Choose between

A new Next.js build or a migration. Same Team Throughout.

Move an existing site to Next.js

We start with a content and URL audit and a performance baseline, then build a React component library in your own repo and handle CMS migration, 301 redirects and SEO and schema parity, so your rankings hold through the move.

01

Next.js website development

App Router builds where each page is prebuilt, server-rendered or refreshed on a schedule, typed end to end in TypeScript.

02

React component libraries

Your design system as typed React components, documented in Storybook, so marketing pages and the product can share the same building blocks.

03

Headless CMS setup

Sanity, Contentful, Payload, Strapi or Storyblok, modeled on how your team publishes, with drafts, previews and roles. The Rx Assistant’s team ships posts on Strapi without touching the front end.

04

Migration to Next.js

From WordPress, Webflow, Gatsby or an older React build. Every URL mapped, redirects and schema carried across, and rankings checked after launch.

05

Performance and Core Web Vitals

Image, font and script budgets, the right rendering per route and edge caching, so LCP and INP stay green as the site grows.

06

Technical SEO, AEO and GEO

Metadata, sitemaps, canonicals and structured data built into the codebase, so search engines and AI assistants can read and quote your pages.

07

Integrations and forms

HubSpot, Salesforce, Segment, GA4, PostHog and your product APIs, wired in with consent handled, so every form and event lands where your team works.

08

Motion and interactive UI

Product demos, calculators and scroll stories built with Motion, GSAP, Rive or Three.js, and kept fast on a mid-range phone.

Frequently asked questions

Straight Answers. No fluff.

How long does it take to build a Next.js website?

Rango typically ships a focused Next.js marketing site in four to six weeks, from wireframes to launch. Scope, how ready your content is, and how many integrations are involved all move that. On the scoping call, we will tell you which timeline your project fits.

How much does a Next.js website cost?

Rango’s fixed-scope builds start at $1,500, and the final number depends on scope. What moves it: how many page templates you need, the CMS and integrations involved, any migration work, and whether you want a component library your team can extend. We contract in USD.

Can our marketing team edit a Next.js site without developers?

Yes. We set up a headless CMS such as Sanity, Contentful, Payload, Strapi or Storyblok, with drafts, previews and roles, so marketers publish pages, reorder sections and update SEO fields without a deploy. The Rx Assistant’s team publishes on Strapi without touching the front end. New components and layout changes still go through code, and we say so up front.

Should a B2B company choose Next.js or Webflow?

Choose Next.js when the site needs to live in your codebase, share components with your product, handle complex integrations or scale to thousands of pages. Choose Webflow or Framer when marketing wants full visual control without engineers. We build on all three and recommend the one your team can run.

Can you work in our existing Next.js codebase?

Yes. We often start inside an existing repo. We follow your conventions, linting and CI, and open pull requests your engineers review before anything merges. AI helps with repetitive work, such as turning approved designs into typed components, and that work goes through the same review.

Can you migrate our WordPress or Webflow site to Next.js without losing rankings?

Yes, when the mapping is done before launch. We map every URL, set up 301 redirects, carry content and structured data across, and keep metadata and canonicals intact. After go-live we watch Search Console and fix any page that drops.

Who owns the code, and where is the site hosted?

You do. We work in your GitHub from the first commit, and the site runs on your own Vercel, AWS or Cloudflare account. IP is assigned to you, and the repo, docs and CMS stay with your team after handover.

Can a US company work smoothly with a team in India?

Yes. We work in your time zone, so feedback turns around in hours, not a day later. Contracts are in USD, IP is assigned to you, and MSAs and NDAs follow the terms US companies expect. The designers and engineers who build your site stay on the project, with no account manager in between.
