How much does it cost to migrate a WordPress site to Astro?

The realistic 2026 range runs from USD 3,000 to USD 35,000 depending on scope. A small marketing site (under 30 pages, no complex integrations, no advanced form logic) usually costs between USD 3,000 and USD 6,000. A mid-size site with 30 to 150 pages, integrated forms, 301 redirects, and structured QA lands between USD 6,000 and USD 15,000. An enterprise site with more than 150 pages, multiple integrations (HubSpot, Mailchimp, CRMs), bulk redirects, and cross-browser testing can reach USD 15,000–35,000. If someone offers you "USD 500 for a complete migration", the scope likely excludes redirects, QA, forms with a backend, or transition SEO strategy — and that turns the migration into a net risk.

How long does a real migration take?

A small, well-scoped site can be migrated in 2 to 4 weeks. A mid-size site needs 6 to 10 weeks once you account for discovery, design/refactor, content migration, 301 redirects, QA, staged deploy, and post-launch monitoring. An enterprise site can take 3 to 6 months including integrations, team training, and coexistence with the current WordPress during the transition. The migrations that finish "in a weekend" are personal blogs without integrations, not business sites — confusing the two is the most expensive mistake.

What happens to SEO when you migrate from WordPress to Astro?

Done well, the migration improves SEO: Astro typically scores 100 on Lighthouse SEO versus an average of 86 on WordPress, and Core Web Vitals improve substantially (LCP, INP, and CLS), signals Google uses for ranking. The risk is in the transition: without a 301 redirect map from every old URL to the new one, without preserving metadata (title, meta description, canonical, hreflang), without migrating the sitemap.xml structure, and without notifying Google Search Console of the change, a migration can lose 30–60% of organic traffic for 4–8 weeks until it recovers. The redirect plan and the pre-migration SEO audit are what separate a net improvement from a temporary disaster.

Will my team be able to edit content like in WordPress after migrating?

Not the same way, but there are middle-ground options. Native Astro edits content in Markdown files under version control (Git), which requires basic technical knowledge. For non-technical teams there are three paths: (1) Keystatic or Decap CMS — visual interfaces on top of Astro that write Markdown to Git transparently; the editor publishes from a dashboard without touching code; (2) headless WordPress + Astro — the team keeps editing in WordPress as before, and Astro consumes the content via REST/GraphQL; preserves the editorial experience but doubles the infrastructure; (3) Sanity, Contentful, or Storyblok — third-party headless CMS, higher monthly cost but a polished editorial experience. The choice depends on editing volume and operational budget.

What do I lose by migrating from WordPress to Astro?

You lose access to the massive WordPress plugin ecosystem: if your site depends on Gravity Forms with complex conditional logic, MemberPress for a members area, LearnDash for online courses, BuddyBoss for community, or WooCommerce with specific extensions, those components don't have a direct Astro equivalent and rebuilding them can turn the migration into a custom development project. You also lose the "everything in one dashboard" editing — although Keystatic and Decap mitigate part of this, they don't replicate Gutenberg's depth with custom blocks. If those components are critical to your operation, the honest answer is don't migrate — at least not yet. What you gain: performance, security by architecture, hosting costs near zero, and a site that doesn't require weekly security maintenance.

Migrate WordPress to Astro: when it makes sense (and when it doesn't)

If you got this far, it’s because your WordPress is starting to cost more than it returns: hosting went up, critical plugins raise their prices every renewal, the site loads slow, and every update has the team holding their breath. Migrating WordPress to Astro sounds like the obvious solution and the benchmarks back it up. But the decision is rarely as clean as the “how I migrated my blog in a weekend” testimonials suggest. This guide tries something most don’t: be honest about when migrating makes sense and when it doesn’t, with real USD costs and actionable criteria.

What real problem does Astro solve that WordPress doesn’t?

Astro generates static HTML with a minimal sprinkle of JavaScript hydrated only where it’s needed. That turns the site into flat files served from a CDN, with no PHP and no database in production. For a marketing site or a corporate blog, that architecture changes three variables at the root: performance, attack surface, and operating cost over 12 months.

