ColaV Browser Tool Lets VTubers Share One Screen Without OBS Cropping
ColaV attacks the most tedious part of collab streaming, the manual video capture and cropping step in OBS, by turning room participation into the whole compositing workflow, though the host tools sit behind the paid tier.

A browser tool called ColaV is now available for free, letting multiple VTubers appear on a single screen in real time. Developer nico built it so participants share a room code and join, skipping the usual routine of receiving someone's video, cropping it, and importing it into OBS. The free tier only allows joining; room creation is a paid version priced at 1,980 yen as an early access price.
Voice calls are left to everyday tools such as Discord; ColaV concentrates on video, layout, and effects. Participants send an avatar app's screen, a webcam, or images, and every feed lands on one screen. Green backgrounds are chroma-keyed automatically, and webcam video can be cut out to show only the person, so no green screen is needed. Layouts include circle templates plus free drag-and-drop placement. Rooms carry a shared background, game screen sharing, and effects that detect the speaker from microphone volume.
The composited screen opens in its own window and goes into OBS through window capture. A Windows app on BOOTH joins the same rooms as the web version, adds Spout2 output that sends the composite to OBS as one source with transparency preserved, and includes a virtual camera.
