We at Touchlab recently researched Lottie animation libraries in Compose Multiplatform and wrote a short blog post about it. If you are also interested in this topic, it may be helpful to you 🙂

This is probably not the best place, but kudos to @Ismail and @Alexander Zhirkevich for implementing these great libraries pepe clap

You can play with Compottie in web LottieFiles search app.
All animations are rendered using pure Kotlin renderer.
Safari runs this app using JS so it is lagging as 💩. Browsers with wasm support handle it way better

Browsers with WASM support handle it way better

They do; see the Compose Test Card tab here.

Interesting that there are these extra libraries; I found the Skottie feature already hiding within Skia - do they make this feature more ergonomic to use or are they new standalone implementations?

Yep. I just meant that the app can automatically fallback to JS when it can't detect wasm GC

Indeed. But it doesn't support images and fonts (they aren't properly exposed in skiko) and in general some animations run differently there

Compottie is a standalone multiplatform implementation that produces simple Compose Painter consistent on all platforms. Kottie is a wrapper of Skottie, lottie-android and lottie-ios with native views and all its pros and cons
