How to migrate your website from Webflow to Astro

You've got this beautiful site on Webflow, but you can't really do what you want with it. This year, we've received plenty of requests from clients wanting a way out, mentioning a migration from Webflow to Astro specifically.

With Astro, you can build lightning-fast, modern websites without being tied to a single, expensive platform. Migrating from Webflow to Astro is a strategic business decision that can reduce annual hosting and CMS costs by up to 90% while boosting site performance by over 40%.

We'll walk you through everything you need to know to migrate your website from Webflow to Astro, from a business and a technical perspective.

Why are businesses leaving Webflow?

Webflow is an amazing tool for designers and people who want to get a site up and running quickly without writing code. But as your business grows, you might start to notice some growing pains. The very things that made Webflow attractive at first (its all-in-one nature) can become its biggest drawbacks.

The Webflow vendor lock-in problem

The biggest issue is vendor lock-in. When your entire website, from the design to the hosting to the CMS, is tied to one company, you're at their mercy. They can change their prices, their features, or even go out of business, and you're left scrambling. That's a risky position for any business to be in.

Limited flexibility with Webflow

The modern web is all about flexibility. You might want to use React for one part of your site, Vue for another, and keep the rest static for maximum performance. With Webflow, that's just not possible. You're stuck with their way of doing things.

Astro, however, is built on a "bring your own framework" philosophy. It plays nicely with all the popular technologies, so you're not locked into a single stack. This means you can hire from a wider pool of developers and use the best tool for each job. It's a more resilient and future-proof approach to building your online presence.

What is Astro and why is it so fast?

So, what's this Astro thing all about? Astro is a modern web framework for building faster websites. It's designed for building content-rich websites like blogs, marketing sites, and e-commerce stores. The magic behind Astro is a concept called Islands Architecture.

Imagine your webpage is mostly static content, text and images that don't change. But you have a few interactive elements, like an image carousel or a "buy now" button. Instead of loading a big chunk of JavaScript for the entire page, Astro only loads the tiny bits of JavaScript needed for those interactive "islands." The result? Your pages load incredibly fast, which is great for both user experience and SEO.

Migrating from Webflow to Astro

Moving from Webflow to Astro isn't just a technical task; it's a strategic decision that involves several important considerations. Here's what you need to think about:

Webflow to Astro migration timeline

A successful migration requires careful planning and resource allocation. Here is a typical project plan when working with an experienced agency like ours.

• No CMS needed (a fully static website with no content changes):

  • 5-10 pages

    • 1 month

  • 10-20 pages

    • 2 months

• Headless CMS (possibility to add an unlimited number of pages):

  • 10-15 unique design blocks

    • 2-3 months

  • 20-30 unique design blocks

    • 3-4 months

This timeline assumes you'll use the same design. If you want a redesign, add another month to the timeline. If you also need a rebrand or better messaging, add another month to the timeline.

Exporting your current website code

Webflow allows you to export your site's HTML, CSS, and JavaScript, but there are limitations. You won't get your CMS content, meaning blog posts and other dynamic content need to be manually rebuilt. Forms and site search features will need to be rebuilt as well.

A more professional export process requires a full rebuild and rewriting the code to make sure that you're following the best practices. We only offer this second option whenever we get approached by clients, because it's more stable in the long run to have a high-quality codebase.

Choosing the right hosting

Astro sites are static by default, which opens up a variety of hosting options. Platforms like Vercel, Netlify, and Cloudflare Workers offer free hosting tiers that are perfect for Astro projects. Consider what features you need, such as serverless functions or global CDN, when choosing a host.

Most of our clients' websites are hosted on Cloudflare Workers.

Rebuilding interactive elements

Astro's "Islands Architecture" allows for minimal JavaScript loading, but you'll need to recreate any interactive elements from your Webflow site. This might involve using JavaScript libraries or frameworks like React or Vue to handle client-side interactions.

Handling CMS content

If your site relies heavily on CMS features, consider integrating a headless CMS like Contentful, Sanity, or Statamic. These services provide robust content management capabilities, allowing you to maintain and scale your content more efficiently. We could help you build a page builder with Contentful and Astro, or another Headless CMS of your choice.

Design and style considerations

Your Webflow site's CSS can be imported into Astro, but it's a good opportunity to refactor and clean up styles. Astro's component-based system encourages modular and reusable styles, which can lead to a more maintainable codebase.

We prefer using TailwindCSS, a CSS framework, to make sure that the website is highly modular and efficient. Learn more how to use dynamic components in Astro.

Performance Optimization

Astro is inherently fast, but you can further optimize performance by using image optimization, caching strategies, and lazy loading techniques. Consider using Astro's built-in support for image optimization and other performance-focused features.

