The main new feature is a decentralized plugin registry built on AT Protocol, letting developers publish plugins without a central marketplace controlling identity or releases; plugins run sandboxed with capability-gated access to content, media, and network resources. Cloudflare migrated its own blog to EmDash as a production stability test. Separately, Cloudflare open-sourced an alpha of EmDash Build, an AI site builder that generates full EmDash sites from a chat prompt. ## Content EmDash 1.0 is out and marked stable. @FredKSchott had been hinting at it, posting "source tells me that EmDash 1.0 is stable. please god." The hope was apparently earned. Cloudflare's announcement describes EmDash as a free, open source CMS built on Astro, and pitches it as a successor to WordPress. It's meant to work with agents as well as people: you can drive it through an API, a CLI, or a built-in MCP server. ## A plugin registry that isn't a walled garden The part I find most interesting is the plugin registry. It's decentralized and built on AT Protocol, so developers can publish plugins without handing their identity or their release ownership to a central marketplace. If you've ever watched a single store operator decide the fate of an ecosystem, you'll see why that matters. Plugins run sandboxed, each in an isolated runtime. Access to content, media, and the network is gated by capabilities, so a plugin only gets what it's explicitly granted. ## Testing it on Cloudflare's own blog Cloudflare migrated its own blog to EmDash as a production test. That's a fair way to shake out problems before calling something 1.0, though one site is hardly the full range of real-world use. ## EmDash Build, an AI site builder in alpha Separately, Cloudflare is open-sourcing an alpha of EmDash Build, an AI site builder. You describe what you want in a chat prompt and it generates a full EmDash site. @itsNoahPham announced it, and @FredKSchott reposted it. It's alpha, so I'd expect rough edges. But pairing a stable CMS with a generator that targets it makes sense, and it fits the agent-friendly angle of the whole release. ## Questions this post answers ### What's new in EmDash 1.0 from Cloudflare?
