Learn why you should choose a headless CMS like Cosmic over any other
Cosmic vs. Strapi
Cosmic | Strapi | |
|---|---|---|
| Technology | API-first platform with REST API. Built-in AI agents for content creation, code generation, and automation. No proprietary query language to learn. | Strapi is built on Node.js with Koa.js and uses a plugin-based architecture. It supports PostgreSQL, MySQL, MariaDB, and SQLite databases. Strapi gives developers full control over the backend and can be extended with custom plugins, middleware, and lifecycle hooks. Cosmic is a fully managed cloud platform built for speed and simplicity. Content is delivered through a global REST API with edge caching. Cosmic's architecture includes three AI agent types that can autonomously create, edit, and deploy content and code. |
| Scalability | Fully managed, globally distributed infrastructure. Scales automatically with no configuration. AI agents scale with your content needs. | Strapi's scalability depends entirely on your hosting infrastructure. Self-hosted Strapi requires you to manage load balancing, database scaling, and CDN configuration. Strapi Cloud handles this but starts at ~$29/month with usage limits. Cosmic is fully managed with automatic scaling, global CDN, and edge caching included on all plans. The Free plan includes 100 Objects and 1GB bandwidth. Paid plans scale to unlimited objects and higher API limits. |
| Security | SSL everywhere. Role-based access control included on all plans. | Strapi provides role-based access control (RBAC), API token authentication, and SSO on enterprise plans. Self-hosted Strapi means you own your security posture: SSL, firewall rules, database encryption, and patching are your responsibility. Strapi Cloud is SOC 2 Type II compliant. Cosmic provides RBAC, API key authentication, and SSO on Business and Enterprise plans. All data is encrypted in transit (SSL/TLS) and at rest. Cosmic is hosted on AWS with automatic security updates. Cosmic is not SOC 2 compliant. |
| CMS maintenance | Fully managed platform. Zero maintenance, zero DevOps. Dashboard, media library, AI agents, and all tools hosted and updated automatically. | Self-hosted Strapi requires ongoing maintenance: server updates, database backups, dependency upgrades, security patches, and Node.js version management. Strapi Cloud reduces this burden but still requires content type migrations and plugin compatibility management during upgrades. Cosmic is fully managed with zero infrastructure maintenance. Updates, backups, scaling, and security patches are handled automatically. There is no server to maintain, no database to manage, and no deployment pipeline to configure. |
| Global caching | Global CDN with edge caching. Automatic cache invalidation on content publish. No configuration required. | Strapi does not include a built-in CDN. Self-hosted deployments require you to configure your own caching layer (Cloudflare, Fastly, etc.). Strapi Cloud includes edge caching on paid plans. Cosmic includes a global CDN powered by AWS CloudFront on all plans. API responses are cached at the edge for fast delivery worldwide. The Cosmic imgix integration provides image optimization and transformation via URL parameters. |
| Media CDN | Built-in imgix media CDN with on-the-fly image optimization, resizing, and transformation. AI image generation included on all plans. | Strapi includes a basic media library with local file storage by default. Cloud storage (AWS S3, Cloudinary) requires additional plugin configuration. Strapi Cloud includes managed media storage. Cosmic includes a built-in media library with imgix integration on all plans. Every uploaded image gets an imgix URL with on-the-fly resizing, cropping, format conversion, and optimization. AI image generation is built into the platform. |
| Image processing | imgix-powered transformations via URL parameters. AI image generation creates original images from text descriptions directly in the CMS. | Strapi relies on third-party services for image processing. You can integrate Cloudinary or Sharp via plugins, but there is no built-in image transformation API. Cosmic includes imgix-powered image processing on all plans. Transform images via URL parameters: resize, crop, adjust quality, convert formats, apply filters, and add watermarks. No plugins or third-party accounts required. |
