If you're evaluating headless CMS platforms and Hygraph is on your shortlist, you've probably noticed the overlap with Cosmic. Both are API-first, both target developers, and both position themselves as modern alternatives to monolithic CMS platforms. But they make meaningfully different bets on what a headless CMS should do in 2026.
This comparison covers pricing, API and SDK, developer experience, AI capabilities, team collaboration, and migration path. Every claim is sourced from public documentation and pricing pages.
The short version
Cosmic is a full-stack AI-native headless CMS with built-in AI Agents, Workflows, an MCP Server, and a JavaScript/TypeScript SDK. It is built for teams that want content infrastructure and AI tooling in one place.
Hygraph is a federated content platform that emphasizes content federation (pulling from multiple sources into one graph) and a schema-first content modeling approach. It is strong for complex enterprise content federation use cases.
The right choice depends on your use case.
Pricing
Cosmic
- Free: $0/month, 1 Bucket, 2 team members, 1,000 Objects
- Builder: $49/month, 2 Buckets, 3 team members, 5,000 Objects
- Team: $299/month, 3 Buckets, 5 team members, 20,000 Objects
- Business: $499/month, 5 Buckets, 10 team members, 50,000 Objects
- Enterprise: Custom pricing
- Additional users: $29/user/month
Hygraph
- Free: $0/month, limited API calls, 2 environments, community support
- Growth: $399/month, more environments, higher API limits, email support
- Scale / Enterprise: custom pricing
Hygraph's paid tiers jump steeply from free to Growth at $399/month, making it expensive for small teams. Cosmic's $49 Builder plan gives you a meaningful production-grade entry point before committing to a higher tier.
API and SDK
Both platforms are API-first. The difference is in the SDK experience.
Cosmic ships an official TypeScript SDK with full type safety, a clean object-oriented interface, and built-in AI text generation. Cosmic's REST API covers all CRUD operations and is straightforward to use without the SDK if you prefer.
Hygraph relies on its REST Content API and a client SDK. Hygraph's heritage is schema/graph-based, which gives it power for complex relational queries but adds setup overhead for teams who want to move fast.
AI capabilities
This is where the platforms diverge most sharply.
Cosmic
- AI Agents: deploy agents in Slack, WhatsApp, and Telegram that can read and write content, run Workflows, and respond to your team conversationally
- AI Workflows: multi-step automated content pipelines (research, draft, SEO review, publish) running on a schedule or triggered by events
- MCP Server: connect any MCP-compatible AI client directly to your content bucket
- AI Text Generation: generate content using Claude, Gemini, GPT, or Kimi K3 models directly from the Cosmic API and dashboard
Hygraph
Hygraph has introduced some AI-assisted content features, primarily around content generation within the editor. It does not offer a native AI Agents layer, conversational Slack/WhatsApp integration, or an MCP Server.
If your team wants to run AI agents as part of your content operation, Cosmic is the only platform in this comparison that ships that natively today.
Developer experience
A few honest differences:
- Onboarding: Cosmic's free tier requires no credit card and gets you to a working API in minutes.
- Content modeling: Hygraph's schema-first modeling is powerful for complex relational structures. Cosmic's object and metafield system is faster to set up and easier for non-technical team members.
- Environments: Hygraph offers multiple environments on paid plans. Cosmic's bucket model gives you isolated content contexts per project.
- Localization: both platforms support localization. Hygraph has deep localization support baked into its schema model. Cosmic supports locale-specific content at the object level.
Team collaboration
Cosmic's AI Agents are built around team collaboration: your marketing team can edit content, trigger Workflows, and query your CMS directly from Slack or WhatsApp, without touching the dashboard. For teams where non-developers need to contribute content without developer bottlenecks, Cosmic's agent layer removes friction in a way that Hygraph's editor-centric model does not replicate.
Hygraph's collaboration is centered on the content editor and role-based permissions within the dashboard, which works well for teams that live in the CMS UI.
Content federation
Hygraph's standout feature is content federation: the ability to define a unified content graph that pulls from multiple third-party sources (Salesforce, commerce platforms, DAMs, etc.) alongside Hygraph-managed content. If your content strategy requires unifying data from many external systems into a single queryable layer, Hygraph's federation model is purpose-built for that.
Cosmic does not offer native content federation. If federation is your primary requirement, Hygraph is the stronger fit.
The honest summary
Choose Hygraph if:
- Content federation across multiple external systems is your primary use case
- You need deep schema-first relational content modeling
- You are on a large enterprise contract that needs Hygraph's federation enterprise tier
Choose Cosmic if:
- You want AI Agents, Workflows, and an MCP Server as part of your CMS, not a separate integration
- You want your marketing team to manage content from Slack or WhatsApp without developer involvement
- You need a production-grade CMS at $49/month before committing to a higher tier
- You are building on Next.js, Astro, Nuxt, or any JavaScript framework and want a TypeScript-first SDK
