Cosmic JS Features Cosmic JS empowers developers and content editors to build great products together.

Tools that empower your team

Cosmic JS is a powerful content platform that makes it easy to transform your content into a beautifully simple API which can be used in any website or internet-connected application. Developers are enabled to build freely and easily, content editors can intuitively edit content and everyone saves time in the process.

Cross-Platform, API-First

Cosmic JS takes an API-first approach to content management and is not tied to any programming language, so your content can be available on any website or application and across devices. Your content is accessed through the JSON API and can be made available everywhere. Say good bye to development time lost in CMS installation, configuration and maintenance.

Easy Web App Deployment

Cosmic JS makes it easy to deploy your web app from any public Git repository as well as your GitHub private repos. Just sign in with GitHub to connect your account and deploy your app to your dedicated hosted instance on the Cosmic JS app server.

You can also add unlimited custom domains with an upgraded bucket. Cosmic JS is your easy web hosting and content management solution in one!

Intuitive Creation Dashboard

The Cosmic JS dashboard makes it easy to manage content, drag and drop media and build content relationships. Developers are provided with powerful tools to build full-featured applications and content editors are given a simple and intuitive way to manage content.


Localization allows you to add multiple versions of your content in different languages. Cosmic JS makes localization easy so your content can reach a global audience.


Webhooks automatically send data to the URL of your choice whenever content is edited in your Cosmic JS bucket. For example, this can be used to trigger a static site rebuild or notify your team on Slack™ when content has been changed in your bucket.

Imgix Image Processing

Every Cosmic JS plan comes with the power of Imgix image processing. Imgix makes image processing easy by allowing you to resize, crop, rotate, style, watermark images and more easily on-the-fly. This is especially useful when your app needs to keep image sizes dynamic for optimal rendering speed across devices on desktop, mobile and native apps. Check out the Imgix website to learn more.

Secure Data Storage

Content stored in Cosmic JS and delivered by the API is protected with 256-bit SSL encryption. You can also restrict access to your content by adding optional access tokens located in the Settings tab in your Cosmic JS bucket.

Helpful Resources

Cosmic JS provides excellent resources to help you build your applications. Whatever your programming language preference, you can connect your content to your app through the JavaScript Client (Node.js or in the browser), PHP Client or directly through the REST API. You are also given the option to install and deploy applications through the Settings tab in your Cosmic JS bucket.

Team Friendly

Cosmic JS allows you to add your team members for seamless collaboration. Easily set their role to be either an Admin, Developer or Editor allowing each team member to only see what they need to get their job done.
