Custom Next.js development

A senior-led Next.js shop in the Shenandoah Valley.

Every Mosaic Ridge build is custom-coded in Next.js, React, and TypeScript. App Router, server-rendered, strictly typed, accessibility-first — and the codebase ships to a Git repository you own.

We serve businesses, institutions, and government across Virginia from a Churchville home base. Plans start at $1,800 for productized builds; custom engagements are scoped against your operating model.

The direct answer

Yes — we're a Next.js shop, and we use it for everything we build.

Next.js is the React framework powering production workloads at TikTok, Notion, Twitch, Hulu, Nike, the Washington Post, and tens of thousands of smaller businesses. It renders pages on the server for fast first paint and clean SEO, ships only the JavaScript a given page needs, handles routing and image optimization out of the box, and integrates cleanly with any database or third-party API.

For a Virginia mid-market or institutional client, that translates to: ranks in Google, loads fast on rural broadband, runs on commodity hosting, and any senior web developer can maintain it — which matters more, long term, than which framework is trendy this quarter.

We do not build on WordPress, Squarespace, Wix, Webflow, or any drag-and-drop builder. Those platforms have their place; ours isn't it. We're a custom-coded shop, and Next.js is the framework we use for marketing sites, e-commerce, internal tools, and full-stack applications alike.

What we build with Next.js

Six categories, one framework.

A Next.js codebase is flexible enough to serve a five-page marketing site and a multi-tenant SaaS application from the same architectural foundation. We've shipped variants of all six categories below.

Marketing sites & content platforms
Statically generated pages that load fast on rural broadband, rank in Google, and serve as the public face for institutional and mid-market clients. Editable content, structured SEO, embedded media.
Custom e-commerce on Next.js + Stripe
Storefronts, checkout, subscriptions, and post-purchase workflows built on Next.js and Stripe — no Shopify lock-in, no per-transaction app fees beyond Stripe processing.
Internal tools, dashboards, portals
Member portals, admin dashboards, custom CRMs, booking systems, and inventory tools. Authenticated, role-gated, integrated with the systems your team already uses.
API-backed web applications
Full-stack Next.js applications with PostgreSQL data layers, server-side actions, and integrations with Stripe, Resend, Supabase Auth, and third-party APIs. Scoped per-engagement.
Migrations off WordPress, Squarespace, Webflow
Move the existing site to an owned Next.js codebase without losing SEO. We preserve URL structure with 301 redirects, port existing content, and document the new editor workflow for your team.
Section 508 / WCAG 2.1 AA government builds
Procurement-ready Next.js builds with documented accessibility, OWASP-aware development, signed proposals, and Accessibility Conformance Reports (ACR / VPAT) issued at award.

The full stack

Open-source. Mainstream. Maintainable.

Every layer of the stack is open-source software a senior developer anywhere can read and maintain. Nothing is proprietary to us. Nothing is load-bearing on a single vendor.

Next.js 16
App Router, React Server Components, server actions. Static generation for marketing pages, SSR for authenticated routes — per-route rendering strategy, not a global setting.
React 19 + TypeScript (strict)
Strict mode everywhere. No `any` without an explicit, documented reason. Every API boundary validates input. Type errors fail the build, not production.
Tailwind CSS v4
CSS-based configuration, no plugin-config drift. Built-in design tokens, no runtime CSS-in-JS, no bundle-size regression.
PostgreSQL via Supabase
Row-Level Security on every table. Auth, file storage, and real-time included. Schema-per-project on a shared database for internal projects; dedicated projects for client-facing data.
Stripe, Resend, Vercel Analytics
Stripe for payments and subscriptions, Resend for transactional email, Vercel Analytics and Google Analytics 4 for measurement. All swappable; nothing is load-bearing on a single vendor.
Vitest + React Testing Library
Behavior-tested, not implementation-tested. CI runs lint, type-check, tests, and a production build on every pull request. No green CI, no merge.

Why Next.js

Six properties that make it the right default.

We picked the stack on purpose. Each of these properties was selected against the alternative, not as an afterthought.

