Headless vs Headfull: What the Platform Numbers Actually Mean for Founders

Headless commerce is everywhere in marketing. Here's what the platform adoption data tells us — and what it doesn't.

The headless vs headfull divide

Headfull (traditional): Your frontend (what customers see) and backend (inventory, orders, payments) are tightly coupled. Think Shopify themes, Magento templates, WooCommerce with WordPress.

Headless: Frontend and backend are separated. You use a commerce API (like Shopify Storefront API, commercetools, or BigCommerce) with a custom frontend (React, Next.js, Vue, etc.).

The marketing says headless = faster, more flexible, better performance. The reality is more nuanced.

Ecommerce platform market share

Here's what the market data shows by platform:

Platform adoption by architecture

Traditional vs headless adoption across platforms:

Traditional (Headfull) Platforms

Shopify

~4.5M+ stores globally. ~90%+ use traditional themes. ~10% use headless (Storefront API).

WooCommerce

~5M+ stores. ~95%+ traditional WordPress themes. ~5% headless via REST API.

Magento

~250K+ stores. ~70% traditional. ~30% headless/API-first implementations.

BigCommerce

~60K+ stores. ~85% traditional. ~15% headless via Stencil API.

Headless-First Platforms

commercetools

~500+ enterprise clients. 100% headless by design. API-first architecture.

Contentful Commerce

Growing adoption. Headless CMS + commerce APIs. Primarily enterprise.

Custom Headless

Unknown number. Typically large enterprises with dedicated dev teams.

Key insight: Despite the marketing hype, ~85-90% of ecommerce stores still use traditional architectures. Headless is growing, but it's still the exception, not the rule.

Data Sources:

Note: Headless adoption percentages are estimates based on API usage patterns and platform documentation, as exact numbers are not publicly disclosed by all platforms.

What the numbers don't tell you

Platform adoption stats are misleading because they don't show:

Who's actually going headless

Headless adoption is concentrated in enterprise brands with dedicated development teams and budgets. Small to mid-size brands rarely go headless unless they have specific technical requirements.

The real cost of headless

Headless requires ongoing frontend development. Every design change, every new feature, every bug fix needs developer time. Traditional platforms let non-developers make changes.

Performance isn't guaranteed

Headless can be faster, but it's not automatic. Poor frontend implementation, slow APIs, or bad caching can make headless slower than a well-optimized traditional site.

When headless makes sense (and when it doesn't)

Go headless if:

  • You need complete design control and traditional themes can't deliver
  • You're building for multiple channels (web, mobile app, kiosk, etc.) and need one backend
  • You have a dedicated frontend team and ongoing development budget
  • You're enterprise-scale with complex requirements
  • Performance is critical and you can't achieve it with traditional platforms

Stay traditional if:

  • You're a small to mid-size brand without a dedicated dev team
  • You need to move fast and can't wait for frontend development cycles
  • Your team can make changes without developers (content, design tweaks, etc.)
  • Traditional platforms meet your needs and you're growing
  • You can't afford ongoing frontend development costs

The hidden costs of headless

Headless marketing focuses on flexibility and performance. It rarely mentions:

Ongoing Development

Every design change, content update, or new feature requires developer time. With traditional platforms, non-developers can make many changes themselves.

Complexity

You're managing two systems: backend (commerce) and frontend (custom). More moving parts = more things that can break, more integrations to maintain, more complexity.

Time to Market

Traditional platforms: change theme, deploy. Headless: design, develop, test, deploy. Every change takes longer.

Team Requirements

Headless requires frontend developers. Traditional platforms let marketers, designers, and content creators make changes without developers.

The platform reality check

Here's what the platform numbers actually mean:

Shopify: 90% traditional, 10% headless

Most Shopify stores use themes because they work. The 10% going headless are typically enterprise brands with specific needs. If you're not enterprise, traditional Shopify probably works fine.

Magento: 70% traditional, 30% headless

Higher headless adoption because Magento is enterprise-focused. But even here, most brands use traditional templates. Headless is for complex, multi-channel requirements.

WooCommerce: 95% traditional

WordPress is built for non-developers. Going headless defeats the purpose for most WooCommerce stores. If you need headless, you probably shouldn't be on WooCommerce.

What founders should actually do

Don't choose headless because it's trendy. Choose it because it solves a specific problem:

1. Start traditional

Unless you have a specific requirement that traditional platforms can't meet, start traditional. You can always go headless later if needed. You can't easily go back from headless to traditional.

2. Know your real requirements

Do you actually need headless, or do you just need a better theme? Many "headless requirements" can be solved with modern themes, customizations, or platform features.

3. Calculate total cost of ownership

Headless: Platform costs + ongoing frontend development. Traditional: Platform costs + occasional customization. For most brands, traditional is cheaper long-term.

4. Consider hybrid approaches

Some platforms (like Shopify) let you use traditional themes for most pages and headless APIs for specific features. You don't have to go all-in on either approach.

The real question

The question isn't "Should I go headless?" It's: "What problem am I trying to solve, and what's the simplest way to solve it?"

For 85-90% of brands, traditional platforms solve their problems. For the remaining 10-15%, headless makes sense because they have specific requirements that traditional platforms can't meet.

Don't go headless because you think it's better.

Go headless because you have a specific problem that requires it. Otherwise, traditional platforms are faster, cheaper, and easier to manage.

Final thought

Headless commerce is real. It's growing. It solves real problems for some brands.

But the platform adoption data tells a clear story: Most brands don't need it. Most brands shouldn't do it.

Choose your architecture based on your requirements, not industry trends. Traditional platforms exist because they work. Headless exists for when they don't.
