Scroll Synced Lottie: Free Interactions Component by FunTech

Hook your Lottie animation to a section’s scroll and play it smoothly as users scroll. Fine-tune the feel with flexible Transition settings for responsive, silky-smooth motion.

Scroll Synced Lottie lets you connect a Lottie JSON to the scroll position of the component itself. By setting two offset intersections between the target (this component) and the viewport, it maps that range to a normalized 0→1 progress and updates the animation accordingly—perfect for step-by-step storytelling, and hero effects.

Features

Scroll-position hookup: Drive Lottie directly from scroll progress
Intersection: Control when the animation reacts using just two offsets
Flexible Transitions: Adjust motion response via Transition (spring or tween)
