## What it is
Mainsail is a responsive web interface for managing and controlling 3D printers running Klipper firmware via Moonraker. It provides a dashboard with live print monitoring, G-code and bed mesh viewers, macro management, file management, and multi-printer farm support.

## Use cases
- control my klipper 3d printer from a browser
- monitor print progress and temperatures remotely
- manage multiple 3d printers from one dashboard
- view and edit gcode files on my printer
- calibrate bed mesh with a 3d heightmap visualization
- run and organize klipper macros
- set up webcam monitoring and timelapses for prints
- send print jobs from my slicer to the printer

## When to choose
- you run Klipper firmware with Moonraker and want a polished web UI
- you manage a printer farm with multiple Klipper printers
- you want built-in G-code viewer, bed mesh visualization, and timelapse support
- you need a responsive interface that works on desktop, tablet, and mobile

## When to avoid
- your printer runs Marlin or other non-Klipper firmware
- you prefer a terminal-only or minimal headless control setup
- you need a slicer or CAM tool rather than a printer control interface

## Facets
