Next.js App Development Agency
App Router, Server Components, Supabase, Stripe — production web and SaaS MVPs, not a create-next-app dump.
A Next.js agency should ship a hireable App Router repo: server-side auth, a real data model, and deploys you can roll back. We use this stack every week for SaaS and AI products.
Founders come from Vite SPAs that cannot SEO, or from AI builders that exported unmaintainable React. Next.js is the production default for web — see how to build a web app and Next.js SaaS MVP.
Why next.js app development is easy to get wrong
Marketing site and app in two incompatible repos
API keys in client components
No RLS — every logged-in user sees every row
Vercel preview treated as production
What we build

FAQ
Do you only do Next.js?
It’s our web default. We will say Vite if you have a closed dashboard and no SEO.
Can you take a v0 or Lovable export?
Yes — we port the flows into App Router. See v0 / Lovable to production.
AI SaaS on Next.js?
Yes. See /ai/ai-saas-mvp and /stack/nextjs-openai.
