Welcome to Mainsail

A modern and responsive user interface for Klipper. Control and monitor your printer from everywhere, from any device.

Easy to use. The focus lies on both anticipating what users may need to do and ensuring that the user interface contains elements that are easily accessible, understandable, and user-friendly to make those actions easier.

Always one step ahead. We work closely with developers of other projects so that functions can already be implemented early on.

100% open source. Anyone can join, anyone can contribute.
