Along with this standard, we're releasing native support for creating, previewing and sharing such interactive animations in the Lottielab editor, similarly to Rive.

We are also releasing Lottielab's Lottie Player, with full support for interactive Lotties and a rich API allowing deep integration in an existing UI.

At Lottielab, we've all worked hard on this for months, and we are excited about the possibilities. I've been deeply involved with this work and am happy to answer HN's questions.
