Lenis

Lenis is a smooth scroll JavaScript library that creates fluid, momentum-based scrolling experiences for modern websites. The library enhances the native browser scrolling behavior with customizable easing functions and inertia effects. Lenis is lightweight and framework-agnostic, working seamlessly with vanilla JavaScript or frameworks like React and Vue. It provides a simple API for controlling scroll behavior, direction locking, and programmatic scrolling. The library is particularly popular for creating polished, app-like scrolling on creative agency websites and interactive portfolios. Lenis handles both mouse wheel and touch gestures with optimized performance for smooth 60fps animations. The library integrates well with animation frameworks like GSAP for complex scroll-triggered animations.