Measurable performance: Lighthouse, LCP, and JS/CSS reduction

Public benchmarks from real migrations agree on similar orders of magnitude: LCP of 0.4–0.6 s on Astro versus 0.8–1.5 s on a well-optimized WordPress, a 60–90% reduction in JS and CSS shipped to the browser, and Lighthouse SEO of 100 versus an average of 86 on WordPress. The official definitions of each metric live at web.dev/articles/vitals; the point is that the improvement doesn’t come from “tuning” but from eliminating work: the browser no longer downloads 1.2 MB of plugin JS or waits for the backend to render.

Before deciding to migrate, check whether your performance issues are solvable on WordPress — how to diagnose Core Web Vitals on WordPress — because sometimes what’s missing is properly configured caching, not a migration.

Security by architecture: no PHP in production

WordPress accounts for 96% of known CMS hacks, almost always through outdated or exposed plugins. Astro eliminates that whole category: there’s no PHP running, no database accessible from the web, no /wp-admin panel to scan. The attack surface shrinks to the CDN and the code repository. That doesn’t mean “magically secure”; it means the threats change type: you go from watching plugins to watching npm dependencies and deploy secrets.

Hosting and maintenance costs over 12 months

Honest business-grade WordPress hosting costs USD 30–150/month; once you add premium plugins (forms, security, backups, cache), licenses, and technical maintenance, an SMB pays between USD 1,500 and USD 5,000/year. Astro deployed on Vercel, Netlify, or Cloudflare Pages typically runs on the free tier or USD 20/month even with decent traffic. Astro removes several maintenance categories covered in the WordPress maintenance guide for businesses: no plugin updates breaking the site every quarter, no urgent security patches, no PHP incompatibilities.

Comparison table: WordPress vs. Astro

Axis	WordPress	Astro
Performance (TTFB)	800–1,500 ms uncached; 200–400 ms with aggressive, well-configured cache	< 100 ms steady from a global CDN edge
Security	Wide surface: PHP, MySQL, plugins (96% of CMS hacks); requires weekly patches	No runtime in production; surface limited to CDN and build pipeline
Maintenance	4–8 hours/month on updates, monitoring, verified backups	< 1 hour/month — only repo dependencies when publishing
Editing	Visual Gutenberg; any editor can publish without code	Markdown + native Git; with Keystatic or Decap you get a visual UI on top of Git
Cost over 12 months (real SMB)	USD 1,500–5,000/year (hosting + premium plugins + maintenance)	USD 0–500/year (CDN hosting + domains + a couple of SaaS services)

The table hides an important nuance: these advantages assume your case fits Astro. If it doesn’t, the math flips.

When NOT to migrate (be honest before you get excited)

This is the section the rest of the SERP skips. The cases below aren’t rare: they’re the majority of the business WordPress market. If your site falls into any of them, migrating is probably the wrong call in 2026.

You run an active WooCommerce store with more than 50 SKUs

WooCommerce with a real catalog, integrated payment gateways, and configured shipping methods doesn’t get “migrated to Astro”: it gets rebuilt. The technical option exists (headless WooCommerce consumed by Astro, or a swap to Shopify, Snipcart, or Medusa), but the operating cost of a headless commerce setup beats a well-hosted, direct WooCommerce. Maintaining two infrastructures (WordPress as product backend + Astro as frontend), syncing inventory, managing order webhooks, and replicating specific extensions (subscriptions, variable products, multi-currency) turns the migration into a multi-month project with doubled bug surface. If you sell online with WooCommerce and it works, don’t migrate yet.

Your team is non-technical and edits content weekly

Native Astro edits Markdown under Git. Although Keystatic and Decap CMS provide a visual UI on top of Astro, neither replicates the fluidity of Gutenberg with custom blocks, integrated media library, and instant preview. If your marketing team publishes weekly posts, uploads images from mobile, schedules with an editorial calendar inside the CMS, and rotates contributors every quarter, the operating cost of switching paradigms goes straight to the editor — and that doesn’t show up in the migration budget but does show up in first-year productivity.

