Do you trust that moving to proprietary custom software provides better reliability than established platforms?
Cloudflare has officially migrated its primary blog from WordPress to EmDash, an open source content management system developed in-house. The platform is designed to handle significantly higher traffic loads than the previous system.
Why it matters
The transition addresses performance limitations and periodic latency spikes observed on the previous platform. By shifting to a system built on Cloudflare Workers, the team aims to better manage high-demand traffic periods.
The new infrastructure supports 7,000 requests per second, far exceeding typical blog traffic of 75 requests per second and known spikes of 5,000 requests per second. The system utilizes Cloudflare Workers with multiple caching layers and an added Model Context Protocol server.
The players
Cloudflare
A global provider of content delivery network services, security, and edge computing solutions that operates a large distributed server network.
The details
Cloudflare executed the migration by deploying a proxy Worker—a script that intercepts and handles network requests at the edge—to gradually route traffic from the legacy WordPress site to EmDash. The team used a version cookie on incoming requests to toggle between the old and new site experiences during a phased rollout. The new architecture integrates an MCP server, which provides a standard interface for content management and allows AI agents to interact directly with the blog data.
Timeline
April 2026: Cloudflare introduced the v0.1.0 developer preview of EmDash.
September 2026: The company migrated its main blog to the EmDash platform.
The Tech Race
This migration positions EmDash as a specialized alternative to traditional WordPress deployments within the Cloudflare Workers ecosystem. It represents a shift toward building content platforms that leverage edge-native architecture rather than conventional server-side frameworks.
Readers accessing the Cloudflare blog should experience improved site stability and reduced latency during high-traffic events. The underlying technology relies on the company's edge computing stack, meaning no hardware or software changes are required for site visitors.
The takeaway
The move marks a departure from general-purpose CMS platforms toward highly customized edge-native solutions for technical content. Watch for the forthcoming v1 release of EmDash, which will signal the platform's readiness for wider adoption beyond internal use.
