Going headless promises speed. But if your storefront still loads slowly, or worse, performs worse than your old monolith, you’re not alone.

Many brands go headless for flexibility, design freedom, and better performance. But somewhere along the way, they hit an unexpected bottleneck:

Their “modern” headless storefront ends up painfully slow.

Here’s why that happens and how to fix it.

The Illusion of Performance

When you rebuild your frontend using modern tools like React, Vue, or Next.js, it feels fast at first. It’s slick. It’s animated. It’s code-split.

But speed isn’t about looks or codebase complexity, it’s about how quickly your page renders meaningful content for users.

What really matters is:

• LCP (Largest Contentful Paint)

• Time to First Byte (TTFB)

• Cumulative Layout Shift (CLS)

• Interaction readiness

If you’re not measuring these, you may be shipping an experience that feels modern but performs worse than an old-school Shopify theme.

Why Headless Goes Wrong

Let’s break down some of the most common performance traps in headless commerce builds:

1. No SSR or Incomplete Rendering

Many headless frontends rely on client-side rendering (CSR), where the entire page is built in the browser,often after the JS bundle loads. That leads to blank screens and delays in rendering content.

2. Overloaded APIs

If your storefront calls 12+ APIs on load (products, navigation, cart, CMS, search, personalization...), each API adds latency. Add third-party services and you’ve got a recipe for slowness.

3. Image Problems

Without automated optimisation, images are often:

• Uncompressed

• Not lazy-loaded

• Served in old formats (PNG, JPG instead of WebP or AVIF)

That hurts your Core Web Vitals and mobile experience.

4. No Edge Delivery

If your frontend isn’t deployed globally via CDN with caching at the edge, your users (especially international ones) suffer from high TTFB.

5. No Performance Ownership

Agencies or internal dev teams may optimize for delivery, but not long-term performance. Who owns Lighthouse scores after launch? Who monitors page speed monthly?

The Real Cost of a Slow Headless Store

• Higher Bounce Rates – Mobile users especially won’t wait more than 3 seconds

• Wasted Ad Spend – You pay for every click; a slow page destroys the funnel

• Lower SEO Rankings – Google uses page speed & Core Web Vitals in rankings

• Reduced Conversion Rates – Even a 100ms delay can impact sales

Your tech stack shouldn’t cost you revenue.
