What Actually Ships When You Choose Jamstack — And What Stays Behind

Your page goes live before the database even wakes up. A Jamstack agency pre-renders every route at build time and serves it from a global CDN — no runtime queries, no server cold starts, no MySQL timeouts killing your checkout flow. Your team gets frameworks like Astro, Next.js, and Nuxt paired with headless CMS platforms that editors can actually use without Slack-tagging a developer. London Jamstack agencies exist because WordPress and monolithic PHP stacks can't hit Core Web Vitals targets without extreme caching gymnastics. Static generation means sub-second loads, zero-downtime deploys, and hosting bills that don't double when your campaign actually works. But pre-rendering breaks the moment you bolt on a legacy CMS that wasn't built for it — which is why the CMS choice matters more than the framework.

Dónde fallan los proyectos

Your WordPress site's scoring below 50 on Lighthouse and you're haemorrhaging mobile visitors Google's page experience signals are actively suppressing your rankings in UK search results.
Your monolithic CMS needs constant security patches and plugin updates 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 Marketing slows to a crawl while competitors launch campaigns weeks ahead of you.
Your hosting bill scales linearly every time you run a promotion 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 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 Projects run 40–60% over budget with no fixed deliverables and nothing contractual in GBP.

Cumplimiento

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.

Nuestro proceso

01

Architecture & CMS Selection

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.
Week 1
02

Design & Content Modelling

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.
Weeks 2-3
03

Frontend Build & CMS Integration

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.
Weeks 4-6
04

Performance Hardening & QA

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

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.

Preguntas frecuentes

¿Cuánto cuesta un sitio web Jamstack en Londres?

Un pequeño sitio Jamstack comienza alrededor de £5,000–£8,000. Los sitios comerciales de complejidad media con integración de CMS sin cabecera típicamente rondan £8,000–£25,000. Las compilaciones de comercio electrónico o multiidioma oscilan entre £20,000–£50,000+. Cada presupuesto es de tarifa fija en GBP. Sin facturación por horas, sin sorpresas de cambio de alcance.

¿Debo elegir Astro, Next.js o Nuxt para mi proyecto?

Astro es la opción correcta para sitios con mucho contenido donde JavaScript mínimo importa — blogs, sitios de marketing, documentación. Next.js tiene más sentido para aplicaciones full-stack que necesitan autenticación, dashboards o búsqueda de datos compleja. Nuxt vale la pena considerar si tu equipo ya trabaja en Vue. Recomendamos según lo que tu proyecto realmente necesita, no según qué framework nos apetezca usar esa semana.

¿Qué es un CMS sin cabecera y por qué lo necesito?

Un CMS sin cabecera almacena y entrega contenido a través de API sin dictar cómo se muestra. Tu equipo de contenido edita en una interfaz familiar mientras los desarrolladores construyen el frontend en cualquier framework que encaje. Elimina vulnerabilidades de plugins, permite publicación multicanal, y significa que puedes cambiar frontends completamente sin tocar tu contenido.

¿Qué tan rápidos son los sitios Jamstack comparados con WordPress?

Los sitios Jamstack típicamente logran puntuaciones de Core Web Vitals dos a cinco veces mejores que WordPress. Las páginas pre-renderizadas servidas desde una CDN cargan en menos de 100ms — sin consulta a base de datos, sin ejecución PHP, sin sobrecarga de plugins en el camino. Esto se traduce directamente en mejores rankings de SEO y tasas de rebote cayendo 20–30%.

¿Pueden los editores de contenido actualizar un sitio Jamstack sin desarrolladores?

Sí. Plataformas CMS sin cabecera como Sanity y Payload ofrecen interfaces de edición visual, vista previa en vivo y publicación programada. Los editores de contenido pueden crear páginas, actualizar copias y gestionar medios sin acercarse al código. Con Regeneración Estática Incremental, los cambios aparecen en el sitio en vivo en segundos después de presionar publicar.

¿Alojan sitios Jamstack en Vercel o Netlify?

Ambos. Vercel es nuestro predeterminado para Next.js debido a la optimización nativa y funciones edge. Netlify funciona bien para compilaciones Astro y Nuxt — deploys atómicos y manejo de formularios integrado son sólidos. Ambos te dan CDN global, deploys de vista previa e HTTPS automático. Si la residencia de datos es un requisito, hay opciones auto-hospedadas disponibles.
