AI-Driven Migration: WordPress to Gatsby on AWS Amplify in Minutes, Not Days

How Claude Code transformed a complex WordPress-to-Gatsby migration from a days-long project into a matter of minutes. A detailed account of an AI-assisted migration that achieved 94% cost reduction and dramatically improved performance.

After running joe0.com on WordPress for more than two decades, I finally made the jump to a modern static site generator. What I thought would take days turned into just 30 minutes, thanks to Claude Code. The result? Faster site, lower costs, and far less stress.


🎯 Key Outcomes

Metric Before After Improvement
Time 18 hours 30 minutes 97% faster
Cost $300/year $18/year 94% cheaper
Performance 3–5s load times <1s load time Huge speed boost
Quality 5.9/10 “meh” 9.4/10 “slick” +59% improvement

Think of it like swapping your old beat-up commuter car for a Tesla overnight—same website, completely different experience.


Why I Left WordPress

WordPress did the job for years, but it aged like milk in the sun:

  • Performance drag: Every page request meant database queries and PHP juggling.
  • Security headaches: New plugin, new vulnerability.
  • Maintenance hell: Updates broke things more often than they fixed them.
  • Cost creep: Hosting + SSL + premium plugins added up fast.

Static sites with Gatsby solved all of these at once: blazingly fast, inherently secure, and practically free to host.


🚧 The ServerlessWP Detour

I first tried migrating with ServerlessWP, hoping to keep WordPress but make it “serverless.” Cool idea… until reality hit:

  • Cold starts: Lambda functions meant 10–15s load times (users thought the site was broken).
  • Plugins broke: Many rely on file systems or PHP quirks that don’t exist in Lambda.
  • Costs weren’t lower: Between RDS minimums and CloudFront traffic, it actually cost more than my VPS.
  • Debugging was painful: When the admin dashboard went down after a plugin update, I basically had to play sysadmin in the dark.

Lesson learned: sometimes a clean break (WordPress → Gatsby) beats duct-taping old tech.


🤖 Enter Claude Code

Claude Code changed everything. In one conversation it:

  1. Pointed out why ServerlessWP was a dead end.
  2. Recommended Gatsby.js + AWS Amplify.
  3. Generated the configs, component architecture, and DNS fixes.
  4. Solved tricky issues (like dark mode CSS conflicts and SPA routing) in minutes.

Instead of days of trial-and-error, I had:

  • Content exported and converted to Markdown.
  • A Gatsby site with pagination, category pages, and client-side search.
  • A proper dark/light theme system (no more white boxes at midnight).
  • GitHub → Amplify auto-deploy pipeline with SSL and CDN baked in.

⚡ Results

Area Before After Gain
Performance 3–5s load times Sub-1s load times 🚀
Reliability Dependent on VPS/DB Static files, no downtime
Costs $25/month ($300/year) ~$1.50/month ($18/year) 💰
Workflow Manual updates, plugins Git push → auto deploy 🔄

Basically: more speed, less stress, and my wallet finally gets a break.


📚 Lessons Learned

  1. Don’t force old tech into serverless—WordPress isn’t built for it.
  2. Always account for hidden costs (time, debugging, gray hairs).
  3. Strong ecosystems matter—Gatsby’s is thriving, ServerlessWP’s was tumbleweeds.
  4. Automate early—CI/CD saves headaches later.
  5. Even failed experiments are valuable—document them for future you.

🚀 Bigger Picture

This wasn’t just a migration; it was proof of how AI is reshaping development. Claude Code wasn’t just “helpful”—it felt like pair programming with a senior dev who never sleeps:

  • Instant stack expertise.
  • Best-practice code generated in minutes.
  • Debugging that feels like cheating (but hey, I’ll take it).

✅ Conclusion

Migrating from WordPress to Gatsby on AWS Amplify would normally take days of work and a chunk of cash. With AI, it was a 30-minute sprint that delivered:

  • 94% cost savings
  • Sub-second load times
  • Simpler, more reliable architecture

The big takeaway? AI isn’t optional anymore—it’s your new dev partner.
