What Cosmic does
Cosmic is an AI-powered headless CMS built for teams that move fast. We combine flexible content infrastructure with AI Agents that live in Slack, write content, build features, fix bugs, and deploy apps autonomously. Developers get a REST API with sub-100ms response times, a TypeScript SDK, CLI, and MCP Server that plugs directly into Cursor, Claude Code, and GitHub Copilot. Content teams get an intuitive dashboard with 20+ metafield types, AI image and video generation, and no migrations ever. Teams use Cosmic because it eliminates the need to build and maintain CMS infrastructure while giving them AI capabilities most platforms haven't shipped yet. Used by teams in 150+ countries, 50M+ API requests per month, 99.9% uptime SLA. Forever free plan. No credit card required.
