Moho

Artists draw in vector, build a skeleton of bones, and animate poses instead of redrawing every frame. Smart Bones and physics help with reusable controls and secondary motion. Output goes to video and many game formats.

It is popular with independent animators and small studios because it is cheaper than studio tools. Larger productions often choose Toon Boom Harmony.

Cartoon Animator and Adobe Animate are alternatives. Moho suits animators who want rigging at an accessible price.
