Every week, someone searches 'WordPress to Astro' or 'website migration service cost.' They have a site that's getting slower, a plugin list that's getting longer, and a hosting bill that's getting harder to justify. They want numbers, not opinions. Here's what WebPulse data shows.
The Scorecard: 45/100 vs. 84/100
WordPress scores 45/100 on the WebPulse framework health index. Astro scores 84/100. That's not a marginal difference — it's the gap between a framework rated 'Caution' and one rated 'Recommended.' Here's how each dimension breaks down:
What Migration Actually Costs
This is the question that matters to budget holders. Migration cost depends on three variables: site complexity, content volume, and whether you need a CMS interface for non-technical editors.
The Hidden Cost of Not Migrating
Migration has a price tag. So does staying. The difference: migration cost is one-time and declining (tools get better). WordPress maintenance cost is recurring and escalating.
Every year you delay, migration costs go up — not because Astro gets more expensive, but because your WordPress site accumulates more technical debt, more custom plugin dependencies, and more content that's harder to extract.
What Actually Happens During Migration
Content. WordPress posts and pages export as structured data (WP REST API or WXR export). Astro's content collections handle Markdown and MDX natively. For most sites, content migration is the easiest part — not the hardest.
URLs. Every URL gets a redirect map. Astro's static routing means your URL structure can match WordPress exactly. No SEO penalty if redirects are set up correctly.
Images and media. Move to Astro's public directory or a CDN. Astro's built-in image optimization (astro:assets) handles responsive images, WebP conversion, and lazy loading — things that required 2-3 WordPress plugins.
Theme and templates. Your WordPress PHP theme becomes Astro components. This is where the developer time goes, but it's also where you gain: cleaner markup, faster rendering, zero plugin dependencies. A typical 10-template WordPress theme converts to 10-15 Astro components.
Forms. WordPress contact forms (Contact Form 7, Gravity Forms, WPForms) are replaced by form services (Formspree, Netlify Forms, Basin) or a simple API endpoint. Most are simpler on the other side.
Search. If you had WordPress search (or a plugin like SearchWP), replace with Pagefind — a static search library that indexes at build time. Zero infrastructure, zero cost.
The WordPress admin panel. For teams that need non-technical editing, pair Astro with a headless CMS (Sanity, Storyblok, Contentful, or Keystatic for Git-based editing). The editing experience is better — live preview, structured content, no plugin conflicts crashing the editor.
The plugin ecosystem. WordPress has 60,000+ plugins. You'll need 0 of them. What plugins provide — SEO, caching, security, image optimization, forms — Astro either handles natively or replaces with a purpose-built service. Each eliminated plugin is one fewer supply chain dependency and one fewer attack surface.
Who Should Not Migrate
Not every WordPress site should move to Astro. If you run WooCommerce with complex e-commerce workflows, Shopify or a dedicated e-commerce platform is a better destination than Astro. If you have a membership site with user authentication, roles, and gated content heavily integrated with WordPress, the migration complexity may not justify the savings for a site with under 100 monthly visitors.
If your site genuinely needs real-time server-side rendering with frequent database writes — not just content delivery — a full-stack framework (Next.js, SvelteKit, Remix) may be more appropriate than static-first Astro, though Astro's SSR mode and server endpoints handle more dynamic use cases than most teams realize.
The Migration Checklist
1. Export content from WordPress (REST API or WXR). 2. Audit plugins — list what each does, find the Astro/service equivalent. 3. Map URLs for redirects. 4. Build Astro components for each template. 5. Set up hosting (Cloudflare Pages, Netlify, Vercel — all have free tiers). 6. Migrate content to Markdown/MDX or connect headless CMS. 7. Configure redirects. 8. Test every URL. 9. Update DNS. 10. Monitor Search Console for 30 days post-migration.
What This Means for Your Organization
The question isn't whether WordPress sites should migrate — our data shows the framework is declining on every dimension except installed base. The question is when. Migrate in Year 1: spend $3,000-$40,000 once, save $85,000-$210,000 over 5 years. Wait until Year 5: spend $40,000-$120,000 after already spending $100,000-$250,000 on maintenance.
Every organization with a WordPress content site should model the migration cost against 3-year and 5-year maintenance projections. For most, the math isn't close.
