How to hire a Next.js developer for a startup.

Next.js is the default way to build a serious web product in 2026, which means everyone lists it on their profile. The difference between a developer who has shipped with it and one who has installed it shows up in your Lighthouse score, your search rankings and your hosting bill. Here is how to tell them apart before you pay.

What a real Next.js developer knows

  • The App Router and React Server Components: what runs on the server, what runs in the browser, and why it matters for speed and for search
  • TypeScript in strict mode, so the codebase can be handed to the next person
  • Core Web Vitals: what LCP, INP and CLS mean and how to keep them green
  • SEO as engineering: server rendering, metadata, structured data, sitemaps, canonical URLs
  • A backend: auth, a database, an API, usually on Supabase, Postgres or a serverless platform
  • A deploy pipeline: preview deployments, environment variables, a domain wired up properly

Five questions to ask

  • Show me a live site you built with Next.js, and let me run Lighthouse on it
  • Which parts of this page would you render on the server, and why?
  • How will this site rank for the things my customers search?
  • Who owns the code and the accounts when we are done?
  • How do we communicate, and what happens if I am asleep when you are working?

Red flags in a quote

  • No live work to show, only screenshots
  • Login, search or SEO listed as paid add-ons
  • Extra pages priced as a percentage of the base
  • A retainer required before a single page ships
  • A timeline with no written scope attached to it

What it costs

At DevLune a website starts at ₹10,000 (3-5 weeks weeks) and a full web product at ₹45,000 (8-12 weeks weeks). Both include the first 5 pages, SEO basics, analytics and deployment, with the source code handed over. Every figure is negotiable and the proposal is written before any money moves.

How an engagement works here

  • Describe the project on the contact page, or get an instant estimate with no sign-up
  • A written proposal and an itemised quote arrive, usually within 24 hours, in one private project link
  • Accept and sign there; work starts on the advance
  • Progress, payments and files all live in that one link; no sales calls at any point
