Discord's own templates only spin up a brand new server. mimBo's is different: you can copy a whole layout onto a Discord server you already run, without losing the channels, roles and history that are already there.
A native Discord template can only create a fresh server. If your community already exists, that is no help at all: you cannot clone a Discord server onto itself, and rebuilding by hand is tedious.
mimBo's applies a template to an existing server additively. It reads what your server already has and fills in only what is missing, so you can copy a Discord server layout onto a live community in a couple of clicks.
Want a layout of your own to copy across servers? Design it in the visual builder at mimbos.com/builder, then apply it to as many existing servers as you like. See how to make a Discord server template.
