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.
