Learn why you should choose a headless CMS like Cosmic over any other
Cosmic vs. Adobe Experience Manager
Cosmic | Adobe Experience Manager | |
|---|---|---|
| Technology | API-first platform with REST API. Built-in AI agents for content creation, code generation, and automation. No proprietary query language to learn. | Java, Apache. Database options: MongoDB, Oracle Database, Microsoft SQL Server. |
| Scalability | Fully managed, globally distributed infrastructure. Scales automatically with no configuration. AI agents scale with your content needs. | Does not scale easily. Limited by servers. |
| Security | SSL everywhere. Role-based access control included on all plans. | You maintain the security yourself. |
| CMS maintenance | Fully managed platform. Zero maintenance, zero DevOps. Dashboard, media library, AI agents, and all tools hosted and updated automatically. | They deploy, host, and maintain everything for you. Along with your application and content, you need to maintain updates and security for your CMS system. |
| Global caching | Global CDN with edge caching. Automatic cache invalidation on content publish. No configuration required. | No caching included out of the box. |
| Media CDN | Built-in imgix media CDN with on-the-fly image optimization, resizing, and transformation. AI image generation included on all plans. | No CDN included out of the box. |
| Image processing | imgix-powered transformations via URL parameters. AI image generation creates original images from text descriptions directly in the CMS. | Manually manage your own image sizes and optimizations. |
| Extendability | Webhooks, API integrations, and AI agents that connect to GitHub, Slack, WhatsApp, and Telegram. Multi-agent workflows for custom automation pipelines. | Possible. Limited. Complicated. |
| Frontend | Works with any frontend framework. Official templates for Next.js, React, Astro, Vue, and more. Autopilot builds and deploys complete applications from a prompt. | Front end is coupled with backend CMS. Can be made to be Headless. |
| Number of projects | Free plan includes 1 project (bucket). Paid plans include 2 to 5 projects with additional projects available as add-ons. | One login, one website. |
| Annual costs | Free forever plan. Paid plans from $49/mo (Builder) to $499/mo (Business). AI tokens included on every plan. | You will need to hire developer resources as this system is WAY complicated and outdated. Average salary of a full-stack developer is $111,600 per year. You may need to hire 1-3 developers to maintain the CMS. Plus the cost of licensing Adobe Experience Manager (AEM) can be astronomical. |
Why Teams Replace Adobe Experience Manager with Cosmic
Adobe Experience Manager (AEM) is the dominant platform for global enterprise digital experience management. Its deep integration with the Adobe ecosystem (Analytics, Target, Campaign, Marketo), robust DAM, and mature personalization capabilities make it the CMS of choice for the Fortune 500 companies that can afford it.
But AEM is not for most teams. It is Java-based, requires specialist developers, and has a total cost of ownership that typically starts at $500,000 per year before implementation. In 2026, Cosmic offers a genuinely different path: AI-native content infrastructure with zero server overhead and a REST API that any frontend developer can use.
What AEM Does Well
- Deep integration with Adobe Marketing Cloud (Analytics, Target, Campaign)
- Enterprise-grade DAM for managing millions of assets
- Powerful multi-site and multi-language management at global scale
- Advanced personalization and A/B testing natively integrated
- Long track record with regulated industries and global enterprises
Where AEM Falls Short for Modern Teams
Extraordinary total cost of ownership. AEM licensing typically starts at $250,000+ per year. Add Java developer salaries, implementation partners, hosting infrastructure, and ongoing maintenance, and TCO easily exceeds $500,000 to $1M+ annually. This is not a platform for teams without an enterprise budget.
Java in a JavaScript world. AEM is built on Java and Apache Sling. Most modern frontend developers work in TypeScript, React, and Node.js. Using AEM as a true headless backend requires additional integration work and specialized developer expertise.
No AI agents. Adobe has added AI features (Adobe Sensei, GenStudio) for content generation and asset tagging. But AEM has no autonomous AI agents that create content on a schedule, write code, open pull requests, or run multi-step automated workflows without human intervention.
Months to implement. An AEM implementation typically requires a dedicated team of developers and a 6 to 18 month implementation timeline before you publish live content.
Cosmic's Approach
Cosmic delivers what modern developer and content teams actually need:
- A REST API and TypeScript SDK that any JavaScript developer can use on day one
- AI agents that create content, write code, and run workflows without human intervention
- Zero server infrastructure, zero Java, zero implementation partners required
- Launch in days, not months
Cosmic's AI platform runs on Claude. Build and deploy full applications from a single prompt.
