Next.js, Custom Next.js 15 website design and build

Premium Next.js websites, built to rank on day one.

RankSmith builds flagship Next.js 15 marketing sites for South African brands that refuse to compete on a WordPress stack. Every site is designed in code, built against the RankSmith performance budget, and handed over with a full schema graph, a hand written llms.txt, and a repository you own.

From R11 250 setup

The problem

Why do most agency websites fail Core Web Vitals on launch day?

Most agency builds start with a WordPress theme, add a page builder, and layer in tracking scripts until the site looks like what the client asked for. By launch day it is carrying 800 kilobytes of JavaScript, a 4 second LCP, and an INP that Google marks red. RankSmith starts from Next.js 15 with a performance budget written into the brief.

How RankSmith runs Next.js

A four stage method, repeated every engagement.

Stage 01

Discovery and strategy

We run a discovery workshop, pull your current Search Console data, audit your competitors, and land on a site map and target keyword set before any design or code happens.

Stage 02

Design in code

We skip Figma for anything beyond brand exploration. Design happens directly in React and Tailwind so what you approve is what you ship. Every component is owned by you.

Stage 03

Build to budget

The build is held to the RankSmith performance budget from day one. LCP under 1.5 seconds, INP under 100 milliseconds, CLS under 0.05, and total home page JavaScript under 150 kilobytes gzipped.

Stage 04

Launch and handover

We ship on Vercel, migrate DNS, submit the sitemap, validate every schema block, and hand over a repository with full documentation. You can take the codebase anywhere.
