Blender is described as 'is the free and open-source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing, video editing, and motion tracking' and is a leading 3D Modeler in the Photos & Graphics category. There are more than 100 alternatives to Blender for a variety of platforms, including Windows, Mac, Linux, Online / Web-based and iPad. The best alternative is Autodesk Maya. It's not free, so if you're looking for a free alternative, you could try Wings 3D or Natron. Other great apps like Blender are Autodesk 3ds Max (Paid), Cinema 4D (Paid), Bforartists (Free, Open Source) and VRoid Studio (Free).
