What headless WordPress actually is

In a headless setup, WordPress stays — but only as a content backend. Your visitors see a new frontend built in Next.js, Astro, or Gatsby that pulls content from WordPress through the REST API or WPGraphQL. Searches for this approach are exploding (WPGraphQL interest is up 250% this year), and for some sites it's exactly right.

But notice what didn't change: WordPress is still running. You keep:

  • The hosting bill for a PHP + MySQL server (now in addition to frontend hosting)
  • Plugin updates, core updates, and PHP version migrations
  • The wp-admin login and the entire WordPress attack surface
  • A build pipeline that breaks when the WordPress API changes or the server is down

Headless WordPress is more infrastructure than regular WordPress, not less. You now operate two systems instead of one.

What a full migration is

A full migration removes WordPress entirely. Your content moves into the codebase as Markdown; your design is rebuilt pixel-perfect as components. There is no backend left — no server, no database, no API to keep alive. The whole site is one Git repository deployed to free static hosting.

The honest decision table

Choose headless WordPress when:

  • A non-technical team publishes daily and lives inside the WordPress editor
  • Dozens of editors with roles and workflows depend on wp-admin
  • WordPress plugins handle business logic you can't replace (and you accept the cost)

Choose a full migration when:

  • Your site is content that changes weekly or monthly, not hourly
  • You want the hosting bill and the maintenance burden to be zero
  • You want AI tools to maintain the site — they edit code and Markdown natively, but can't operate wp-admin
  • One to five people touch the content, not fifty

For the marketing sites, blogs, portfolios, and documentation sites we work with, the second list almost always wins. Most teams researching "headless WordPress" don't need a decoupled CMS — they need to not have WordPress anymore.

Cost comparison over three years

Headless: WordPress hosting ($25–60/mo) + frontend hosting + developer time wiring the API + ongoing updates ≈ $1,500–4,000 over three years, plus the original build cost.

Full migration: one fixed fee (from $300) + $0/month hosting + edits done by AI tools or any developer ≈ the migration fee, full stop.

Can I switch later?

Yes, in both directions — but the asymmetry matters. Going static first costs from $300 and you can bolt a Git-based CMS (Decap, Tina) on top later if your editorial needs grow. Building headless first means paying for two systems from day one to hedge a need you may never have.
