What a Gatsby to Webflow Migration Involves

Gatsby was built for performance-obsessed development teams — static site generation, GraphQL data layers, and a React component model that produces fast, SEO-friendly sites. The cost is operational complexity: Gatsby requires ongoing engineering for builds, dependency updates, plugin compatibility, and any content or design change that touches the component layer. For organizations where the maintenance burden has outpaced the performance benefit, Webflow delivers comparable performance — and often better Core Web Vitals scores — with dramatically lower operational overhead.

What the Migration Covers

Composite migrates Gatsby sites to Webflow across three layers. The design layer is rebuilt in Webflow's Designer with component fidelity — replicating the visual system without porting the React component architecture. The content layer migrates from Gatsby's data sources (Contentful, Sanity, markdown files, or other headless CMS) into Webflow CMS Collections with appropriate field mapping. The integration layer re-engineers any Gatsby plugins or API connections using Webflow's native integration ecosystem or custom code where necessary.

Frequently Asked Questions

Will Webflow match Gatsby's performance scores?

In practice, yes — and often surpasses them for teams that haven't actively maintained Gatsby's performance optimizations. Webflow sites on Fastly's CDN with clean generated HTML score consistently well on Core Web Vitals without requiring performance engineering effort.

What happens to our Gatsby plugins and data sources?

Gatsby plugins are evaluated individually. Most provide functionality that either exists natively in Webflow (SEO, image optimization, responsive design) or can be replicated with Webflow's integration ecosystem. Data sources — headless CMS, APIs — are migrated into Webflow's CMS or reconnected via custom code depending on the use case.

Can Webflow handle Gatsby's static site generation approach?

Webflow generates static HTML at publish time and serves it from a CDN, which is functionally equivalent to Gatsby's static site generation for most marketing use cases. Dynamic, real-time data requirements are handled via client-side JavaScript and API calls where needed.

How long does a Gatsby to Webflow migration take?

Gatsby migrations typically take 4 to 8 weeks depending on content volume, data source complexity, and design scope. Sites with large content libraries or complex Gatsby plugin dependencies take longer and are scoped individually.
