It wouldn’t be in the source code, unless the animation is actually a slideshow that’s being generated by JavaScript.  (Which is useful to allow people to speed up or speed down animations for analysis purposes)

Most others will just tell you the file type, which won’t necessarily tell you what created the file.

If you download it, and open it in an appropriate viewer, you can try to check if there is any metadata attached.  Sometimes the software will write something in there about who and what created the file.
