Does Cosmic work with React frameworks like Next.js, Remix, and Gatsby?

Yes. Cosmic works with any React-based framework. The REST API is framework-agnostic, so you can fetch content in Next.js Server Components, Remix loaders, Gatsby build-time queries, or plain client-side useEffect hooks. There are no proprietary adapters required.

How do I fetch content from Cosmic in a React app?

Make a GET request to the Cosmic REST API using the native fetch API or any HTTP client. Pass your bucket slug and read key as parameters, and filter by content type. You can use this in a useEffect hook for client-side fetching, or directly in a Next.js Server Component for server-side rendering. See the code examples above.

Can non-developers edit content without touching React code?

Absolutely. Cosmic includes a visual content editor that editors and marketers can use independently. Content changes are made in the Cosmic dashboard and delivered via API. Your React code never needs to change for a content update.

What does Cosmic cost?

Cosmic has a free tier that includes 2 users. Paid plans start at $19/month (Builder, 3 users), $99/month (Team, 5 users), and $299/month (Business, 10 users). Additional users on any paid plan are $29/user/month. Enterprise pricing is available for larger teams.

Headless CMS for React

Why React Developers Choose a Headless CMS

React's component-based architecture changed how we build UIs. Every piece of the interface is a discrete, reusable unit. Your CMS should work the same way.

A traditional CMS couples content to presentation, which creates friction the moment you want to render the same content in a React web app, a mobile app, or a kiosk display. A headless CMS removes that coupling. Content lives in a structured API layer; your React components consume it however they need to.

The practical benefits for React teams:

Separation of concerns. Content editors work in a clean visual interface. Developers work in code. Neither blocks the other.
True flexibility. Fetch content into any component tree, any routing pattern, any deployment target.
Performance control. You decide how and when to fetch: at build time, on the server, or from the client. The CMS gets out of the way.
Composable content. Model your content as structured data, then compose it exactly the way your components expect.

When your content infrastructure matches your frontend architecture, building and maintaining React apps gets significantly faster.

How Cosmic Works with React

Cosmic exposes all your content through a clean REST API. There's no proprietary client you're required to use. A standard call is all you need.

Fetching Content in a React Component

Here's a real working example using in a functional component:

Using React Server Components (Next.js App Router)

If you're using Next.js with the App Router, you can fetch content directly in a Server Component without any client-side state:

Two environment variables. One REST call. Your content is in your component.

Key Features for React Teams

Flexible Content Modeling

Define your own content types and fields without being locked into a rigid schema. Need a object with an image, a headline, and a CTA? Build it. Need a structured product catalog with nested metadata? Model it. Cosmic adapts to your data shape, not the other way around.

Media Management with imgix

Every image uploaded to Cosmic is automatically served through imgix, a best-in-class image CDN. Resize, crop, format, and optimize images at the URL level. No image processing pipeline to maintain.

Environments

Cosmic gives you separate environments for development, staging, and production. Test content changes safely before they reach your live React app.

Preview Mode

Enable real-time content preview so editors can see exactly how their changes look in your React frontend before publishing. Works seamlessly with Next.js draft mode and other React framework preview APIs.

Team Collaboration

Content editors, marketers, and developers can all work in the same CMS without stepping on each other. Role-based permissions keep the right people in the right places. Plans include between 2 and 10 seats, with additional users at $29/user/month.

What Teams Are Saying

"Cosmic is: us never having to ask a developer to change anything on the backend of our website."

Maximilian Wuhr, Co-Founder at FINN

FINN, the Munich-based automotive subscription company, uses Cosmic to give their marketing team full content autonomy. Their developers ship features. Their editors ship content. No bottlenecks.

Works with Every Major React Framework

Cosmic is framework-agnostic. If it renders React, it works with Cosmic:

Next.js (Pages Router and App Router, including ISR and Server Components)
Remix (loader functions fetch from the Cosmic REST API directly)
Gatsby (source plugin or direct REST API calls at build time)
Vite + React (client-side fetching for SPAs)
Astro with React islands

No framework-specific adapters required. The REST API works everywhere.
