Heygen Alternative

Duix (formerly HeyGem) is the open-source HeyGen clone — it clones a face from a short video and re-lip-syncs it to any audio, offline on an NVIDIA card. We installed it and ran it. Here’s the honest result.

LongCat animates a whole body — gestures, lean, face, mouth — from audio, locally, for free. Long takes in one job. It’s our pick for a full-body local host, with two honest caveats: a quiet background, and drift on very long takes.
