Next.js 16 vs Astro: Which Should You Use for a Landing Page?
A practical comparison of Next.js 16 and Astro for building AI startup landing pages — performance, developer experience, and when to pick each.
The Two Contenders
If you're building a landing page in 2026, two frameworks come up more than any other: Next.js and Astro.
Both are modern. Both are fast. Both have large communities. But they're optimized for different things, and choosing the wrong one means either fighting the framework or shipping something you didn't intend.

This article compares them for one specific use case: building an AI startup landing page. The comparison covers performance, developer experience, ecosystem, and total cost of ownership.
What Each Framework Is Optimized For
Next.js is a full-stack React framework. It handles static pages, server-rendered pages, API routes, and client-side interactivity. It's designed for applications that grow from a landing page into a full product.
Astro is a content-first framework. It ships zero JavaScript by default, uses an "islands" architecture for interactivity, and is optimized for content-heavy sites like blogs, documentation, and marketing pages.
The core difference: Next.js assumes you'll need a backend eventually. Astro assumes you won't.
Performance
Both frameworks are fast when used correctly.
Next.js 16 ships with Turbopack, static generation, and automatic image optimization. A well-built Next.js landing page will score 95–100 on Lighthouse. The Velat theme, for example, scores 100/100.
Astro ships zero JavaScript by default, which makes it marginally faster for pure content sites. A well-built Astro site will also score 95–100 on Lighthouse.
In practice, the performance difference between the two is small. Both are fast enough that users won't notice a difference. If you're optimizing for the last 100 milliseconds, Astro has a slight edge. If you're optimizing for developer experience and future features, Next.js wins.
Developer Experience
Next.js uses React. If you know React, you know Next.js. The App Router introduces some new concepts (Server Components, async params, streaming) but the fundamentals are the same.
Astro uses a component model that supports React, Vue, Svelte, and other frameworks in the same project. You can write .astro files (Astro's own syntax) or use your framework of choice.
Astro's syntax is closer to HTML — you write markup and add interactivity where needed. Next.js's syntax is fully React — everything is a component.
For developers already comfortable with React, Next.js is the easier choice. For developers coming from a traditional web background, Astro's HTML-first approach feels more natural.
Content Management
Both frameworks support Markdown and JSON for content.
Next.js requires you to write a loader that reads files from disk and parses frontmatter. This is straightforward but manual. The Velat theme uses this approach — about 50 lines of TypeScript.
Astro has built-in content collections. You define a schema, add Markdown files, and Astro handles the rest. Type safety is automatic.
Astro's content system is more polished out of the box. Next.js requires more setup, but gives you more control.
Ecosystem
Next.js has the largest ecosystem of any React framework. Every React library works with Next.js. Every Next.js tutorial you find online is probably up to date.
Astro has a smaller but growing ecosystem. Most integrations work, but some React-specific libraries don't translate directly.
If you need to integrate with a specific tool — auth providers, payment processors, CMSs — check that it has official Next.js support first. It usually does.
Hosting and Deployment
Next.js deploys best to Vercel (built by the same team). It also works on Netlify, Cloudflare Pages, AWS Amplify, and any Node.js host.
Astro deploys anywhere that serves static files. It's slightly more portable because it doesn't require a Node.js runtime for basic sites.
Both are easy to deploy. Next.js has more platform-specific features (like ISR and edge functions) that only work on certain hosts.
When to Use Next.js
Use Next.js if:
- ―You're building a product that will grow beyond a landing page
- ―You need server-side rendering for dynamic content
- ―You plan to add authentication, payments, or a dashboard later
- ―You want the largest ecosystem and community
- ―You're already comfortable with React
The Velat theme is built on Next.js because most AI startups fall into this category. The landing page is the first step. The product comes next.
When to Use Astro
Use Astro if:
- ―You're building a pure content site — blog, docs, marketing pages
- ―You don't need server-side rendering
- ―You want the absolute fastest load times
- ―You want to use multiple UI frameworks in one project
- ―You're building a static site that won't grow into an application
Astro is excellent for blogs and documentation sites. For a landing page that's part of a larger product, Next.js is usually the better fit.
The Realistic Comparison
In practice, the choice comes down to one question: will this site grow into an application?
If yes, use Next.js. You'll save yourself a migration later.
If no, either works. Astro is slightly faster and slightly simpler. Next.js is more flexible and has a larger ecosystem.
For an AI startup landing page, the answer is usually yes. You're not building a brochure — you're building the front door to a product. The site will grow. Plan for it.
Can You Use Both?
Yes, technically. Astro supports React components, so you can use Next.js-style components inside Astro. And Next.js can serve static content generated by other tools.
But mixing frameworks adds complexity. For a landing page, pick one and commit. The friction of mixing isn't worth the marginal benefit.
What the Velat Theme Uses
Velat is built on Next.js 16 with the App Router. Reasons:
- ―Server Components by default — fast, correct, and modern
- ―Static generation — every page is pre-rendered at build time
- ―TypeScript throughout — no untyped code
- ―Tailwind CSS — utility-first styling with a custom design system
- ―Markdown content — blog and products are just files in a folder
- ―Zero config deployment — works on Vercel, Netlify, Cloudflare
The theme is fully static. It builds to 28 pre-rendered pages. There are no serverless functions to run. Performance is consistently fast worldwide.

Conclusion
Next.js and Astro are both excellent frameworks. The right choice depends on what you're building.
For an AI startup landing page that will grow into a product, Next.js 16 is the safer bet. It's more flexible, has a larger ecosystem, and scales from landing page to full application without a rewrite.
For a pure content site, Astro is slightly better. It's faster, simpler, and more portable.
Both are good. Pick based on where you're going, not where you are.
