Learn why you should choose a headless CMS like Cosmic over any other
Cosmic vs. Sanity
Cosmic and Sanity are both API-first headless CMS platforms, but they have taken very different paths in 2026. Sanity focuses on developer customization through its open-source studio and GROQ query language. Cosmic focuses on AI-native content management with three types of AI agents, multi-agent workflows, and the ability to build and deploy entire applications from a single prompt. Here is how they compare across AI features, pricing, developer experience, and more.
AI-Native vs. AI Add-On
Cosmic was built with AI at its core. Every project includes AI agents that can create content, generate images, write and deploy code, browse the web, and communicate with your team through Slack, WhatsApp, and Telegram. These agents run on automated schedules, chain together in multi-step workflows, and operate autonomously with human-in-the-loop review.
Sanity introduced Content Agent in 2025 as an add-on to its existing platform. Content Agent handles bulk edits, content audits, and gap analysis through a conversational interface. It is a useful operations tool, but it does not create new content from scratch, generate images, write code, or integrate with external communication tools.
Developer Experience
Both platforms are API-first and work with any frontend framework including Next.js, React, Astro, and Vue. Sanity uses GROQ, a proprietary query language, and requires developers to configure and deploy Sanity Studio as a separate application. Cosmic uses a standard REST, CLI, Agent Skills, and MCP, with no proprietary query language to learn. The dashboard, media library, and AI tools are all included out of the box.
Build and Deploy with Autopilot
Cosmic Autopilot lets you describe your project in plain language and the platform builds your entire application automatically. It generates your content model, creates demo content, writes frontend code, configures AI agents, and deploys the finished application to production. There is no equivalent feature in Sanity. To launch a new project on Sanity, you need to manually configure your schema, set up Sanity Studio, choose and configure a frontend framework, and deploy everything yourself.

AI-Powered Content Management: Cosmic vs. Sanity
The biggest difference between Cosmic and Sanity in 2026 comes down to AI. Both platforms now offer AI features, but the depth and approach are fundamentally different.
Cosmic: Three AI Agent Types
Cosmic offers three distinct AI agent types that work together to automate your entire content operation:
Content Agents create, edit, and manage content autonomously. Give an agent a topic and it will research, write, generate images, optimize for SEO, and save a draft for your team to review. Schedule agents to run weekly, daily, or on any custom cadence.
Code Agents connect to your GitHub repository and can read your codebase, commit changes, create branches, and open pull requests. Need a new landing page? A code agent can build it, push the code, and deploy it to production.
Computer Use Agents browse the web like a human. They can navigate to pages, click buttons, fill out forms, and take screenshots. Use them for competitive research, automated testing, or monitoring your live site.
Multi-Agent Workflows chain agents together in automated pipelines. For example: a computer use agent scans Hacker News for trending topics, a content agent writes a blog post about the top story, and a code agent commits SEO optimizations. All running on a schedule with zero human intervention.
Team Agents connect to Slack, WhatsApp, and Telegram. Your team can request content, check analytics, or trigger workflows directly from the tools they already use.
Sanity: One Agent Type
Sanity launched Content Agent in 2025. It handles bulk edits, content audits, and gap analysis through a conversational interface. It is useful for operations tasks like updating hundreds of documents at once or auditing your content library.
However, Sanity Content Agent is limited to content operations inside the CMS. It cannot generate new content from scratch, write blog posts, create images, commit code, browse the web, or connect to Slack. There are no code agents, no computer use agents, and no multi-agent workflows.
| Capability | Cosmic | Sanity |
|---|---|---|
| Content creation agents | ✅ | ❌ |
| Code agents (GitHub integration) | ✅ | ❌ |
| Computer use agents (web browsing) | ✅ | ❌ |
| Multi-agent workflows | ✅ | ❌ |
| Team agents (Slack, WhatsApp, Telegram) | ✅ | ❌ |
| AI image generation | ✅ | ❌ |
| Bulk content operations | ✅ | ✅ |
| Content audits | ✅ | ✅ |
| Scheduled automation | ✅ | ❌ |
| Build entire apps from a prompt | ✅ | ❌ |
Pricing: Total Cost of Ownership
Sanity's pricing looks simple at first glance, but costs escalate quickly when you add the features most teams actually need.
Free Tier
Cosmic Free: 2 team members, 1,000 objects, 300K AI tokens (input and output), 100K cached API requests per month. Start for free.
Sanity Free: 20 user seats, 10K documents, 100K API CDN requests per month, 100 AI credits per month. Public datasets only.
Growing Team (5-10 users)
Cosmic Team: $299 per month. Includes 5 team members, 20,000 objects, 1M input and 1M output AI tokens, 25K non-cached API requests, 250K cached API requests, and up to 15 AI agents with scheduling. Add the feature bundle for $199 per month to get webhooks, localization, revision history, and automatic backups at 50% off.
Sanity Growth: $75 to $150 per month (5-10 seats at $15 per seat). But this does not include SSO, dedicated support, or private datasets beyond the included 2. Adding SSO costs $1,399 per month. Dedicated support is $799 per month. Each additional dataset is $999 per month.
Enterprise (20+ users)
Cosmic Business: $499 per month. 10 team members included, with additional seats at $29 per user per month. 50,000 objects, 3M input and 3M output AI tokens, 25 AI agents with scheduling. See full plan details.
Cosmic Enterprise: Custom pricing. Includes branded workspace, single sign-on, 24/7 support, enterprise SLA, and custom usage limits. Get a custom quote.
Sanity Enterprise: Custom pricing. At 20 seats on the Growth plan alone, you are already at $300 per month before any add-ons. With SSO ($1,399), dedicated support ($799), and one extra dataset ($999), the total reaches $3,497 per month or more.
The Hidden Costs
Sanity charges $0.05 per AI credit after your included credits run out. At scale, if your team uses Content Agent frequently, those costs add up with no cap.
Cosmic includes AI tokens in every plan with clear, predictable pricing. Additional tokens are available as token packs starting at $9.50 per million tokens. No surprise bills.
Why Teams Switch from Sanity to Cosmic
Content automation, not just content operations. Sanity Content Agent helps you manage existing content. Cosmic AI Agents create new content, generate images, write code, and publish, all on autopilot.
Predictable pricing. No per-seat fees that scale linearly with your team. No $1,399 per month SSO tax. No $999 per month dataset fees. Compare plans.
Build faster with Autopilot. Describe your project in a sentence and Cosmic builds your entire application: content model, demo content, frontend code, AI agents, and deploys it live. Sanity has no equivalent.
API-first with any frontend. Like Sanity, Cosmic is fully API-first and works with Next.js, React, Astro, Vue, or any framework. But Cosmic also includes built-in AI that works natively with your content, not as a separate product.
Simpler developer experience. One API, one dashboard, one billing relationship. No separate studio to configure, no GROQ query language to learn, no plugin ecosystem to navigate.
