Gravitas.js

Engineered for real-time animations with minimal overhead, as demonstrated in live examples like scrolling lists and gesture interfaces that run smoothly even on mobile.

Offers a minimal set of simulations—springs, gravity, friction, bounce—without bloat, making it ideal for targeted UI enhancements without unnecessary complexity.

Allows combining effects like gravity with springs for soft landings, enabling complex behaviors from simple building blocks, as seen in the Fall simulation example.

Includes ready-to-use examples for common scenarios such as buttons, dialogs, and scrolling, reducing integration time and providing clear implementation patterns.
