# What is Patcher

Patcher is a digital twin workspace for Eurorack musicians.

The public side is a browseable catalogue of modules with the racks and patches other people have built around them. The signed-in side is your own workspace — the modules you actually own, the racks you are planning, the patches you are capturing, and the manuals gathered around them.

You can move between the two freely: browse publicly, sign in when you want to save your own work, and share back only what you choose to make public.
