Astro vs Next.js for Your Marketing Site in 2026
Both are excellent. Most brochure sites, landing pages, and blogs do not need a React app framework. Here is when Astro is the grown-up default, and when Next.js earns the complexity.
If you are planning a marketing site in 2026, someone will tell you to use Next.js. Someone else will say Astro. Both are right for some briefs. They are not interchangeable.
I ship with both. The choice follows the job, not the trend.
The job most marketing sites actually have
A homepage. A handful of service or product pages. A blog or news section. Maybe a contact form. Case studies. Pricing. That is the brief for most agencies, freelancers, startups, and local businesses.
Almost none of that needs a live React tree on every page. The visitor is reading, scrolling, and deciding whether to get in touch. They are not running a dashboard.
I have written before about why static sites fit this work. The framework question sits on top of that: do you want a static-first tool that can grow, or an app framework that can also pre-render marketing pages?
What each tool is optimising for
Astro is a site framework. It ships zero client-side JavaScript by default. Pages are HTML unless you opt in. Interactive bits become islands: a mobile nav, a booking widget, a theme toggle. The rest stays calm.
Next.js is a React application framework. It is excellent at routing, data fetching, auth, server components, and the long tail of product features. It can also generate static pages. That does not mean a twelve-page brochure site should start there by default.
Put simply: Astro assumes most of your site is content. Next.js assumes most of your product is an application. Marketing sites usually look like the first case.
Where Astro wins for marketing
Performance without a performance meeting
Astro’s default output is HTML and CSS. You do not spend the first week stripping unused client bundles from a React starter. Core Web Vitals are easier when the page arrives complete and hydration is optional.
That matters for landing pages and ad campaigns as much as for SEO. Slow templates hurt quality scores. Heavy page builders and SPA-shaped marketing stacks make the same mistake in different clothes.
Content that lives in Git
Astro content collections give you schemas for posts, case studies, and team bios. Markdown and MDX sit in the repo. Preview deploys, pull requests, and rollbacks work the way developers already work.
That model pairs cleanly with AI as a CMS: edit copy in plain English, review the diff, ship. You are not fighting a CMS dashboard and a React app for a headline change.
Bring your own UI, only where it proves its worth
Need a React carousel? Drop it in. Prefer Vue or Svelte for one island? Fine. The rest of the site does not become a React app to justify one interactive component.
Room to grow without starting in app mode
Astro is static-first, not static-only. Endpoints, on-demand rendering, and actions exist when a form or API genuinely needs a server. You are not locked into a dead end. You are also not paying app-framework overhead on day one.
For agency sites, portfolios, docs, and campaign pages, this is the sweet spot.
Where Next.js earns its keep
Next.js is the better default when the site is the product, or when marketing and product share one codebase tightly.
Reach for Next.js when you need:
- Authenticated areas — dashboards, account settings, billing portals
- App-like interaction — complex client state, real-time updates, heavy forms that feel like software
- A React team already standardised on it — hiring, shared components, design systems built for React
- Server-driven product features — personalisation that depends on session, permissions, or live inventory at scale
A marketing site bolted onto a Next.js SaaS can be a sensible choice. A standalone brochure site that will never need those features usually is not.
Next.js can pre-render marketing pages well. The cost is cultural and technical: more moving parts, more ways to accidentally ship a client bundle, more “we might need this later” architecture for a site that needed Markdown and a contact form.
Honest trade-offs
| Astro | Next.js | |
|---|---|---|
| Default output | Static HTML, JS only where opted in | React app with many rendering modes |
| Best fit | Marketing sites, blogs, docs, landing pages | Products, dashboards, authenticated apps |
| Content model | First-class collections, Markdown/MDX | Flexible, but content is not the centre of gravity |
| Team shape | Works well for small teams and content + code in Git | Strong when the org already lives in React |
| Risk | Underbuilding if you actually need a full app | Overbuilding a brochure site into an application |
| Hosting | Any static host; adapters when you need a server | Often Vercel-shaped; portable, but ecosystem pulls that way |
Neither tool is “dead” or “winning.” The mistake is treating Next.js as the default website stack because it is popular for products.
A practical decision rule
- Brochure site, portfolio, blog, campaign landing pages? Start with Astro.
- Marketing pages plus a real product in the same app? Next.js is often cleaner than running two frameworks for the wrong reasons.
- Not sure yet? Build the marketing site in Astro. If the product later needs Next.js, that is a product decision, not proof you chose the wrong homepage stack.
- Coming off WordPress? A static Astro rebuild is usually the lighter path. I have argued why WordPress is a weak default for new brochure sites; the destination stack still has to match the brief.
If you only remember one line: use Astro for sites people read, Next.js for software people use. Plenty of projects blend both jobs. Be honest about which job is primary.
What I recommend clients in practice
For most of the marketing and agency work I take on, Astro is the default. Fast pages, content in Git, islands for the interactive bits, hosting that stays cheap. Templates like Astro Base and Astro x Claude exist so teams can start closer to that shape.
When a brief needs auth, app routes, and a React product surface, I use Next.js without apology. The point is not tribal loyalty. The point is not paying for an application framework when you asked for a website.
