Next.js product engineering at studio quality
Big agencies are slow to decide, and a single freelancer can struggle with the full breadth of a product. A studio-sized team sits comfortably between the two.
Projects run on milestones rather than an open-ended discovery phase. Every phase ends with something you can click, test, or release.
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. On Next.js development projects we favour practical architecture over trendy defaults.
- 02
Design
System design, AI/tool boundaries, interface direction, and interaction prototypes. The work for teams in Edinburgh stays tied to the outcome you asked for.
- 03
Build
Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. You see progress on the critical path every week.
- 04
Launch
Ship, monitor, harden, and keep improving models, tools, and product after go-live. Nothing here waits on a handover between separate teams.
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 Edinburgh
Same timezone and a face to meet, which genuinely matters for some teams. You are also paying Edinburgh product companies valuing clean engineering and AI. 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 Edinburgh
Edinburgh product companies valuing clean engineering and AI. We work with clients in Edinburgh remotely and keep overlapping hours in GMT/BST. We usually collaborate in English.
How we work with Edinburgh teams
Edinburgh runs on GMT/BST, giving us a full overlapping day. Written updates land before your morning, so the first thing you read is what moved since you logged off.
What Edinburgh clients usually need
Edinburgh briefs cluster around SaaS and fintech — Scotland's financial sector pulls a lot of product work with it — alongside university-adjacent research tools that need to become real software.
Contracts, data, and compliance
Financial-sector clients bring security questionnaires and DPAs early, so we handle those upfront and keep personal data in UK or EU regions by default. We invoice in GBP.
