Two frameworks, two different philosophies
Astro and Next.js sit at the top of most shortlists for a new business website in 2026, but they were built to solve different problems. Astro is a content-first framework: it renders pages to plain HTML at build time and ships no JavaScript to the browser unless a component genuinely needs it. Interactive widgets load as isolated islands, so a contact form or image carousel does not drag an entire application framework along with it.
Next.js is a React application framework maintained by Vercel. Server components, nested layouts, streaming and API routes make it excellent for software: dashboards, customer portals and logged-in product experiences. It can produce static pages too, but that is a mode it supports rather than the reason it exists. That difference in intent explains almost every trade-off that follows.
Performance on brochure and content sites
For a services site, a landing page or a blog, Astro's output is hard to beat: plain HTML served from a CDN with kilobytes of JavaScript rather than hundreds of kilobytes. Core Web Vitals, which feed into Google's ranking systems, tend to pass without tuning. Interaction to Next Paint in particular rewards pages that do very little work on the browser's main thread, and a default Astro build does almost none.
A Next.js site can score just as well, but you have to work for it. React hydration cost, client components creeping into pages that should stay static, and misconfigured images or fonts are the usual culprits when a Next.js build scores poorly. Server components have narrowed the gap considerably; they have not removed the need for discipline. On a brochure site, that discipline is effort spent recovering performance that Astro gives you for free.

Build speed and developer experience
Astro's mental model is deliberately small. Pages are files, components look like HTML with a code fence at the top, and content collections give you type-checked Markdown for blogs and case studies. A competent developer can go from empty folder to deployed five-page site in a day, and if a specific widget needs React, Vue or Svelte, Astro will happily render it as an island inside an otherwise static page.
Next.js offers far more machinery: route handlers, middleware, server actions, granular caching. That power is genuinely useful for applications and genuinely confusing for simple sites; the App Router's caching behaviour has been one of the most common sources of developer frustration in recent years. If your project will never use an API route or a database, most of that machinery is weight you carry without benefit.
Hosting costs in the real world
Hosting is where the gap widens for small businesses. Static Astro output is just files, so it runs anywhere, including the cheapest tiers of UK shared hosting. Next.js runs best on Vercel, and running it anywhere else means operating a Node server yourself.
- Astro (static output): free on Cloudflare Pages, Netlify or GitHub Pages, or from roughly £2 to £5 a month on shared hosting such as Hostinger or 20i.
- Astro with server rendering: a small VPS or serverless adapter, typically £5 to £20 a month.
- Next.js on Vercel: a free hobby tier for non-commercial use, then a paid plan per team member, with usage-based charges that can climb on traffic spikes.
- Self-hosted Next.js: a Node-capable VPS from around £10 a month, plus the ongoing time cost of patching, monitoring and restarting it.
Hiring pool and long-term maintenance
React remains the largest front-end talent pool in the UK, so finding freelancers or agencies fluent in Next.js is easy and will stay easy. Astro's pool is smaller but growing, and this matters less than it first appears: an Astro project is mostly HTML, CSS and standard JavaScript, so any capable web developer can maintain one after an afternoon with the documentation.
Maintenance tells a similar story. A static Astro site can sit untouched for a year and keep working, because there is no server runtime to patch. A Next.js application needs dependency updates, and major-version upgrades of React and Next.js are real projects in themselves. Factor in a small ongoing retainer for any Next.js build, and be aware that leaning on Vercel-specific features makes moving host harder later.
Key Takeaway
Pick the framework that matches what you are building, not what is trendy. For brochure and content sites, Astro's static HTML output means faster pages, near-zero hosting cost and far less maintenance. For web applications, dashboards or anything behind a login, Next.js and its React ecosystem earn their complexity. If you need both, split them: Astro for the marketing site, Next.js for the app. Decide on hosting cost and hiring before you decide on syntax.
Our picks by project type
- Brochure or services site (5 to 30 pages): Astro. Fastest pages, cheapest hosting, least maintenance.
- Content-led marketing site with a blog: Astro, using content collections for Markdown posts.
- Marketing site plus a customer portal: split them. Astro for the public site, Next.js for the app on a subdomain such as app.yourdomain.co.uk.
- SaaS product, dashboard or anything behind a login: Next.js. Its application features earn their complexity here.
- Headless ecommerce with heavy filtering and personalisation: Next.js, or Astro with server islands if the interactive surface is small.
The honest summary: choose Astro when the website is the product being read, and Next.js when the website is software being used. Deciding on hosting cost, hiring and maintenance before you decide on syntax will save you an expensive rebuild in two years.
