Next.js development
A Next.js development agency that ships custom code, not templates
We're a small, senior Next.js development agency — you work with the person who designs and builds your site, start to finish. No template to rent, no page-builder to outgrow. Just custom React and Next.js on a handful of dependencies instead of hundreds, tuned for high-performance web that loads in a blink and stays yours to own.

Where a template lets you down.
You're renting, not owning
Wix, Squarespace, a WordPress theme, a Webflow plan — with a page builder you rent the platform forever. Cancel and the site goes dark. Try to leave and there's no clean code to take with you.
Templates get slow and stay slow
A theme ships hundreds of dependencies and third-party scripts you never asked for. It's heavy on line one, and every plugin you bolt on to patch it makes the phone load worse, not better.
It breaks the moment you scale
A template built for a five-page brochure buckles under a real catalog, a service-area map, or a login. When you need software behind the marketing site, there's nowhere clean to put it.
"Custom" that's really a handoff
Big agencies sell custom, then pass you to juniors and offshore teams reskinning the same theme. You pay for bespoke and get a template with your logo dropped into it.
Built for how next.js development actually gets bought.
Custom Next.js & React, from a blank canvas
Every site is written by hand in Next.js and React — no theme, no page builder underneath. Salyers Construction's whole site was built from scratch this way, and scored Lighthouse 100 on accessibility, best-practices, and SEO.
Catalogs and instant search at scale
We turn big product ranges into something an engineer can actually navigate. For Belzona Baton Rouge that's 112 products, 200+ application pages, and ⌘K search across the entire catalog — server-rendered so it stays fast as it grows.
Web apps, portals, and booking flows
When a marketing site isn't enough, we build the software behind it — logins, dashboards, and lead flows. America Premier's free-estimate form runs straight into GoHighLevel, validated on both the client and the server.
Performance held to a number
Our builds run on roughly four to seven dependencies instead of hundreds, so pages stay light. That's how we routinely score 100 Lighthouse where it counts and hit sub-second mobile load targets like America Premier's.
Structured data for SEO and AI search
Every page is marked up so Google and AI models can read it. AAS's 77-application taxonomy ships JSON-LD across 22 hub and industry pages, kept consistent by an automated copy linter.
Code you own outright
You get the repo, the design, the content, and the data — no license, no lock-in. Your team can ship the next feature without calling us, or take the whole thing elsewhere.

What does a Next.js development agency actually do differently?
We write custom React and Next.js by hand instead of assembling a theme or page builder. You get a site tailored to your brand, built on a few dependencies instead of hundreds, fast by default — and owned by you outright, code, design, and data included.
Do I own the code you write?
Yes — outright. The repo, the component system, the content, and the data are yours. There's no page-builder license to keep paying and no lock-in. Your team can extend it or move it anywhere without us.
How is a custom build faster than a template?
Templates ship hundreds of dependencies and third-party scripts you can't remove. Our builds run on roughly four to seven, server-render by default, and get a performance budget from line one — which is how we routinely hit 100 Lighthouse and sub-second mobile loads.
Can you build web applications, not just marketing sites?
Yes. Beyond marketing sites we do custom web application development — logins, client portals, dashboards, catalogs, and booking flows. America Premier's estimate flow runs into a CRM; Belzona Baton Rouge's catalog carries 200+ pages and instant ⌘K search across 112 products.
How much does a custom Next.js build cost, and how long does it take?
Most projects land between $5k and $50k and ship in one to three months, depending on scope — a focused site versus a full catalog or web app. Tell us what you're building and we'll reply within one business day with a straight scope, cost, and timeline.
