Janus (janus.cam) is a real-time avatar platform for streamers, VTubers, remote workers, and content creators who want to appear on camera as a completely different character. You upload a selfie or describe a character, and Janus generates a 3D avatar that renders directly in your browser. Your webcam then tracks your face and drives the avatar's expressions and motion at full HD, so you can broadcast on Twitch, YouTube, Discord, Zoom, Google Meet, or any app that accepts a virtual camera.
What separates Janus from cloud-rendered avatar tools is that streaming happens locally on your device as a Gaussian splat, so there is no server round-trip and no lag during live sessions. It works on macOS, Windows, Linux, and mobile through a modern Chromium-based browser, with no dedicated GPU or motion-capture rig required. Avatars can be refined after creation — outfits, hairstyles, accessories, and backgrounds can all be adjusted to suit a new mood or scene.
Pricing starts with a free tier that includes unlimited streaming and access to ready-made avatars, with credits available through one-off top-ups or a monthly Pro plan. Pro adds 60fps+ streaming, green screen support, watermark removal, expression fine-tuning, and monthly credit allowances. Janus states that uploaded photos and webcam footage are not stored on its servers.
