Jamstack Agency London | Astro, Next.js & Nuxt

Q: How much does a Jamstack website cost in London?

A small Jamstack site starts around £5,000–£8,000. Mid-complexity business sites with headless CMS integration typically run £8,000–£25,000. E-commerce or multi-language builds range from £20,000–£50,000+. Every quote is fixed-fee in GBP. No hourly billing, no scope creep surprises.

Q: Should I choose Astro, Next.js, or Nuxt for my project?

Astro's the right fit for content-heavy sites where minimal JavaScript matters — blogs, marketing sites, documentation. Next.js makes more sense for full-stack applications that need authentication, dashboards, or complex data fetching. Nuxt is worth considering if your team already works in Vue. We recommend based on what your project actually needs, not whichever framework we feel like using that week.

Q: What is a headless CMS and why do I need one?

A headless CMS stores and delivers content via API without dictating how it's displayed. Your content team edits in a familiar interface while developers build the frontend in whatever framework fits. It removes plugin vulnerabilities, enables multi-channel publishing, and means you can swap frontends entirely without touching your content.

Q: How fast are Jamstack websites compared to WordPress?

Jamstack sites typically achieve Core Web Vitals scores two to five times better than WordPress. Pre-rendered pages served from a CDN load in under 100ms — no database query, no PHP execution, no plugin overhead getting in the way. That translates directly into better SEO rankings and bounce rates dropping 20–30%.

Q: Can content editors update a Jamstack site without developers?

Yes. Headless CMS platforms like Sanity and Payload offer visual editing interfaces, live preview, and scheduled publishing. Content editors can create pages, update copy, and manage media without going near the codebase. With Incremental Static Regeneration, changes show up on the live site within seconds of hitting publish.

Q: Do you host Jamstack sites on Vercel or Netlify?

We deploy to both. Vercel is our default for Next.js because of native optimisation and edge functions. Netlify works well for Astro and Nuxt builds — atomic deploys and built-in form handling are solid. Both give you global CDN, preview deploys, and automatic HTTPS. If data residency is a requirement, self-hosted options are available.

What Is a Jamstack Agency?

A Jamstack agency builds websites using JavaScript, APIs, and Markup. Pages are pre-rendered at build time and served from a global CDN — which means no traditional server dependencies, sub-second load times, and the kind of scalability that won't require an emergency call to your hosting provider at 11pm. London Jamstack agencies pair frameworks like Astro, Next.js, and Nuxt with headless CMS platforms and edge hosting because performance isn't optional, it's the whole point.

Your Current Site May Be a Liability

Common gaps we find in nearly every audit.

Your WordPress site's scoring below 50 on Lighthouse and you're haemorrhaging mobile visitors

Risk: Google's page experience signals are actively suppressing your rankings in UK search results.

Your monolithic CMS needs constant security patches and plugin updates

Risk: Miss one, and you're not just dealing with a compromised site — you're potentially in front of the ICO explaining a UK GDPR breach.

Content editors are waiting on developers for every page change and campaign landing page

Risk: Marketing slows to a crawl while competitors launch campaigns weeks ahead of you.

Your hosting bill scales linearly every time you run a promotion

Risk: You're either overprovisioning infrastructure all year or watching the site fall over exactly when it matters most.

Bouncing between designers, developers, and CMS consultants means nobody actually owns the architecture

Risk: Integration bugs pile up with every handoff, and accountability disappears into the gaps.

Your current agency quotes in USD, bills hourly, and shifts scope constantly

Risk: Projects run 40–60% over budget with no fixed deliverables and nothing contractual in GBP.

How We Build This Right

Every safeguard, built in from Day 1.

Static Site Generation

Pages pre-rendered at build time and served from edge nodes worldwide. No server-side processing means no server-side attack surface — and consistent sub-100ms response times regardless of where your users are.

Headless CMS Integration

Content lives in Payload, Sanity, or Contentful, completely decoupled from how it's displayed. Editors get a familiar interface. Developers keep full control over the frontend stack. Neither gets in the other's way.

Edge-First Hosting

Deployed to Vercel or Netlify with automatic global CDN distribution. Atomic deploys, instant rollbacks, and preview environments on every pull request — so you can review changes before they're anywhere near production.

Core Web Vitals Optimisation

Astro's island architecture and Next.js partial prerendering ship minimal JavaScript to the browser. Every build gets audited against LCP, CLS, and INP thresholds. If it doesn't pass, it doesn't go out.

UK GDPR & Cookie Compliance

Privacy-by-design with server-side analytics, consent management, and zero third-party trackers by default. Data residency options are available if you've got UK/EU hosting requirements.

Incremental Static Regeneration

Hybrid rendering revalidates pages on demand without triggering full rebuilds. Product catalogues, blog posts, dynamic content — it all stays current while keeping static performance intact.

What We Build

Purpose-built features for your industry.

Astro Island Architecture

Partial hydration ships zero JavaScript by default. Components only hydrate when they're actually visible, which cuts bundle size by up to 40%.

Next.js App Router

React Server Components, streaming, and Turbopack builds give you full-stack capability at static-site speed.

Nuxt Nitro Engine

Vue-based SSG with edge-side rendering and auto-imports. Fast to develop, deploys cleanly to Netlify or Vercel.

Payload CMS Self-Hosted

TypeScript-first headless CMS you actually own. No vendor lock-in, no per-seat pricing, full admin UI included from day one.

Visual Editing with Sanity

Real-time collaborative editing with GROQ queries and live preview. Content teams can publish without pulling a developer in every time.

Automated Performance CI

Lighthouse CI runs on every deploy. Builds that drop below 95 are blocked from production automatically — no exceptions.

Our Development Process

From discovery to launch. Quality at every step.

Architecture & CMS Selection

Week 1

We audit your content model, traffic patterns, and editorial workflow before recommending anything. You get a technical spec and a fixed quote in GBP, not a ballpark figure that triples by go-live.

Design & Content Modelling

Weeks 2-3

UI design in Figma runs in parallel with CMS schema design. Content types, relationships, and editorial permissions get defined before a single line of code ships. That order matters.

Frontend Build & CMS Integration

Weeks 4-6

Component-driven development in Astro, Next.js, or Nuxt with live CMS data. Preview environments on every branch so stakeholders are reviewing real content — not lorem ipsum.

Performance Hardening & QA

Week 7

Lighthouse audits, accessibility testing, cross-browser QA, and load testing against UK traffic profiles. Every page hits 95+ before we talk about a launch date.

Launch & 30-Day Support

Week 8+

Atomic deploy to Vercel or Netlify with DNS cutover, monitoring setup, and analytics configuration. Every project includes 30 days of post-launch support — because launches aren't the finish line.
