Astro vs Nuxt: which should you choose?
Both are excellent, but they optimise for different jobs. Astro is built for content-driven sites that should ship almost no JavaScript and can mix any UI framework; Nuxt is the Vue meta-framework for building Vue applications and full-stack sites. Here's the honest split — and why the framework you pick doesn't have to dictate how you build and ship it.
Pick by what you're actually building:
- Content-driven site (blog, docs, marketing) → Astro — zero-JS islands, best Core Web Vitals.
- Vue app or full-stack site (server routes, auth, data) → Nuxt — Vue everywhere, Nitro server, rich module ecosystem.
- Mostly content with a bit of Vue → Astro with Vue islands — you may not need Nuxt.
- Build & deploy either, on any host → Buddy — own the build, choose the host.
The honest split
Where each one wins
Choose Astro when…
- The site is content-first: blog, docs, marketing, a portfolio or a content-heavy storefront.
- You want zero client JavaScript by default and only hydrate the interactive islands you mark.
- You like mixing UI frameworks — Vue, React, Svelte, Solid — or plain
.astrocomponents, and only need Vue in a few islands. - Top Lighthouse / Core Web Vitals scores out of the box matter more than app-grade full-stack machinery.
Choose Nuxt when…
- Your team is all-in on Vue and you're building a Vue application, not just static content.
- You need full-stack features: the Nitro server engine, server routes and API endpoints, auth and dynamic data.
- You want the rich Vue/Nuxt module ecosystem, auto-imports and end-to-end Vue DX across the whole app.
- Server-rendered, data-driven Vue routes at scale are the core of the product, not an add-on.
Side by side
Astro vs Nuxt, compared
Both are free and open-source (MIT). The difference is philosophy: HTML-first with optional islands (any UI framework) vs a Vue-first full-stack framework.

Where Buddy fits
Own the build, choose the host
Buddy is one way to do this — GitHub Actions, GitLab CI and Bitbucket Pipelines can build these frameworks too. The point is that your build and host stay a choice you own, independent of the framework.
The Astro-vs-Nuxt decision is about the framework. How you build and where you deploy is a separate choice — and one you shouldn't have to redo if you change your mind. Buddy builds either framework and ships it anywhere.
Builds both
A Node.js build step compiles either an Astro or a Nuxt project — same pipeline model, no lock-in to one framework.
Deploy anywhere
Ship to Cloudflare, Netlify, Vercel, your own CDN/VPS, or Buddy's Dev Cloud (MicroVM + static hosting).

Common questions
Astro vs Nuxt — common questions
Should I use Astro or Nuxt?
Use Astro for content-driven sites — blogs, docs, marketing — where you want zero JavaScript by default and top Core Web Vitals, and where you're free to mix UI frameworks or use only a little Vue. Use Nuxt when your team is all-in on Vue and you're building a Vue application or a full-stack site: server routes, auth, dynamic data, and the full Vue/Nuxt module ecosystem. Astro can host Vue components as islands, so a mostly-content site that needs a bit of Vue may not need Nuxt at all.
Can I use Vue with Astro instead of Nuxt?
Yes. Astro supports Vue components as hydrated islands via the @astrojs/vue integration. If your main reason to consider Nuxt is "we want Vue," Astro already gives you Vue where it matters while keeping the rest of the page as zero-JS HTML. If you only need a little Vue on a content site, you may not need Nuxt. Move to Nuxt when you need Vue across the whole app plus server routes and the Nuxt module ecosystem.
Is Nuxt overkill for a blog or docs site?
Often yes. Nuxt ships the Vue runtime to the client and brings full-stack machinery — the Nitro server, server routes, auto-imports and modules — that a pure content site rarely uses. Astro is lighter for blogs and docs because it renders to HTML and hydrates only the islands you mark, so pages ship far less JavaScript by default. If the site is content-first, Astro is usually the leaner fit.
How hard is it to migrate between Astro and Nuxt?
Vue single-file components port between the two with minor changes, and Markdown/MDX content is portable. The real work is routing, data fetching and server routes: Nuxt's Nitro server routes and auto-imports don't map one-to-one onto Astro's islands and SSR adapters, and vice versa. A content-first site moves fairly quickly; a full-stack Nuxt app with lots of server logic takes longer to re-express.
