How we migrate sites from Webflow to Astro

As Webflow Certified Partners, we know exactly what a Webflow site is made of. Here is our step-by-step process for moving it to Astro without losing content, links or SEO, and how we support you after launch.

We're an official Webflow Certified Partner, and we've been building Webflow sites for many years, ranging from simple startup landing pages to complex enterprise agencies with huge CMSs.

In that time we've seen Webflow sites from every angle: how pages, classes and components are put together, how CMS collections reference one another, and where the SEO settings, redirects and custom code tend to hide.

That knowledge matters most when a site leaves Webflow. A good migration is a careful, one-for-one rebuild that carries across everything your site depends on, so your visitors, your team and search engines barely notice the switch.

If you're still deciding whether to move, our comparison of Webflow vs Astro in 2027 and our explainer on what Astro is and why startups are moving to it are good places to start.

If you've already decided, here is exactly how we do it.

We review your entire website

Every migration starts with a full review of your live site. We use our own agents to work through every page in your sitemap, one by one, to understand how each is structured: its sections and components, the CMS collections it pulls from, its interactions, embeds and any custom code.

From that, we document your whole sitemap. For every page we record:

  • Every internal and external link.
  • Titles, meta descriptions and Open Graph images.
  • Canonical URLs, indexing settings and any other SEO data.
  • Structured data and schema markup.
  • The CMS collections, fields and references behind it.
  • Any custom code and third-party integration used.

This becomes the source (no pun intended) of truth for the rest of the project. Nothing gets rebuilt from memory or quietly dropped along the way.

We rebuild your site in Astro, one-for-one

Next, we rebuild the site in Astro, page for page, using a combination of our expertise, agents and our own internal tool, called etal.

The aim is a site that looks and behaves exactly like the one you have today, but built cleanly underneath.

Webflow concepts map neatly onto Astro when you know both well. Webflow components become Astro components. CMS collections become content collections, with typed schemas that match your existing fields. Your global styles, classes and variables become a tidy set of design tokens.

The result is structured the way you'd expect a professional Astro build to be, so any developer, or any AI agent, can pick it up and understand it straight away.

We export your CMS, redirects and domain

With the site rebuilt, we bring your content across. We do a full export of your Webflow CMS, including every item, field, image and reference, and move it into the new site. Images are downloaded and re-hosted, rather than left pointing at Webflow's CDN. (We've written before about downloading every blog image from the Webflow CMS automatically, and it's the same kind of tooling we use here.)

We also export your 301 redirects so every old URL keeps working, and recreate any forms, scripts and integrations your site relies on.

Then we help you move your custom domain to wherever you plan to host the Astro site, whether that's Netlify, Render, Vercel or Cloudflare. We'll recommend a host if you don't have a preference, and set up the deployment so every change to your code goes live automatically.

We audit the new site against your live site

Before anything goes live, we run our own internal audit, alongside our agents, comparing your live Webflow site with the new Astro version page by page. We check that:

  • Every URL in your sitemap exists on the new site, or redirects correctly.
  • There are no broken internal or external links.
  • Titles, descriptions, canonicals and schema match exactly.
  • CMS content, images and forms all work as they should.

This is the step that protects your search rankings and overall site behaviour.

We launch with as little downtime as possible

Once the audit is clean, we plan the switchover.

Because the new site is already built, tested and deployed on your new host, launch is mostly a matter of pointing your domain at it. We time and sequence the DNS changes so your site is down for as little time as possible, then check everything again once it's live.

We help you leave Webflow (if you want us to)

After launch, we can help you wind down Webflow entirely, from making sure nothing still depends on it to cancelling your site plan and Workspace seats at the right moment. Or, if you'd rather handle that yourself, we'll leave it with you. Either way, you'll keep a full copy of everything we exported.

We show you how to update your site with AI

One of the biggest reasons to move to Astro is how quickly you can change your site with AI tooling. So once you're live, we make sure you can actually do that.

We'll get you set up with tools like Claude Code, etal, or Visual Studio Code if you'd like to jump in and edit code by hand, and walk you through how your site is organised.

You'll learn how to add a page, edit a section or publish new content in minutes, without needing to wait on a developer.

We stay on hand as your site grows

Migration is often just the start. Plenty of teams move to Astro because they want to do more with their site, and we can keep working with you on whatever comes next:

  • Building out new landing pages and sections.
  • Redesigning your site, or parts of it.
  • New interactive experiences, tools and calculators.
  • Third-party integrations you'd rather not set up yourself, such as databases and advanced forms.

All of this is included in our subscription. There are no extra quotes for each new piece of work. If you've worked with us on Webflow design and development before, it works the same way, just with Astro.