| Extendability | Webhooks, API integrations, and AI agents that connect to GitHub, Slack, WhatsApp, and Telegram. Multi-agent workflows for custom automation pipelines. | Strapi has a rich plugin ecosystem with 200+ community plugins covering SEO, email, analytics, search, and more. Developers can build custom plugins with full access to Strapi internals. Cosmic extends functionality through three AI agent types rather than traditional plugins. Content Agents automate content creation. Code Agents connect to GitHub and commit code. Team Agents integrate with Slack, WhatsApp, and Telegram for conversational workflows. Cosmic also supports Webhooks and API integrations for connecting to external services. |
| 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. | Strapi is frontend-agnostic and works with any JavaScript framework. It provides REST and GraphQL APIs, starter templates for Next.js, Nuxt, and Gatsby, and detailed integration guides. Cosmic is also frontend-agnostic with a REST API and JavaScript SDK. Cosmic provides starter templates for Next.js, Nuxt, Astro, and other frameworks. The Autopilot feature can generate a complete Next.js frontend from a text description and deploy it to Vercel automatically. |
| Number of projects | Free plan includes 1 project (bucket). Paid plans include 2 to 5 projects with additional projects available as add-ons. | Self-hosted Strapi has no project limits since you control the infrastructure. Strapi Cloud plans range from 1 project (free) to 50+ projects on enterprise. Cosmic's Free plan includes 2 projects. Builder ($29/mo) includes 5 projects. Team ($79/mo) includes 10 projects. Business ($199/mo) includes 25 projects. Enterprise offers custom project limits. Additional team members are $29/user/month on all paid plans. |
| Annual costs | Free forever plan. Paid plans from $49/mo (Builder) to $499/mo (Business). AI tokens included on every plan. | Strapi's open-source version is free to download, but self-hosting costs include server infrastructure ($20-200+/mo), database hosting ($15-100+/mo), CDN ($10-50+/mo), media storage, SSL certificates, and DevOps time. Strapi Cloud starts at free (1 seat, 1 project) and ranges to $99+/mo for teams. Cosmic starts free (2 team members, 2 projects) with paid plans at $29/mo (Builder), $79/mo (Team), $199/mo (Business), and custom Enterprise pricing. All Cosmic plans include hosting, CDN, media library, imgix, and AI features with no infrastructure to manage. |
AI-Powered Content Management: Cosmic vs. Strapi
Strapi is the most popular open-source headless CMS, and for good reason. It gives developers full control over their backend, APIs, and hosting. But in 2026, the CMS landscape has shifted. Teams need more than a content backend. They need a platform that creates content, writes code, and automates workflows. That is where Cosmic and Strapi diverge.
Architecture: Cloud-Native vs. Self-Hosted
Strapi was built as a self-hosted, open-source Node.js application. You download it, configure it, deploy it on your own infrastructure, and maintain it yourself. Strapi Cloud exists as a hosted option starting around $29 per month, but many teams still self-host for full control.
Cosmic is cloud-native from the ground up. There is nothing to install, no servers to manage, no database to configure. Sign up and start building. Your content is delivered through a global CDN with unlimited API requests on every plan.
The trade-off: Strapi gives you more control over your backend infrastructure. Cosmic gives you zero infrastructure overhead and AI capabilities that Strapi does not offer.
AI Capabilities: Four Agent Types vs. Basic AI Features
Strapi added AI Translations in 2025 and has basic AI content assistance through plugins. These are useful for translating content and generating text suggestions within the admin panel.
Cosmic takes a fundamentally different approach with four purpose-built AI agent types:
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 review. Schedule agents to run on any cadence.
Code Agents connect to your GitHub repository. They 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 navigate pages, click buttons, fill out forms, and take screenshots. Use them for competitive research, automated testing, or monitoring.
Team Agents connect to Slack, WhatsApp, and Telegram as conversational AI team members. Your team can request content, trigger workflows, or manage the CMS directly from chat.
