Ultraleap Tracking WebSocket
An open-source WebSocket server from Ultraleap that restores the LeapJS-compatible websocket surface removed when Leap Motion Orion V4 was replaced by Ultraleap Gemini V5. It streams tracking data over the legacy LeapJS "v6" JSON protocol so browser applications can consume hand tracking. It runs locally alongside the tracking service; the endpoint is a loopback WebSocket, not a hosted API.
