slowmo: Control Animation Speed in Any Web Page

slowmo: a JavaScript library that gives you full playback rate control over every animation on a web page, CSS transitions, canvas loops, videos, GSAP, Three.js, and Framer Motion, from a single function call.

Key features:

• slowmo(0.5) — half speed. slowmo(0) — paused. That's the entire core API.
• Patches requestAnimationFrame, performance.now(), Date.now(), and the Web Animations API simultaneously
• Optional draggable Dial UI for Vanilla JS and React
• data-slowmo-exclude attribute to opt specific elements out
• Auto-detects and integrates with GSAP natively
• Zero dependencies, MIT license
