rig2c is a software library enabling applications to use rigs generated by kp2rig. Most developers won't use this directly (but you certainly can), and will instead choose a higher-level API that wraps it, including:
- rig2cs, for Unity, Universal Windows Platform (UWP), custom C# application
- rig2py, an importable python module for python >= 3.5
- rig2blender for Blender >=2.80
- rig2maya