You depend on critical plugins with no native equivalent

Gravity Forms with advanced conditional logic, MemberPress with membership tiers and content dripping, LearnDash with courses and certifications, BuddyBoss with community and messaging, visual builders like Elementor Pro or Divi with global templates: none of these have a plug-and-play Astro equivalent. Rebuilding them is custom development, which typically turns a “USD 8,000 migration” into a USD 25,000+ project. If those plugins are the heart of the product, the honest answer is to wait — or to budget for reality.

Your site has fewer than 10 static pages

Migration ROI scales with the pain you avoid: hosting, premium plugins, attacks. For a 5–10 page site on USD 15/month hosting that doesn’t get attacked or fall over, the math doesn’t add up. The migration would cost USD 2,000–4,000 that take years to amortize, while the team absorbs the operational cost of the change. Stay on WordPress and spend the budget on something with measurable return.

When you SHOULD migrate

The ideal Astro migration profile: a marketing or institutional site under 200 pages that’s mostly static, a corporate blog focused on SEO and speed, campaign landing pages, portfolios, technical documentation sites, and cases where the team already has Git culture (engineering, technical agencies, SaaS). In those contexts, the advantages of Astro (performance, security, cost) translate directly into business metrics without sacrificing capabilities your operation actually uses.

One additional clear signal: if your WordPress takes a hit from updates that break the site every quarter, if you pay more than USD 100/month in premium plugins you barely use, or if Lighthouse scores below 60 even after optimizing cache and CDN, migrating stops being optional and becomes technical hygiene.

The 3 migration strategies (with real tradeoffs)

There isn’t a single way to migrate WordPress to Astro. There are three strategies and each one solves a different case. Choosing wrong here is the mistake that costs the most to fix later.

Full rewrite to Astro with content in Markdown. The site is rebuilt from scratch in Astro, content is exported from WordPress and converted to Markdown in the repository (with or without Keystatic on top). Maximum performance, minimum operating cost going forward, technical editing. Typical ranges: USD 3,000–6,000 for 10–30 pages, USD 6,000–15,000 for 30–150 pages, USD 15,000–25,000 for 150+ pages with bulk redirects and cross-browser QA.
Headless WordPress + Astro. WordPress stays as CMS (the team edits the same as before), Astro consumes the content via REST API or GraphQL (official guide). Preserves the editorial experience but doubles the infrastructure: you pay WordPress hosting + Astro hosting and maintain both stacks. Useful when the problem is only the public layer (performance) and the team can’t leave Gutenberg. Ranges: USD 6,000–10,000 for 30 pages, USD 12,000–25,000 for 150 pages with complex syncing.
Hybrid: Astro front + WordPress for blog only. The main site is rebuilt in Astro with content in Markdown, and the WordPress blog stays at /blog as a subdomain or subfolder. Solves “the blog is the editorial bottleneck but not the home page performance problem”. Ranges: USD 4,000–8,000 for small sites, USD 8,000–18,000 for mid-size. Cheaper than full headless but requires discipline with technical SEO (canonical, unified sitemap).

An Astro migration is a typical fixed-scope project — if you don’t have an internal technical team to lead it, consider our guide to outsource software development in LatAm before hiring the first freelancer who offers you “USD 800 for everything”.

Can your team operate Astro? (and when do you need a technical partner)

Operating Astro post-migration requires three minimum skills: Markdown to write content, basic Git to version (commit, push, pull), and handling the deploy platform (typically Vercel, Netlify, or Cloudflare Pages). If the marketing team has never touched Git, you need a visual layer on top — Keystatic or Decap CMS are the most battle-tested options, and they let editors publish from a dashboard that writes Markdown to Git transparently. Sanity, Contentful, or Storyblok are third-party headless alternatives with a more polished editorial experience but a higher monthly cost (USD 99–500/month depending on tier).

The signals that you need a technical partner for the migration are specific: integrations with CRMs (HubSpot, Salesforce, Pipedrive), forms with backends (sending to Mailchimp, conditional logic, webhooks), multilingual sites with WordPress multisite or WPML, 301 redirects across 50+ URLs, or when the site moves revenue that justifies structured QA instead of “ship it and see what happens”. If your case stacks two or more of those signals, hiring someone with prior experience in real migrations keeps the projected savings from evaporating in post-launch bugs.
