Choosing the right stack

When Next.js is the right choice.

Not every website needs a custom application framework. We recommend Next.js when your product requires deeper functionality, integrations, and engineering control.

  • Your product has real application workflows.

    Users need accounts, permissions, dashboards, transactions, and connected data.

  • Your systems need to work together.

    You need to connect APIs, external services, a database, or internal business tools.

  • Your product will keep evolving.

    New workflows, integrations, and features need an architecture your team can maintain.

  • You need control over the implementation.

    Your engineering team needs access to the code, deployment configuration, and technical decisions.

When another platform makes more sense

If your main goal is a marketing website with frequent visual updates and limited custom application logic, Framer, Webflow, or Astro may be a better fit. We'll recommend the approach that matches your team and requirements.

What we engineer

Software built around how your business works.

From the interfaces customers use to the systems behind them, we connect design and engineering into one product experience.

    Performance & production readiness

    Rendering, caching, accessibility, security reviews, and performance checks appropriate to your product.

  • 06

    Documentation & handover

    An organized codebase, agreed documentation, and a walkthrough for your team.

How we work

From product requirements to production-ready software.

We define what needs to work, design the experience, build the application, and validate it before handover. You review the work at agreed milestones.

Explore our process
  1. 01. Discover & Define

    Define what the product needs to do

    We map users, workflows, integrations, technical constraints, and the first release before deciding what to build.

  2. 02. Design & Architect

    Design the experience and its foundation

    We connect interface design with application architecture, data requirements, and the user journeys that matter.

  3. 03. Engineer & Test

    Turn designs into working software

    We develop the application, connect services, implement permissions, and test critical workflows as features are completed.

  4. 04. Launch & Handover

    Prepare for launch and what comes next

    We review functionality and performance, address agreed issues, and deliver documentation and access so your team can continue.

Choosing a platform

The right platform for the job.

We choose technology based on what needs to work, who will maintain it, and how the project is expected to evolve.

FAQ

Questions about Next.js Development

  • How much does a Next.js project cost?

    Projects start at $8,000. Final pricing depends on the scope, integrations, design requirements, and complexity of the software. We agree on deliverables, timeline, and cost in writing before work begins.

  • Can you rebuild or migrate our existing website or app?

    Yes. We first review your current platform, content, application logic, integrations, and SEO requirements. Then we recommend what can be migrated, what needs rebuilding, and how to reduce disruption during the transition.

  • Do you handle design and development together?

    Yes. We can work from your existing designs or handle product UX, interface design, and Next.js engineering as one engagement. This helps align the user experience with technical requirements before development begins.

  • Can you connect our existing tools, database, and APIs?

    Yes, depending on the systems involved and their available integrations. We assess authentication, data flow, permissions, and API limitations before defining the technical scope.

  • How do you approach performance, security, and SEO?

    We plan performance, security, and search requirements around the product. That can include rendering and caching strategy, access controls, image optimization, metadata, and testing. Exact checks and targets are agreed as part of the scope.

  • Can our team maintain the product after launch?

    We aim to deliver readable, organized code and agreed documentation so your developers can continue the work. If your team needs onboarding, a walkthrough, or ongoing support, we can scope that separately.

  • Who owns the code and repository?

    Your agreement defines ownership and handover. For custom development, we aim to keep the repository, deployment access, and agreed project files under your control, subject to third-party tools and licenses.
