Ultraleap Limited (Bristol, UK) is the hand-tracking and mid-air haptics company formed in 2019 when Ultrahaptics acquired Leap Motion. It ships the Leap Motion Controller 2 and Stereo IR 170 / 3Di hand-tracking cameras, the Ultraleap Hand Tracking Software (Gemini V5, now Hyperion V6) with its native LeapC C API, first-party Unity and Unreal plugins, an implicit OpenXR API layer implementing XR_EXT_hand_tracking, Python bindings, a LeapJS-compatible tracking WebSocket server, and the TouchFree touchless interaction tooling for web and Unity. Its ultrasonic haptics SDK is supplied on request rather than published. The developer surface is a locally installed SDK and service, not a hosted HTTP API, so there is no OpenAPI or base URL. In 2025 the company announced it is joining ROLI, the music-technology company.
