Framer Motion is a open-source animation library for React with declarative syntax and gesture support. It handles react animations, gestures, layout animations, and svg, and it's best suited for react developers who need animation. It has been around since 2019, giving it a 7-year head start in building out integrations and refining the product.

The core product is entirely free. Since it's open-source, you can self-host for free with no user limits. It's aimed at individual users, so it's fast to set up but may lack team-management features if you scale.
