What is headless BigCommerce?

Headless BigCommerce decouples the frontend presentation layer from the BigCommerce backend. The frontend (built in React/Next.js) communicates with BigCommerce via Storefront API. This enables sub-second load times, full design freedom, and best-of-breed tool integrations impossible in a traditional Stencil theme.

When should I use headless BigCommerce vs Stencil?

Use headless BigCommerce when you need: sub-second Core Web Vitals, a custom CMS for content editors, complex UI interactions impossible in Stencil, composable commerce integrations (Algolia, Contentful), or multiple brand frontends from one backend. For simpler stores, Stencil is faster to build and maintain.

What is the BigCommerce Storefront API?

The BigCommerce Storefront API is a GraphQL API that exposes product, catalog, cart, checkout, and customer data to headless frontends. IWD engineers are expert Storefront API users with extensive knowledge of performance optimization, caching strategies, and edge case handling.

How much faster is a headless BigCommerce store?

Properly built headless BigCommerce storefronts typically score 90+ on Lighthouse performance, with LCP under 2.5 seconds. Traditional Stencil themes typically score 40-70 depending on app load. The performance improvement translates directly to SEO rankings and conversion rates.

Can I use a headless CMS with BigCommerce?

Yes. We integrate headless BigCommerce with Contentful, Sanity, and Prismic. Content editors manage copy, images, and layouts independently from product data. Engineering deployments are only required for code changes, not content updates.

How long does a headless BigCommerce build take?

Standard headless BigCommerce storefronts take 12-20 weeks. Full composable commerce builds with CMS and search integrations take 18-28 weeks. Timeline confirmed during architecture planning phase.

Can a headless BigCommerce store support B2B?

Yes. We build headless frontends for BigCommerce B2B Edition with custom buyer portal UX, complex pricing displays, and approval workflow interfaces. See our BigCommerce B2B services.

What hosting do you recommend for headless BigCommerce?

We recommend Vercel for Next.js headless BigCommerce builds due to its edge network, seamless Next.js support, and preview deployment workflow. AWS (Amplify or CloudFront) is our alternative for enterprise brands with existing AWS infrastructure.

Can I migrate from Stencil to headless BigCommerce?

Yes. We plan and execute Stencil-to-headless migrations with zero downtime, SEO preservation, and parallel QA before cutover. See our BigCommerce migration services.

Do you do SEO for headless BigCommerce?

Yes. Headless BigCommerce with server-side rendering has full SEO capability. We implement structured data, canonical tags, hreflang, and sitemap generation in Next.js. See our BigCommerce SEO services.

When is headless BigCommerce worth the complexity?

Three triggers usually justify it: a content-heavy storefront where editorial flexibility matters more than theme convention, a multi-brand operation that needs a unified shell across catalogs, or a store above 10 million in GMV where sub-2-second LCP directly affects conversion. Below those bars, a well-built Stencil theme usually wins on cost-to-launch.

What's the LCP target on a headless BC build?

Sub-2-second LCP on PDP and PLP is achievable and is our default target. The mechanics: Next.js with React Server Components, edge-cached BC GraphQL Storefront API responses, optimized images via Cloudinary or Netlify Image CDN, and ISR for catalog pages. Lab Lighthouse 90+ across CWV is the build-acceptance threshold.

Can we keep BigCommerce as the back-office and go headless on the front?

Yes. That's the standard headless BC architecture. Catalog management, orders, customers, inventory, and admin all stay in BigCommerce. The Next.js or Astro front-end consumes BC via the GraphQL Storefront API. Checkout can stay on BigCommerce hosted or use BC's Embedded Checkout.

What CMS works best with headless BigCommerce?

Sanity, Contentful, and Storyblok all integrate cleanly. We default to Sanity for teams that want strong editorial workflows and real-time collaborative editing. Contentful fits enterprise teams with formal content-modelling needs. Storyblok fits visual-editing-heavy marketing teams.

How does headless BC handle SEO?

Identical to a themed BC store in terms of canonical signals, structured data, sitemap, and robots. The front-end has more control over things like schema injection, hreflang, and CWV. We treat SEO as a first-class concern in the front-end architecture: server-rendered metadata, JSON-LD on every product/category, edge-cached sitemap regeneration.

What's the timeline and team for a headless BC project?

10 to 16 weeks typical. Team: 2 to 3 senior front-end engineers, 1 BC integration engineer, 1 designer, 1 project lead. Phase 1 is architecture and design system, phase 2 is the build, phase 3 is QA and DNS cutover, phase 4 is the post-launch performance and SEO monitoring sprint.

BigCommerce headless: when it's worth it, and what we build

BigCommerce headless decouples your storefront from the BC backend, giving you Next.js or Astro on the front end and BC's GraphQL Storefront API on the back. We build headless BigCommerce stores when teams need editorial flexibility, sub-2-second LCP at scale, or a unified shell across B2B and DTC.

Stencil vs headless on BigCommerce

Dimension	Stencil (themed)	Headless (Next.js/Astro)
Time to launch	4–8 weeks	10–16 weeks
Front-end LCP	2.5–4s typical	Sub-2s achievable
Editorial control	Page builder + theme files	Sanity / Contentful / Storyblok
B2B + DTC under one shell	Two themes or two stores	Routing-level split (one repo)
Search experience	BC native or Searchspring app	Algolia / Typesense / Constructor.io
Cost to maintain	Lower (theme + apps)	Higher (front-end + infra)
Best for	Catalog-driven stores under $10M	Content-heavy, multi-brand, or $10M+ GMV

Our headless BigCommerce stack

Next.js 15 storefront

App Router, React Server Components, ISR for product/category pages, edge-cached on Vercel or Netlify. Catalyst-based or fully custom.
