Best free auto-rigging and AI animation tools (2026)
Picks based only on what each vendor's own pricing and terms pages say (checked 2026-10-15): can you ship it, what it costs, and whether your agent can call it. We don't rank by output quality.
Free and royalty-free in games
Adobe's Mixamo FAQ says characters and animations are royalty-free for personal, commercial and non-profit projects, including video games. It needs an Adobe ID.
Free auto-rigging, licence unverified
Reallusion's AccuRIG is free. Reallusion's Software EULA allows game use of exported models, but its grant is worded for purchased or subscribed software, so how it covers free AccuRIG is unclear. Ask Reallusion before shipping.
AI motion capture from video
Rokoko Vision (AI mocap), DeepMotion Animate 3D (AI mocap)
Rokoko's free Starter plan includes 30 s/month of video-to-motion and its FAQ allows commercial use; DeepMotion's free tier (25 credits/month) is non-commercial.
Keyframe animation with AI assist
Cascadeur's free tier is non-commercial; Indie allows commercial use under $100k/yr revenue.
