Janus

Janus provides a real-time character animation platform that uses a webcam to render a 3D avatar directly in the browser. It supports streams on Discord, Zoom, Twitch, YouTube, and other platforms without requiring special hardware or setup. The tool is designed for creators who want presence, personality, and privacy while streaming or video calling. The avatar is generated from a photo or prompt and animates to reflect facial expressions and movements in real time.

Janus operates with local rendering in the browser, meaning there are no cloud servers used during streaming. The web-based system processes the animation on the user’s device, guided by facial tracking, delivering a live avatar right in the user’s browser. It supports streaming to major platforms and is intended to work across devices with compatible browsers.

Users can customize and evolve their avatar after creation. They can change outfits, hairstyles, accessories, and backgrounds at any time to adapt to different moods, scenes, and contexts. The platform emphasizes ease of use and accessibility by relying on a standard webcam and microphone, and by avoiding expensive hardware.

Janus plans offer a free tier and a pro tier.
