EmDash is a new open-source CMS from Cloudflare
EmDash is a new open-source CMS from Cloudflare. The reason people care is not just that it exists. It is that EmDash combines structured content, an Astro-first frontend, Cloudflare-native deployment, and a plugin model built around explicit capabilities instead of broad default trust.
EmDash is open source and deployable in one click on Cloudflare. It eliminates WordPress plugin security risks through a scoped permission model while retaining familiar features like drafts, revisions, scheduling, full-text search, and live preview.
EmDash combines Astro with a full-stack TypeScript CMS to deliver server-rendered pages, generated TypeScript types, and a polished admin interface. Users get lightning-fast performance and end-to-end type safety without WordPress complexity.
EmDash includes a Model Context Protocol (MCP) server that exposes content, schema, media, taxonomies, and revisions. Users can integrate with Claude, OpenCode, or other MCP-aware tools to automate content workflows that would be manual in other CMSs.
EmDash lets users define content types, collections, fields, and relationships in a seed file. The system generates TypeScript types and handles database migrations automatically on each dev run, eliminating manual schema management.
EmDash supports a plugin ecosystem with secure execution contexts and scoped permissions. Users can add custom block types, admin pages, hooks, and storage integrations without compromising site security.
