
- manage printer updates and power devices over the network
- run klipper with mainsail or fluidd

## When to choose
- you run Klipper and want a web UI such as Mainsail or Fluidd
- you need programmatic HTTP/WebSocket access to printer state and commands
- you want remote monitoring and management of a 3D printer on a Raspberry Pi

## When to avoid
- you use Marlin or another non-Klipper firmware
- you need a bundled UI - Moonraker is a server only and requires a separate client
- you want a standalone print server unrelated to Klipper

## Facets
- artifact type: service
