Webflow vs Astro

If designers and marketers will build and change the site themselves, choose Webflow. You design on a canvas, publish with one click, and Webflow handles hosting, SSL and security.

If performance matters to your acquisition, if you want the site in your own repository and on the host of your choice, and if a developer or an agency will maintain it, choose Astro. It is an open-source framework built for content-driven sites, and it sends almost no JavaScript to the browser by default.

Keep in mind that the two are not the same kind of tool. Webflow is a platform with a designer, a CMS and hosting. Astro is the part that builds the pages; the editing interface comes from a headless CMS you add, or from Markdown files in Git.

Webflow is a visual website platform. You design pages in the Designer, which writes clean HTML and CSS as you work, structure content in the CMS, and publish to Webflow’s hosting with one click. Interactions and animations are built visually too, and marketers edit text and publish articles without a developer.

The trade-off is that you work inside Webflow’s model: its hosting, with no choice of region on standard plans, its CMS limits per plan, and custom code or third-party tools for anything the platform does not do. Webflow has its own MCP server and an official Claude connector, and is preparing Source by Webflow, an agentic platform still in limited preview.

Astro is an open-source web framework, under the MIT licence, built for marketing sites, blogs and documentation. Pages are rendered to HTML ahead of time or on the server, and only the interactive parts, which Astro calls islands, load JavaScript in the browser. You can write those islands with React, Vue, Svelte or plain Astro components.

Content can live in Markdown or MDX files, organised in typed content collections, or come from a headless CMS such as Sanity or Payload. An Astro site deploys from Git to Vercel, Netlify, Cloudflare or any static host. Since January 2026 the Astro team is part of Cloudflare, and the framework stays open source and deployable anywhere. The trade-off: there is no visual editor and no built-in admin, so a developer builds the site and someone maintains it.

Nine criteria we look at when a client hesitates between the two. The last column says which one has the edge, from our experience.

This is where most Webflow and Astro comparisons go wrong. Webflow ships with a CMS and an Editor: a marketer logs in, changes a headline, publishes a post. Astro ships with neither.

If the people who write are developers, as on documentation or a technical blog, Markdown or MDX files in Git work very well: content is versioned, reviewed and typed in content collections. If marketers write, you add a headless CMS. Sanity gives a hosted studio with an official MCP server; Payload keeps the content in your own database. Either way, plan that choice from the start, because it shapes the whole project and the budget.

Both produce clean, crawlable HTML, and both give you control over titles, meta descriptions, canonicals and structured data. The difference is what loads after the HTML.

A Webflow page loads Webflow’s script and any interactions you added, plus whatever third-party code the site needs. It is usually fast enough, and a well-built Webflow site scores well. Astro starts from zero: a page ships no JavaScript unless a component needs it, and images are optimised at build time. When Core Web Vitals weigh on your acquisition, or when you publish thousands of pages, Astro gives more margin and fewer things to fight.

Webflow hosts every site on its own infrastructure, built on Amazon Web Services with a global CDN, and you pay a subscription per site that grows with seats, languages and CMS items. Standard plans do not let you choose where the site and the CMS data are stored.

Astro is free. A static Astro site can be served from almost any host, and deploys from Git with a preview URL per branch on Vercel, Netlify or Cloudflare. You pick the region, Europe included, and you pay for hosting and, if you use one, the headless CMS. On a small site the costs are close; the real difference is the build, which takes more development on Astro, and the upkeep, which Webflow takes off your hands.

On Webflow, Claude works through the official MCP connector: it creates and edits CMS items, builds pages and runs bulk changes by conversation, within what the API exposes. You keep the visual control of the Designer and check the result there.

On Astro, the whole site is code in a repository, so an agent such as Claude Code can build a component, add a content collection, fix a layout or write a hundred pages from structured data, then open a pull request that we review before it goes live. That is why Astro, with Next.js, is one of the two frameworks of the open stack we now build on alongside Webflow.

What we recommend, depending on the project in front of us.

Pages and interactions are rebuilt, not imported. The CMS content can be exported, so we treat a migration as a rebuild with the same design and every URL that ranks kept in place.
