Lenis is a lightweight, performant smooth‑scroll library (written in JavaScript) that adds buttery‑smooth scrolling, scroll‑syncing, parallax and other kinetic effects to web pages, with a tiny footprint and no‑frills API. It’s aimed at developers who want to enhance user experience on modern browsers—especially for WebGL scenes, image grids, animations, or any site that needs polished scroll dynamics without heavy dependencies.
