Key Points

  • The author describes replacing WordPress, Shopify, and Mailchimp with a Cloudflare Workers-based setup to cut recurring costs (about €176/month plus transaction fees) and reduce hidden operational expenses like updates, backups, and security patching.
  • The new system uses an edge-first architecture: multiple microservices running on Cloudflare Workers, content stored as flat files in Cloudflare R2, caching/config via KV, and real-time behavior via Durable Objects—eliminating databases and origin servers.
  • The post argues that an edge deployment improves latency and performance consistency by routing user requests directly to edge workers and avoiding cache-miss and cold-start scenarios common in traditional CMS stacks.
  • Performance comparisons claim markedly faster time to first byte (~50ms), near-instant full load (~0.3s), and a 100% CWV pass rate for the proposed “AI on Edge” approach versus WordPress and Shopify baselines.
  • The author positions the solution as practical AI-integration on the edge, including AI-generated content, a site-aware assistant with persistent memory, autonomous agent workflows, translation, and automated SEO assets.

How I Replaced WordPress, Shopify, and Mailchimp with Cloudflare Workers

The $300/month problem

As a freelancer, I was paying:

  • WordPress hosting: €20/month
  • Security plugin: €15/month
  • Shopify: €79/month + 2% transaction fees
  • Mailchimp: €50/month
  • Calendly: €12/month
  • Total: ~€176/month + transaction cuts

Plus the hidden costs: updates, backups, security patches, plugin conflicts, slow loading times...

The revelation

What if a CMS didn't need:

  • ❌ A database
  • ❌ An origin server
  • ❌ Plugins
  • ❌ Security patches

What if everything ran on the edge — closer to users than a traditional server could ever be?

Meet AI on Edge

A flat-file CMS built entirely on Cloudflare:

Architecture (no, really — zero servers)

  • 7 microservices on Cloudflare Workers
  • Flat files on Cloudflare R2 (S3-compatible object storage)
  • KV for caching and configuration
  • Durable Objects for real-time features
  • Zero databases. Zero origin servers.

Why this matters

Traditional CMS:

User → CDN → Origin Server → Database → Response
        ↑_________↑
        Cache miss = slow

AI on Edge:

User → Edge Worker → R2 File → Response
        ↑
        Every request is an edge hit

No cache misses. No cold starts. No database queries. Ever.

Performance comparison
