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.

Onde os projetos falham

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.

Conformidade

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.

O que construímos

Ships zero JavaScript by default — partial hydration only loads components when they scroll into view

Bundle size drops 40% because unused JavaScript never ships to the browser

Renders server-side in React with streaming SSR — full-stack routing at static-site speed

Your app handles 10,000 concurrent users on a $20/month Vercel plan without scaling drama

Auto-imports Vue components and deploys to edge with zero configuration required

Content teams launch campaign pages in 12 minutes instead of waiting three days for dev tickets

Your CMS admin lives in your repo — migrate hosts in 90 seconds with zero vendor negotiation

Publishes content in real-time with GROQ queries — editors preview changes without re-deploying

Marketing publishes A/B tests live while developers stay focused on features that actually convert

Blocks deploys below Lighthouse 95 automatically — performance gates run in CI before production

Failed builds never reach production — your Core Web Vitals stay green even when juniors deploy

Nosso processo

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.
Week 7
05

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.

Perguntas frequentes

Quanto custa um site Jamstack em Londres?

Um site Jamstack pequeno começa em torno de £5.000–£8.000. Sites corporativos de média complexidade com integração de CMS headless normalmente custam £8.000–£25.000. Builds de e-commerce ou multi-idioma variam de £20.000–£50.000+. Cada orçamento é preço fixo em GBP. Sem cobrança por hora, sem surpresas de mudança de escopo.

Devo escolher Astro, Next.js ou Nuxt para meu projeto?

Astro é a escolha certa para sites com muito conteúdo onde JavaScript mínimo importa — blogs, sites de marketing, documentação. Next.js faz mais sentido para aplicações full-stack que precisam de autenticação, dashboards ou busca de dados complexa. Nuxt vale a pena considerar se sua equipe já trabalha com Vue. Recomendamos com base no que seu projeto realmente precisa, não em qual framework nos agrada usar naquela semana.

O que é um CMS headless e por que preciso de um?

Um CMS headless armazena e entrega conteúdo via API sem ditar como é exibido. Sua equipe de conteúdo edita em uma interface familiar enquanto desenvolvedores constroem o frontend em qualquer framework que se encaixe. Remove vulnerabilidades de plugin, ativa publicação multi-canal e significa que você pode trocar frontends inteiramente sem tocar no conteúdo.

Quão rápidos são sites Jamstack comparados ao WordPress?

Sites Jamstack normalmente atingem pontuações de Core Web Vitals duas a cinco vezes melhores que WordPress. Páginas pré-renderizadas servidas de um CDN carregam em menos de 100ms — sem consulta de banco de dados, sem execução de PHP, sem overhead de plugin bloqueando o caminho. Isso se traduz diretamente em melhores classificações de SEO e taxas de rejeição caindo 20–30%.

Editores de conteúdo podem atualizar um site Jamstack sem desenvolvedores?

Sim. Plataformas de CMS headless como Sanity e Payload oferecem interfaces de edição visual, preview ao vivo e publicação agendada. Editores de conteúdo podem criar páginas, atualizar copy e gerenciar mídia sem ir perto do código. Com Incremental Static Regeneration, mudanças aparecem no site ao vivo dentro de segundos após pressionar publicar.

Vocês fazem hospedagem de sites Jamstack em Vercel ou Netlify?

Fazemos em ambas. Vercel é nosso padrão para Next.js por causa de otimização nativa e funções edge. Netlify funciona bem para builds Astro e Nuxt — atomic deploys e form handling integrado são sólidos. Ambas oferecem CDN global, preview deploys e HTTPS automático. Se residência de dados é um requisito, opções auto-hospedadas estão disponíveis.
