So animated GIFs can be replaced by Animated PNGs with alpha blending with transparent backgrounds and lossless compression! Some nostalgia from 2000s websites can be revived and relived :)

Curious if Animated SVGs are also a thing. I remember seeing some Javascript based SVG animations (it was a animated chatbot avatar) - but not sure if there is any standard framework.

Almost nowhere that supports uploading GIFs supports APNG or animated WEBP. The back end support is so low it's close to zero. Which is really frustrating.

Do you mean services that reencode gif files to webm/mp4? apng just works everywhere that png works, and will remain animated as long as it's not re-encoded.

You can even have one frame that gets shown if and only if animation is not supported.

Yes, most places only show the first frame. They ignore the animation, sadly. Even while accepting GIFs.
