Changeling vs Metamorph

This page is created to help you decide whether Metamorph or Changeling is right for you.

Changeling is based on Metamorph. Like Metamorph, Changeling uses the same mod id ('metamorph') and thus has many of the same features and similar API. Add-ons made for Changeling will usually also work for Metamorph, and vice-versa, however compatibility is not guaranteed. Likewise, the config and save file formats will likely be similar, but not the same. Depending on your use case, one mod will provide a better experience than the other.