Server-rendered HTML for fast first paint and clean SEO

Strict TypeScript — type errors fail the build, not production

WCAG 2.1 AA accessibility built in from the start

OWASP-aware build process; no third-party CMS plugin attack surface

Source code delivered to a Git repository you own

Hosted on the provider of your choice — no Vercel lock-in

Frequently asked

Common questions about our Next.js work.

Why Next.js for a Virginia business website?
Next.js is the React framework powering production workloads at TikTok, Notion, Twitch, Hulu, Nike, and the Washington Post. It renders pages on the server for fast first-paint and SEO, ships only the JavaScript a given page needs, handles routing and image optimization out of the box, and integrates cleanly with any database or third-party API. For a Virginia mid-market or institutional client, Next.js means: ranks well on Google, loads fast on rural broadband, runs on commodity hosting, and any senior web developer can maintain it — which matters more than which framework is trendy this quarter.
What versions and patterns of Next.js do you build on?
Next.js 16 with the App Router and React Server Components by default. We use static generation (SSG) for marketing pages and SSR for authenticated routes — the right rendering strategy per route, not a one-size-fits-all setting. TypeScript is enabled in strict mode on every project, all routes are typed, and every API boundary validates input. Older Pages Router projects are migrated to the App Router on engagement unless there's a specific reason not to.
What's the rest of your stack besides Next.js?
React 19 and TypeScript on the front end, Tailwind CSS v4 for styling, PostgreSQL (typically via Supabase) for the database with row-level security policies, Stripe for payments, Resend for transactional email, Vercel Analytics and Google Analytics for measurement, and Vitest + React Testing Library for the test suite. Every project is version-controlled in Git, deployed via CI on every push to main, and instrumented with structured logging. The whole stack is open-source and self-contained.
Do we have to host the site on Vercel?
No. Next.js runs on any Node.js-compatible host — Vercel, Netlify, Railway, AWS (via Amplify, App Runner, or a standalone Node service), Fly.io, DigitalOcean App Platform, or your own VPS. We default to Vercel because it pairs cleanly with Next.js and the free tier covers most of our marketing clients, but the codebase is not Vercel-specific. The Migration Package transfers the site to a host of your choice if you ever want to leave.
Can our in-house developers contribute to the codebase?
Yes. The repository is created in your GitHub or GitLab account from day one, and we routinely grant in-house teams collaborator access during the build so they can review pull requests, run the code locally, and contribute changes. Because the stack is mainstream (Next.js, React, TypeScript), any developer with React experience can read the codebase without a learning curve specific to us.
Will another Next.js shop be able to maintain this after handoff?
Yes — that is the point of using mainstream frameworks rather than bespoke architectures. We follow conventional Next.js App Router file structure, type everything strictly, document the non-obvious decisions, and avoid clever abstractions a future developer would have to reverse-engineer. A senior Next.js developer can be productive in the codebase within hours, not weeks. This is intentional and a stated deliverable, not an afterthought.
Is Next.js overkill for a small five-page marketing site?
No, and the alternative is usually worse. A small Next.js site statically generates the same five HTML pages a static site builder would, but with a typed component model, automatic image optimization, built-in performance budgets, and a path to add a contact form, a blog, or e-commerce later without rebuilding. The reasonable comparison isn't to a static HTML site — it's to WordPress or Squarespace, where 'small' sites accumulate plugin sprawl, performance debt, and maintenance fees over time. A Next.js Foothold build at $1,800 is a cleaner long-term position.
How does Next.js handle SEO and Core Web Vitals?
Server-rendered HTML means search engines see fully populated pages on first crawl, which is the single biggest SEO advantage over client-rendered React apps. The framework handles per-page metadata, OpenGraph cards, canonical URLs, JSON-LD structured data, and automatic image optimization out of the box. Core Web Vitals — Largest Contentful Paint, Interaction to Next Paint, Cumulative Layout Shift — are reviewed at every milestone with Lighthouse, not just at the end of the build. Every Mosaic Ridge site ships with sitemap.xml, robots.txt, and a baseline of on-page SEO.
