What is Cosmic Headless CMS?
Headless CMS is an internet-based implementation of headless software, which enables independence of the data (content) layer from any specific presentation architecture. This modularity in data design and delivery allows for flexibility and portability, future-proofing content against obsolescence of any presentation layer.
It also allows content to be simultaneously integrated with different sources, making content accessible across different website architectures, internet services, and mobile devices. Cosmic Headless CMS additionally offers a robust programmatic and graphical user interface to build and manage headless content.

Intuitive Headless CMS Content Modeling



Powerful APIs
Cosmic provides both a REST and GraphQL API to provide Cosmic-powered data and files to any website or application. Open-source solutions are available to help you get up and running faster. Get started by reading the documentation.
Powerful Rich Text and Media
Adding rich text and media is made simple with the Cosmic HTML content editor. Format text, link to videos from YouTube or Vimeo, upload files and images, embed code from 3rd party services like GitHub, Typeform and more.

Revision History
Mistakes happen. With revision history, you no longer have to worry about editing mistakes. Go back in time and revert your content to a prior version with ease.

Webhooks
Use Cosmic Webhooks to automate workflows and communicate with third-party apps. Webhooks automatically send data to the URL of your choice whenever content is edited in your Cosmic Bucket. This can be used to set up notification workflows in Slack, automatically redeploy static websites to Netlify, as well as a variety of other automation use cases.

Localization
Reach your global audience by publishing multiple versions of your content in different languages. Select from over 400 different locales to serve your content to the world. Retrieving localized content from your Bucket is as easy as adding a locale
parameter to your API request.

Scheduled Publishing
Scheduled publishing is made easy by setting the date and time when you want your draft content set to publish at a later date and time. You can also set published content to unpublish at a later date and time.

Easy Media Management
Along with data and content, Cosmic is your powerful media management solution. Our image API and CDN is the perfect solution for media upload, management, and delivery.
Files uploaded to your Cosmic media area are made available to your Objects via the HTML content editor and File Metafield. Organize media into folders and add metadata for additional organization.

Roles and Permissions
Cosmic allows you to add your team members for seamless collaboration. Easily set their role as an Admin, Developer, Editor or Collaborator allowing each team member to only see what they need to get their job done.
Additional levels of permissions are available to allow management of Bucket Settings and Users for more flexible role delegation.

Search Content
Searching for content shouldn't be hard. You can be sure to find what you're looking for with the search and filter capabilities that comes with every Bucket.
You can then save your filtered content into "Smart Views" that will be added to the sidebar of your Bucket dashboard for easy access. Save for just yourself, or for your whole team.
The same powerful search capabilities are available in the API endpoint. See the changelog announcement for more information.

Content Preview
Cosmic makes it easy to save draft content and preview your changes prior to publishing.
Use the Object Type preview feature (located in Object Type Settings) to easily view draft content in your application prior to publishing.

Single Sign-On
Single Sign-On is a convenient way for large organizations to eliminate large team onboarding hassles and allow for greater control over user access. Cosmic supports Single Sign-On using popular services such as OneLogin, Okta as well as any other Identity Provider that uses the SAML 2.0 protocol.

Data Import / Export
You own your data. Importing and exporting your data is made easy, simply download your Bucket file (in JSON format) and import it into a new Bucket. This makes syncing data between Buckets fast and easy. Copying and pasting Object Schemas (located in advanced settings on the Edit Object page) is also built in for easy duplication across Object Types or Buckets.

Team Workflows
Team user roles are provided to align with your workflow and user access control needs. Restrict content access and automate workflows with webhooks to communicate with your team when content has been changed and ready for editor review.

Extensions
Extend your content editing experience with Extensions. Use them to create custom views in your dashboard and interact with your favorite third-party APIs and services. Check out available Extensions built by the Cosmic team and Community. You can also build your own to customize your dashboard experience.

Activity Logs
Activity logs are available to track team member actions in your projects. See when content was edited, by whom, and view past versions of the content in one high-level view.

Automatic Backups
Your team can work with peace-of-mind knowing that your entire Bucket is backed up every single day. Save a manual snapshot backup intsantly in one click at any time. Download the full backup, import it into another Bucket, or restore the Bucket to the snapshot in one click.

Merge Requests
Merge Requests enables you to do Git-like workflows for content. Move beyond the rigid draft / publish content process into a more fluid, collaborative, and comprehensive workflow.
Perform bulk edits in batches, see update previews, involve team members for review, approvals, and more. Use instant merge rollbacks to revert back to a prior version at any time (automatic backups must be enabled on the target Bucket).
