Add GSAP DrawSVG (https://gsap.com/docs/v3/Plugins/DrawSVGPlugin/) and you've nearly rebuilt Macromedia Flash!

The obvious question is, what does free mean? Here's the license:

Basically freeware with express prohibitions on competing with Webflow.

GSAP[1] is pretty much the industry standard, I think. You have to pay for some of its more advanced features.
There's also Anime.js[2] and Scene.js[3] - but I've never played with them so can't vouch for their usefulness. Both have had code updates in the past year.
(Self-promotion time) I had a lot of fun adding an animation/tween system to my canvas library[4] a while back. Building out the code to run such animations is one thing; making it performant is a very different challenge![5]

Yes this was done with a combination of GSAP Scrolltrigger https://gsap.com/docs/v3/Plugins/ScrollTrigger/ and https://d3js.org/

Another goofy, non-standard license[1] that hasn't been vetted by anybody, and isn't well understood. Weird terms like "You can only use this in no-charge software, but if you only charge the user once you can use it." and "If you use this in subscription / usage fee software, please buy a commercial license." So is that a request, or a strict condition? Thanks, but no thanks.
