Most teams reach the same wall at different speeds. Your content is buried inside a platform that tightly couples your editing experience, your schema, and your delivery layer. You can't serve the same content across a mobile app, a web app, and a third-party integration without duplicating work.
Migrating to a headless, API-first CMS changes this. Your content becomes a structured data layer that any frontend can consume, your editors keep a clean dashboard, and your developers get a REST API and SDK they can query from anywhere.
The migration itself has always been the hard part. Until now.
Cosmic Migrate: Point It at Your Site, and It Does the Work
Cosmic's migration tool removes the manual work that makes migrations painful. You point it at your existing site, and it:
- Analyzes your pages and content structure
- Proposes a content model with the right object types, metafields, and relationships
- Migrates your content into a structured, API-first CMS with a clean REST API and JavaScript/TypeScript SDK ready to use
It supports WordPress, Webflow, Ghost, and Shopify out of the box. No CSV exports, no manual field mapping, no writing migration scripts from scratch.

Why Teams Migrate to a Headless CMS
The content is locked to one delivery layer. WordPress, Webflow, and Ghost were built to put content on web pages. Serving that same content to a mobile app, a kiosk, or a third-party integration requires workarounds or rebuilding the content in a separate system. A headless CMS stores content as structured data and exposes it via API. Your content team edits once. Every surface consumes from the same source of truth.
The schema is rigid. WordPress gives you posts, pages, and custom post types with plugin overhead for anything more complex. In a headless CMS, you define exactly the content model your project needs.
Developer velocity slows down. When developers need to change how content is structured, they are often waiting on backend changes in a monolithic CMS. In a headless setup, the CMS is infrastructure. Neither the frontend team nor the content team blocks the other.
This is the value teams like FINN experience directly. Maximilian Wuhr, Co-Founder at FINN, put it plainly: "Cosmic is: us never having to ask a developer to change anything on the backend of our website."
Migration Paths by Platform
From WordPress to a Headless CMS
Cosmic Migrate analyzes your WordPress site's structure, identifies your post types and fields, proposes equivalent Object Types and metafields in Cosmic, and migrates your content and media. Your WordPress posts become objects. Your ACF fields map to metafields. Your media uploads to Cosmic's media library.
From Webflow to a Headless CMS
Cosmic Migrate reads your Webflow Collection structure and maps it to Cosmic Object Types. Plain Text fields become metafields. Reference fields become relationship metafields. After migration, your Webflow Collections are Cosmic Object Types accessible via the REST API.
From Ghost to a Headless CMS
Cosmic Migrate ingests your Ghost export and creates objects in Cosmic with your posts' content, tags, authors, and featured images. Your Ghost JSON becomes a structured Cosmic bucket ready to query.
From Shopify to a Headless CMS
Cosmic Migrate analyzes your Shopify store and migrates your blog posts, pages, and editorial content into Cosmic. Product data typically stays in Shopify; Cosmic handles the content layer.
How the Migration Process Works
- Go to cosmicjs.com/migrate and enter your site URL or upload an export file
- Cosmic analyzes your site and surfaces a proposed content model
- Review the proposed Object Types and metafields. Adjust if needed
- Confirm the migration. Cosmic creates your Object Types, migrates your content, and uploads your media
- Connect your frontend with the Cosmic SDK and your bucket credentials
For most sites under a few hundred pages, the analysis and migration complete in minutes.
Real Teams, Real Results
FINN moved their marketing content to Cosmic and removed the developer bottleneck from their content publishing workflow entirely.
Parque Explora, Colombia's largest science and technology museum, uses Cosmic to power multilingual content delivery across their digital properties.
Eastman Music runs their product catalog and editorial content through Cosmic, serving content via the REST API.
Vuetify uses Cosmic to manage their documentation and community content.

If your content is locked inside a platform that slows your team down, the path out is now much shorter.
