Keen Slider — High-Performance Touch Slider and Carousel

Introduction

Keen Slider is a lightweight, framework-agnostic touch slider that delivers a native-like swipe experience. It uses no dependencies, handles gestures natively, and provides smooth momentum-based scrolling on both mobile and desktop.

What Keen Slider Does

• Renders responsive carousels and sliders with touch and mouse support
• Provides native-feeling kinetic scrolling with configurable friction
• Supports multiple slides per view, variable widths, and vertical sliding
• Offers framework bindings for React, Vue, Angular, Svelte, and vanilla JS
• Handles responsive breakpoints with per-breakpoint configuration

Architecture Overview

Keen Slider calculates slide positions and handles gesture tracking in pure JavaScript without DOM manipulation libraries. It uses requestAnimationFrame for smooth animation and pointer events for cross-device input. The core is framework-agnostic, with thin adapter hooks for React, Vue, and other frameworks.

• Set responsive breakpoints with different configurations per screen size
• The CSS file is optional—Keen Slider works with your own layout styles
