I'm always amused by this question.

There is, it's called Adobe Animate, its what they rebranded Flash as, it's literally the same thing. It exports straight to Canvas and WebGL using the create.js libraries. [0]

Basically the online advertising space had a collective heart attack when Flash was suddenly deprecated because they used Flash for all their banner animations. Adobe tried to replace Flash with Edge [1], which was one of the slowest and buggiest program I ever used. It didn't last long.
