Kalidoface 3D review
A browser-based avatar tracker with broad capture tools and OBS support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Kalidoface 3D is an open-source, browser-based application for applying facial, full-body, and hand movement to VRM 3D avatars. It is aimed at Vtubers, creators, and developers who want camera-based, real-time avatar tracking through a web browser. Users can access the application live, upload a custom VRM model by dragging and dropping it into the interface, and use a webcam as the capture source. The project also references a standalone JavaScript tracking library for developers building Vtuber applications.
Its strongest advantage is breadth within a browser-first avatar workflow. Face tracking uses 3D avatar controls, full-body tracking uses MediaPipe pose detection, and hand tracking is provided through the standalone tracking library. The application also supports custom image backgrounds, chroma-key colors, resizable image and GIF stickers, and private voice calls using virtual avatars. OBS browser-object integration makes it suitable for creators who want to bring the tracked avatar scene into an OBS-based production setup without leaving the web workflow.
Kalidoface 3D fits users who specifically want open-source browser avatar tracking with VRM support and a useful set of presentation tools. It is a less natural fit for teams seeking a desktop-native motion-capture pipeline, broader production integrations, or workflows centered on formats beyond VRM avatars. The browser-only platform and webcam capture model keep the product focused: choose it for accessible Vtuber tracking and lightweight broadcasting features, rather than as a general-purpose motion-capture system.
