Why teams move to Cosmic
Cosmic turns your pages into structured, API-first content you can build on with any framework, and grow with AI, without the overhead of a legacy CMS.
API-first content
Deliver content anywhere through a fast REST API with TypeScript SDKs.
AI built in
Generate, translate, and optimize content with AI agents that work inside your CMS.
No lock-in
Structured, portable content you own, not trapped inside a theme or template.
Nothing to maintain
No servers, plugins, or security patches. Cosmic is fully managed and always up to date.
Fast and scalable
A global CDN and media pipeline serve your content and images at any scale.
Reuse everywhere
Model content once and reuse it across web, mobile, and every channel you ship.
Leave your legacy CMS behind
Plugin bloat and never-ending security updates
Slow, monolithic themes glued to your content
Content locked into one framework or template
Expensive hosting, backups, and maintenance
Hard to reuse content across web and mobile
Painful version upgrades and risky migrations
What you get with Cosmic
Structured content with a clean, versioned model
A managed platform, no servers or plugins to run
AI agents for content generation and workflows
Predictable pricing that scales with your team
One content source for web, mobile, and apps

The improvement has been substantial. With our previous system, content updates typically took 1-2 weeks to move through development and deployment. With Cosmic, we publish updates in real-time.

Just tried Cosmic for the first time I can say it is hands down the best experience I’ve had with a CMS. I was up and running an Astro site within 10 minutes 💫 I have the urge to tell everyone I know.
