Developer and Designer Experience

Astro

Astro is built for developers who want complete control. You write standard HTML, CSS, and JavaScript with modern tooling -- TypeScript, Tailwind CSS, component frameworks, and the full npm ecosystem at your disposal.

Version control with Git means you can track every change, collaborate through pull requests, and roll back instantly. There is no proprietary editor -- you use VS Code or any text editor you prefer.

Webflow

Webflow is built for designers who think visually. Its canvas-based editor lets you build responsive layouts, add interactions, and manage content without writing code. The learning curve is steep for beginners, but experienced designers find it powerful.

The built-in CMS allows content teams to update text and media through a structured interface. However, you are limited to what Webflow supports -- custom server-side logic, complex APIs, or non-standard functionality requires workarounds or external tools.

Pricing

Astro

Astro is free and open source. Host a static site on Cloudflare Pages, Netlify, or GitHub Pages at no cost. Even high-traffic sites rarely exceed free-tier limits because static files are cheap to serve.

Your primary cost is development time. Once built, the site essentially runs for free with no recurring platform fees.

Webflow

Webflow site plans range from $14/month (basic) to $39/month (business). The CMS plan at $23/month adds dynamic content collections. E-commerce plans start at $29/month. Workspace plans for teams start at $28/month per seat.

Costs add up with multiple sites and team members. Over 3 years, a single Webflow CMS site costs roughly $830+ in platform fees alone, compared to $0-45 for Astro on a free host.

Our Verdict

Webflow is a powerful visual builder that lets designers create professional websites without writing code. It is particularly strong for teams where designers lead the web development process and need to iterate on layouts and interactions visually.

Astro wins on performance, flexibility, and long-term cost. Because you write standard code and own every file, there is no vendor lock-in and no monthly platform fee. You can deploy anywhere, integrate any tool, and build exactly what you need without platform constraints.

For businesses investing in a website that needs to perform at the highest level, scale without escalating costs, and remain fully under your control, Astro is the stronger foundation. If your team works visually and does not have developers, Webflow is a practical alternative.