Risk Management

Any migration carries risks. Here are some you need to be aware of:

SEO & traffic loss

• Risk: Losing hard-earned search engine rankings due to URL changes or broken links.

• Mitigation: Implement a strict 301 redirect map from old URLs to new ones if you plan to change the URL structure. Our process includes an organized process to make sure there are no broken links.

Business downtime

• Risk: Your website being unavailable during the switchover.

• Mitigation: Make sure to use a staging link for the migrated website. We always use a separate staging link to build and test the new Astro site. The switchover involves a simple DNS update that takes effect almost instantly, resulting in zero downtime.

Broken functionality

• Risk: Forms, integrations, or interactive elements not working on the new site.

• Mitigation: Keep in mind to test everything on the staging server. Our process includes a QA test of all critical user journeys, from form submissions to API integrations.

Astro migration benefits

You could easily achieve top website performance by using a Headless CMS and Astro.

Performance boost

Let's talk about what you'll notice immediately after the migration. First, your site will load noticeably faster. Astro can deliver websites that are 40% faster with 90% less JavaScript compared to traditional React-based frameworks. That's not just a number on a performance test, your visitors will feel the difference. Faster sites mean lower bounce rates, better SEO rankings, and ultimately more conversions.

Think about it this way: every second your page takes to load, you're losing potential customers. Google has shown that as page load time goes from one second to three seconds, the probability of a visitor bouncing increases by 32%. With Astro's performance-first architecture, you're stacking the deck in your favor.

Cheap or no Hosting costs

With Astro, you can deploy your site to platforms like Vercel, Netlify, or Cloudflare Workers, all of which offer generous free tiers. For most small to medium-sized businesses, you'll never need to pay a dime for hosting. Even if you outgrow the free tier, the costs are a fraction of what you'd pay with Webflow.

And because Astro generates static HTML by default, you're not paying for server resources to render pages on the fly. Your site is just a collection of files sitting on a CDN, ready to be served instantly to anyone, anywhere in the world.

Client Success Story

To provide a real-world example, we recently migrated a B2B software company from Webflow to Astro.

• Industry: B2B Software

• Migration Timeline: 9 weeks

Key results after migration:

• 52% faster average page load times (from 4.8s to 2.3s).

• 30% in annual cost savings by moving from a Webflow CMS plan to Cloudflare Workers.

• 13% increase in organic search traffic within 3 months, attributed to improved Core Web Vitals.

Common pitfalls

Of course, no migration is without its challenges. Here are a few common issues you might run into and how to handle them.

Contact forms

Webflow handles forms for you automatically, collecting submissions and even sending email notifications. When you export your code, that functionality disappears. You'll need to set up a form handling service like Formspree, Netlify Forms, or Getform. The good news is that these services are easy to integrate and often have free tiers that are more than sufficient for most sites.

If you want a bit more flexibility, you can always opt-in for Cloudflare Workers and their serverless functions, you can do basically anything from: submitting data to an endpoint, sending emails, etc.

Custom animations

If your Webflow site has a lot of custom animations and interactions, recreating them in Astro will take some work. Webflow's visual animation editor is powerful, and there's no direct equivalent in Astro. You'll need to use JavaScript animation libraries like GSAP or CSS animations to recreate those effects. It's doable, but it requires some coding knowledge.

We prefer using motion.dev for our sites since it provides solid building blocks for building cohesive animations.

Learning curve

If you or your team are used to Webflow's visual editor, switching to a code-first approach can feel difficult, unless you use a CMS with a Page Builder approach. And, you'll have skills that are transferable to any modern web project. You're not just learning Astro; you're learning the fundamentals of modern web development.

Is this migration right for you?

So, should you make the jump? It depends on your situation. If you're a small business with a simple site and you're happy with Webflow, there's no urgent need to migrate. Webflow is a great tool for what it does.

But if any of these sound like you, it's time to seriously consider Astro:

• You need more flexibility and customization than Webflow can provide.

• You want to own your code and not be dependent on a single vendor.

• You're building a content-heavy site where performance is critical.

• You have developers on your team (or you are one) who want more control.

For businesses that are growing and need a more scalable, flexible solution, migrating to Astro is a smart move. Yes, there's an upfront investment of time and effort, but the long-term benefits, in terms of cost savings, performance, and flexibility, are much greater.

Conclusion

Migrating from Webflow to Astro isn't just a change in platforms; it's an upgrade in performance, flexibility, and control. Unlike traditional frameworks that require client-side interactivity for every page, Astro prioritizes delivering content quickly and efficiently. Astro remains our preferred solution for most client projects.
