Next.js product engineering at studio quality
Plenty of agencies are built around long retainers. What you actually want is a live site, an app in the stores, and users adopting it.
Design and engineering share one backlog, so the visuals never drift away from what can realistically ship on time.
If that sounds like your situation, Arcode is set up for companies hiring a Next.js agency. A Next.js agency for App Router products, SEO systems, dashboards, and high-performance SaaS frontends.
What you get
- App Router architectures
- SEO and metadata systems
- Design systems in React
- Vercel production delivery
- One studio accountable for the result
- Design and engineering on the same schedule
- Support available after launch
How engagement works
As your Next.js agency, we run a shared backlog, design reviews, and engineering sprints, and you keep one point of contact throughout.
- 01
Discover
Goals, constraints, data sources, and success metrics, all settled before we touch architecture or prompts. The work for teams in France stays tied to the outcome you asked for.
- 02
Design
System design, AI/tool boundaries, interface direction, and interaction prototypes. You see progress on the critical path every week.
- 03
Build
Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. Nothing here waits on a handover between separate teams.
- 04
Launch
Ship, monitor, harden, and keep improving models, tools, and product after go-live. On Next.js development projects we favour practical architecture over trendy defaults.
How we build it, and why
The stack is chosen per project, not applied from a template. For Next.js agency work these are the defaults, and the reason each one is on the list.
- Next.js
- server rendering and static generation in one framework, so marketing pages stay fast and app routes stay dynamic
- React
- the component model most teams can already hire for and maintain
- TypeScript
- types across the whole stack, which catches the class of bug that only shows up in production
- Tailwind
- design decisions stay in the markup, so the CSS does not grow faster than the product
- Vercel
- preview deploys on every branch, so review happens on a real URL instead of a screenshot
What the first weeks look like
- Week 1
Scope and architecture
Users, data, integrations, and constraints, ending in a written plan for the Next.js development that you approve before anyone opens an editor.
- Weeks 2-3
Design the critical path
The screens that carry the product, prototyped and clickable. Design and engineering review together, so nothing gets drawn that cannot ship.
- Weeks 4-8
Build in weekly slices
Every week ends with something on a real URL. app router architectures lands early, because the rest of the plan depends on it working.
- Launch
Ship, measure, hand over
Release, monitoring, analytics, and a documented handover, so your team can carry it without calling us.
Weighing up your options
There are three realistic ways to get this built. Each is the right answer for someone.
A solo freelancer
Cheapest per hour and fine for a contained task. The risk on Next.js development is breadth — one person covering design, backend, infrastructure, and launch usually means one of them is weak, and there is no cover when they are unavailable.
A local agency in France
Same timezone and a face to meet, which genuinely matters for some teams. You are also paying French brands seeking polished product UX with strong engineering. rates for the whole team including the layers that never touch your Next.js development, and a local shortlist is a small shortlist.
Arcode
A small senior team. The people who scope the Next.js development write the code, you get weekly demos instead of status decks, and the engagement ends when the thing is live and handed over.

Working with teams in France
French brands seeking polished product UX with strong engineering. Work is remote-first (CET/CEST), with written updates you can read in your own time. We usually collaborate in French/English.
How we work with France teams
France is three to four hours behind us, so the afternoon is shared in full. Work is delivered in English; French-language briefs are fine to send, and documentation and updates come back in English unless you need otherwise.
What France clients usually need
French briefs often pair a strong brand with an ageing site — a marketing-led rebuild where the design matters as much as the stack underneath it. Marketplace and subscription products are the other recurring theme.
Contracts, data, and compliance
GDPR and CNIL guidance drive the data decisions, so consent handling and analytics get scoped properly instead of being dropped in as a cookie banner at the end. We invoice in EUR with reverse-charge VAT for registered businesses.