Multi-Agent Workflows chain agents together in automated pipelines that run on schedules with zero human intervention.
| Capability | Cosmic | Strapi |
|---|---|---|
| Content creation agents | ✅ | ❌ |
| Code agents (GitHub integration) | ✅ | ❌ |
| Computer use agents (web browsing) | ✅ | ❌ |
| Team agents (Slack, WhatsApp, Telegram) | ✅ | ❌ |
| Multi-agent workflows | ✅ | ❌ |
| AI image generation | ✅ | ❌ |
| AI translations | ✅ | ✅ |
| Build entire apps from a prompt | ✅ | ❌ |
| Scheduled automation | ✅ | ❌ (requires custom code) |
| REST API | ✅ | ✅ |
| Self-hosted option | ❌ | ✅ |
| Open source | ❌ | ✅ |
API: REST-First vs. REST + GraphQL
Strapi generates both REST and GraphQL APIs automatically from your content types. Cosmic provides a REST API with a TypeScript SDK. Cosmic does not offer GraphQL.
For most teams, REST is sufficient and simpler to work with. Cosmic's TypeScript SDK makes integration straightforward with type safety and auto-completion. If your team specifically requires GraphQL, Strapi has that advantage.
Developer Experience
Strapi: Install via npx, configure your database (SQLite, PostgreSQL, MySQL, or MariaDB), define content types through the admin panel or code, customize with plugins and middleware. The developer experience is powerful but requires more setup and ongoing maintenance.
Cosmic: Sign up, create content types, start querying the API. No installation, no database configuration, no server management. Add AI agents that create content and write code for you. The developer experience is simpler but you trade away backend customization.
Pricing: Predictable SaaS vs. Infrastructure Costs
Strapi Self-Hosted: Free and open source. But you pay for hosting (AWS, DigitalOcean, Railway, etc.), database, CDN, backups, SSL, monitoring, and the engineering time to maintain it all. A realistic self-hosted Strapi setup costs $50 to $500+ per month depending on scale, plus engineer time.
Strapi Cloud: Starts at approximately $29 per month for basic hosting. Enterprise pricing is custom.
Cosmic Pricing:
- Free ($0/mo): 1 Bucket, 2 Team members, 1,000 Objects, 3 AI Agents (manual only)
- Builder ($49/mo): 5 Buckets, 3 Team members, 25,000 Objects, 5 AI Agents with scheduling. Additional users $29/user/month.
- Team ($299/mo): 10 Buckets, 5 Team members, 100,000 Objects, 15 AI Agents with scheduling. Additional users $29/user/month.
- Business ($499/mo): 25 Buckets, 10 Team members, 500,000 Objects, 25 AI Agents with scheduling. Additional users $29/user/month.
- Enterprise: Custom pricing with custom team size.
All plans include unlimited API requests. Additional team members beyond the plan's included seats are $29/user/month.
Plugin Ecosystem vs. Built-In Features
Strapi has a marketplace with hundreds of community plugins for SEO, analytics, email, image optimization, and more. This is a strength for teams that want to customize every aspect of their CMS.
Cosmic takes the opposite approach: AI agents, webhooks, localization, revision history, backups, and media management are built in. No plugins to install, maintain, or worry about breaking on upgrade.
SOC 2 Compliance
Strapi advertises SOC 2 Type II compliance for Strapi Cloud. Cosmic is not currently SOC 2 certified. For teams where SOC 2 is a hard requirement, this is a relevant consideration.
Why Teams Choose Cosmic Over Strapi
Zero infrastructure management. No servers, no databases, no DevOps. Cosmic is fully managed.
AI agents that actually work. Not plugins or add-ons. Four types of AI agents that create content, write code, browse the web, and join your Slack channels.
Faster time to value. Describe your project and Cosmic builds your entire application: content model, demo content, frontend code, AI agents, and deploys it live. With Strapi, you are building from scratch.
Transparent pricing. Plans start free with clear tiers. Additional team members are $29/user/month. No surprise infrastructure costs or plugin maintenance overhead.
Works with any frontend. Like Strapi, Cosmic works with Next.js, React, Vue, Astro, Nuxt, and any framework that can make REST API calls.
Why Teams Choose Strapi Over Cosmic
Full backend control. Strapi gives you complete control over your server, database, and API logic. If you need custom middleware, database queries, or server-side logic, Strapi is more flexible.
