Extend with plugins
Add your own block types, admin pages, hooks, storage, and API routes in TypeScript. Every section on this page is a block from this site’s own plugin.
{ type: "marketing.capabilities", label: "Capabilities", description: "Feature bento with illustrations", // Only the header is editable. Card copy lives in Capabilities.astro, // next to the illustration it describes. fields: [ {Plugins without the security nightmare
Plugins you install from the admin run in their own isolated sandbox. They see no environment variables or filesystem, and get only the capabilities they declare and you approve.

Frequently asked questions
What is EmDash?
EmDash is an open source CMS built on Astro from Cloudflare. It gives you a typed schema, a polished admin, and an MCP server so both humans and AI agents can manage your content.
How is it different from other CMSs like WordPress?
EmDash is a fully typescript full-stack CMS built on Astro. It has a lot of similarities to popular CMSs like WordPress, but improves on its security posture by eliminating the risk that comes with its plugin ecosystem. EmDash will support a new plugin ecosystem based on secure execution context and scoped permissions, making sure your plugins can't damage your site.
Do I need to use AI to use EmDash?
No! EmDash is a great CMS whether you run it with AI agents or not. Where EmDash excels is in shipping a Model Context Protocol server that exposes content, schema, media, taxonomies, menus, and revisions. Drop it into Claude, OpenCode, or any MCP-aware tool and it just works. Suddenly things that were a chore in other CMSs can be sent off as work for your agent to do.
How do I get started?
Open the playground for an instant sandbox, or run npm create emdash to scaffold out a new project on your local computer ready for deployment.
