Recommended animation libraries for complex animations in Svelte / SvelteKit?

[SiamAlSobari]

I’m curious about animation options in the Svelte ecosystem beyond the built-in transitions and motion utilities.

The official animations are great for simple UI interactions, but for more complex scenarios (timeline-based animations, scroll-driven effects, or advanced micro-interactions), are there any community-recommended libraries that work particularly well with Svelte or SvelteKit?

I’ve seen mentions of things like GSAP or Motion One being used with Svelte, but I’m wondering if there are any Svelte-first or Svelte-friendly approaches that the community prefers, especially for larger apps.

Would love to hear what people are using in production and why.

motion-start is svelte 5 compact.
There is also more referenced in motion-start discord

in my experience, AnimeJS is great. It's not particularly a "Svelte-first" library though. Svelte lends itself nicely to giving way to vanilla JS (and CSS) when needed, and AnimeJS shares that in common.

AnimeJS is also beginning to integrate Web Animations API within its toolset, like Svelte transitions is doing. It's a similar ethos. You could see this as either a good thing or potential collision/overlap, but for now I've enjoyed building with both.
