Speeding Up Framer Sites
Framer creates beautiful interactive sites, but they can be heavy. Learn how to optimize Framer sites for better Core Web Vitals.
Framer has become the go-to tool for designers building production websites. Its visual editor produces beautiful, interactive pages — but those interactions come with JavaScript that can hurt performance. Here's how to optimize.
Why Framer Sites Can Be Slow
JavaScript-Heavy Runtime
Framer uses React under the hood. Every interaction, animation, and component ships as JavaScript. A typical Framer site sends 300-800KB of JavaScript.
Animation Overhead
Framer's animation engine (powered by Framer Motion) is powerful but adds weight:
- Base Framer Motion library: ~30KB
- Each animated component: additional JavaScript
- Complex scroll-based animations: continuous main thread work
Component Architecture
Framer components are React components. Each adds:
- JavaScript for rendering
- CSS for styling
- Event listeners for interactions
Optimization Strategies
1. Reduce Animation Complexity
- Use CSS transitions instead of Framer Motion where possible
- Limit scroll-based animations (they run on every scroll event)
- Use
will-changesparingly - Prefer
opacityandtransformanimations (GPU-accelerated)
2. Optimize Images
- Use Framer's built-in image optimization (auto-WebP)
- Set appropriate image sizes in the editor
- Don't use full-resolution images as backgrounds
- Enable lazy loading for below-fold images
3. Minimize Page Complexity
- Limit sections to 8-10 per page
- Avoid deep component nesting
- Use simple layouts where possible
- Remove unused components from the canvas
4. Reduce Third-Party Scripts
Each integration adds weight:
- Analytics: Use Framer's built-in analytics or a single GA4 script
- Chat widgets: Load on click instead of page load
- Social embeds: Use static images linked to social profiles
5. Use Code Components Wisely
Custom code components in Framer should be lightweight:
// Keep code components simple
export default function Badge({ text }) {
return (
<span style={{
background: 'rgba(59, 130, 246, 0.1)',
color: '#60a5fa',
padding: '4px 12px',
borderRadius: '9999px',
fontSize: '12px',
}}>
{text}
</span>
);
}
Framer Performance Checklist

- Below-fold images lazy loaded
- Minimal third-party integrations
- Hero section loads without JavaScript (if possible)
- Custom fonts limited to 2 families, 3 weights max
