Next.js Agency
We ship Next.js apps with performance budgets and a written data map. Core Web Vitals and consent sit in the build before launch.
- App Router work with clear rendering and caching rules
- Core Web Vitals budgets before launch
- GDPR processors documented with the frontend
Engineering quality, measured on the page
Next.js projects stall when rendering mode and CMS ownership stay vague. We lock SSR, SSG, and ISR choices against the pages that must stay fast.
You get a senior engineer through launch. Marketing tags and third-party scripts stay behind consent where required, with a short runbook for your team.
Selected work with commercial stakes
Discovery and launch on a production stack
User interviews ran in parallel with the build so the site matched what buyers asked for.
Four-market stack under one TechOps lead
Fractional CTO across vegconomist markets plus Cultivated-X: updates, adops, performance, and incident response.
Relaunch study before vendor lock-in
Requirements, localisation, and vendor-scope advice for a multi-market manufacturer relaunch.
From brief to a shippable app
Outcomes and routes
We lock which pages, markets, and metrics count before component work starts.
Architecture and data
Rendering mode, CMS or API contracts, and caching rules written down.
Frontend engineering
Components with performance budgets. Images, fonts, and third-party scripts stay measured.
GDPR and observability
Consent, processors, and basic error or analytics hooks with a data map.
Launch and handover
Staging QA, redirect plan, and a short runbook for deploys and content.
Next.js work we take on
App builds
Marketing sites and product UIs on the App Router with clear ownership after launch.
Core Web Vitals fixes
Find the pages that fail LCP, INP, or CLS and fix the code, images, or hosting that cause it.
CMS and API wiring
Connect headless CMS or backend APIs with typed contracts and editor-safe previews.
Migrations onto Next.js
Move from legacy frontends with redirects, SEO equity checks, and a cutover plan.
When Next.js is the right call
- You need a React frontend with server rendering and clear performance targets
- Content or product data comes from a CMS or API your team already owns
- You want GDPR and Core Web Vitals in the same delivery scope
- You only need a page builder site with no engineering owner
- You want unlimited feature tinkering without a written scope
- You need a pure design refresh with no performance or conversion target
Next.js agency questions
Do you work with the App Router?
Yes. We default to the App Router unless your constraints require the Pages Router, and we write the rendering choice into the scope.
Next.js or a broader React engagement?
If you need the framework, hosting model, and routing rules, start here. For component systems without Next, see our React agency page. For stack-agnostic UI work, see frontend engineering.
How do you handle Core Web Vitals?
We set budgets for LCP, INP, and CLS on the routes that matter, measure on staging, and fix the code or assets that miss the mark before launch.
How do you handle GDPR on Next.js sites?
Consent, processors, and cookie behaviour are part of the build scope. Marketing tags stay behind consent where required, with vendors listed in the data map.
Where are you based?
Registered in Wiesbaden. Discovery and reviews can happen in person in the Rhein-Main region; delivery runs in structured cycles.
