Lottie.js is a library for animations in JavaScript, and after effects can export to it! You're obviously limited in what you can export, but if you do a basic after effects animation with shapes and text, it works fine.

Pretty sure it was made by Airbnb, and used in tons of apps like Google home

Works really well

There are free tools to create lottie animation, Synfig in particular supports it.
