Leap Motion? Ultraleap?
Leap Motion, created in 2013, was the company that created the original Leap Motion Controller and the hand tracking software. In 2019, it merged with Ultrahaptics, and the resulting company was renamed to Ultraleap. This page will still refer to some software version as "Leap Motion" as this how they are presented on the Legacy downloads page on the Ultraleap developer's website.

Programming languages support
This table won't take in account community-made bindings, I will only list languages that are officially supported by Ultraleap. Because language support is tied to which API is supported, we will list language support per API instead of per SDK version.

Game engine supports
I haven't looked to find if the Unity and Unreal plugins were still publicly available for Leap Motion 2.x and Leap Motion 3.x. This table is incomplete and shouldn't be trusted.
Looking for the latest plugins themselves? The headers of the table have public links to them.
