Wix & Webflow to Astro Migration — Leave The Closed Platform Without Losing SEO | TestURL.live
Astro Migration Guide

Wix & Webflow to Astro — Leave The Closed Platform, Keep Your Rankings

Agencies are moving clients off Wix and Webflow to Astro for the same reasons: real code ownership, no platform lock-in, no per-item CMS billing, and Lighthouse scores the closed builders can't touch. The risk is the handoff — closed platforms use their own URL structures and widgets, so a careless cutover drops redirects and rankings. This guide covers the export, the URL mapping, and the one step you can't skip: testing the Astro build on your real domain before DNS moves.

Closed Platforms Make Migration Harder — Here's Why

Wix and Webflow are designed to keep you in. That shapes the migration in three ways. Content is locked: Webflow at least exports static HTML and CMS CSV, while Wix offers no clean export — you pull via API, scrape, or rebuild. URLs are platform-shaped: paths like /post/my-slug, /blog-categories/news, or Wix's hashed routes rarely match the clean routes you'll design in Astro, so nearly every URL needs a deliberate 301. Behavior is proprietary: Webflow interactions and Wix Velo code, embedded forms, and CMS lightboxes have no Astro equivalent and must be rebuilt. Get any of these wrong and the failure only appears after DNS has already moved off the platform — which is exactly when it's hardest to roll back.

Migrating Wix/Webflow → Astro, Step By Step

  1. Inventory the live site. Crawl it and export every URL plus its title, meta description, and canonical — your SEO baseline and redirect source-of-truth.
  2. Export what you can. Webflow: static HTML + CMS CSV. Wix: API pull, scrape, or manual rebuild. Reshape into Astro content collections.
  3. Design clean Astro routes and decide trailingSlash — then map each old platform URL to its new path.
  4. Write the 301 redirects in Astro's redirects config or the host's _redirects / vercel.json. Don't forget category/tag bases and the old blog paths.
  5. Rebuild behavior: swap Webflow interactions / Wix Velo for Astro islands or vanilla JS; replace embedded forms with a forms service or SSR endpoint.
  6. Recreate SEO: titles, meta, canonical, OG/Twitter, structured data, @astrojs/sitemap, and robots.txt; set site to your real domain.
  7. Deploy & test on your real domain via TestURL.live before changing DNS — see below.

The Step You Can't Skip: A Real-Domain Test

Because the new host gives you a hostname (not an IP), enter your domain and the platform hostname — my-site.netlify.app, my-site.pages.dev, my-site.vercel.app, or cname.vercel-dns.com — and preview your domain on the Astro host before DNS moves off Wix/Webflow.

Visual Diff

Compare the old Wix/Webflow design against the new Astro pages so nothing shifts on launch day.

Redirect Chain

Confirm every platform URL — /post/..., /blog-categories/... — lands on its new Astro path with a clean 301.

SEO Snapshot

Titles, descriptions, canonical, and H1s checked under your real domain against the pre-migration baseline.

Forms & Console

Test the rebuilt forms and scan for console errors where Webflow interactions or Wix Velo used to run.

Wix/Webflow to Astro — FAQ

Why migrate from Wix or Webflow to Astro?

Full code/content ownership, no lock-in or per-item CMS billing, host-anywhere, and zero-JS-by-default speed the closed builders can't match.

How do I export content from Wix or Webflow?

Webflow exports static HTML and CMS CSV; Wix has no clean export, so you use its API, scrape, or rebuild. Reshape into Astro content collections and plan the URL mapping.

Will I lose SEO making the move?

Only if you skip redirects and meta parity. Map a 301 for every changed URL, recreate the SEO tags and sitemap, then verify on your real domain. See Verify Astro Migration SEO.

How do I test before pointing my domain at Astro?

Deploy, add your domain in the host dashboard, then use TestURL.live with the platform hostname to preview your real domain on the new host.

What breaks most often?

URL/redirect mapping, embedded platform widgets and forms, and Webflow interactions / Wix Velo behavior — all of which you rebuild and re-test.

Is the testing tool free?

The preview and Lighthouse comparison are free; the deeper visual/SEO/security report is on a paid plan or one-time credit.
