Why Your Framer Website Is Slow (and What You Can Do About It)

You built a beautiful site in Framer. The animations are smooth in the editor, the design looks polished, and everything feels fast on your MacBook Pro. Then you run a PageSpeed test and see a score of 45.

You're not alone. Many Framer sites score below expectations on Google's Core Web Vitals - particularly on mobile. Let's look at why that tends to happen, and what you can do about it.

The Performance Numbers

We've audited dozens of Framer sites over the past year. The pattern is consistent:

These are typical ranges we've seen across Framer business sites with animations, CMS content, and custom components. Simpler sites may perform better, but complexity tends to push scores down.

Why Framer Sites Can Be Slow

Heavy JavaScript Bundle

Framer ships a large JavaScript runtime to every page. This runtime powers the animation engine, the CMS rendering, and the component system. Even a simple landing page with minimal content loads 200-400KB of JavaScript before your actual content appears.

On a mid-range Android phone with a 4G connection, parsing and executing that JavaScript takes 1-3 seconds. That's before your images load, before your fonts render, before the user sees anything useful.

Client-Side Rendering

Framer renders pages primarily on the client side. The browser downloads HTML, then JavaScript, then the JavaScript builds the page. Compare this to Next.js, which sends fully-rendered HTML from the server - the browser displays content immediately while JavaScript loads in the background.

This is why your Framer site feels fast on your laptop but scores poorly on PageSpeed. The test simulates a real mobile device on a real mobile connection, not a MacBook on fiber.

Animation Overhead

Framer's animation system is powerful but expensive. Every scroll-triggered animation, hover effect, and page transition adds to the JavaScript execution cost. Animations that feel smooth on desktop can cause visible jank on mobile devices with less processing power.

Limited Image Optimization

Framer handles basic image optimization, but you have no control over formats, quality settings, or responsive sizing strategies. Next.js's Image component automatically serves WebP/AVIF in the right dimensions for each device, with lazy loading and blur-up placeholders. The difference in image payload alone can be 50-80%.

What You Can Do Within Framer

If you want to stay on Framer, there are meaningful improvements you can make:

• Reduce the number of animations - each one costs performance
• Compress images before uploading instead of relying on Framer's optimization
• Minimize custom code overrides and embedded scripts
• Remove unused components and sections
• Avoid deeply nested component structures

Realistically, these optimizations can improve your score by 10-15 points. If you're at 45, you might reach 55-60. Still below Google's threshold for "good" performance.

Why This Matters for Your Business

Google uses Core Web Vitals as a ranking signal. A slow mobile experience means lower search rankings. Beyond SEO, 53% of mobile visitors leave a site that takes longer than 3 seconds to load (Google data). If your Framer site's LCP is 4+ seconds, you're losing visitors before they see your content.

For sites that depend on organic traffic or paid ad conversions, poor performance directly impacts revenue. Every 100ms of additional load time reduces conversion rates by approximately 1%.

The Alternative

A Next.js rebuild preserves your design while fixing the underlying performance issues. The visual output stays the same - same layout, same animations, same brand identity. The delivery mechanism changes from client-rendered JavaScript to server-rendered HTML with optimized assets.

The result is typically a jump from 45-65 on mobile PageSpeed to 92-99. Same design, dramatically better performance. Better rankings, lower bounce rates, higher conversions.

If your Framer site is a business tool - not just a portfolio piece - performance should be a priority. Run your site through PageSpeed Insights on mobile and see where you stand. The numbers will tell you whether in-platform optimization is enough or whether you've reached the limits of what Framer's architecture can deliver for your use case.
