Next.js development for web apps that need to be found

We build Next.js products where the public pages must rank and the logged-in app must feel fast. React on the front, a Node backend and PostgreSQL behind it, all owned by you.

Next.js development for web apps that need to be found

Next.js is a framework built on React, maintained by Vercel and released as open source. Plain React sends an empty page to the browser and builds the content there. Next.js can prepare pages on the server first, so visitors and search engines receive real content straight away. It also handles routing, images and page-level performance, which are the dull jobs every web product needs done properly.

Choose Next.js when your product has two faces: public pages that must load quickly and rank in search, and a logged-in application behind them. SaaS products, marketplaces, directories and online stores with custom logic all fit this shape. If you only need a five page brochure site, it is more than you need. If you only need an internal dashboard that nobody will ever search for, plain React will do the job with less to maintain.

Our take: next.js should be your front end and a thin layer of server code, not your entire backend. Once payments, background jobs and integrations arrive, put them in a proper Node service with its own database. Products that skip this step become hard to change within a year.
What we build with it

Next.js, in practice

SaaS products

Marketing site, sign-up, billing and the application itself in one codebase, with Stripe subscriptions and role-based access.

Marketplaces and directories

Thousands of listing pages rendered on the server so each one can be indexed and shared.

Custom online stores

Storefronts with pricing rules, configurators or subscriptions that an off-the-shelf store builder cannot handle.

Customer portals

Logged-in areas where your clients see orders, documents and invoices without emailing your team.

Content-led sites at scale

Guides, comparison pages and landing pages generated from structured data rather than written into templates by hand.

AI product front ends

Chat, document and search interfaces that stream responses from an AI backend to the browser.

Is it right for you

When Next.js fits, and when it does not

A good choice when

  • Search traffic matters to your business model.
  • You need a public site and a logged-in app in one product.
  • You plan a React Native mobile app later and want shared skills.
  • Page speed on mobile connections affects your conversion.

Look elsewhere when

  • A small brochure website, where a simpler build from $1,000 is the better buy.
  • An internal tool with no public pages and a handful of users.
  • A team with no JavaScript experience and no plan to gain it.
How we work

From brief to live product

1

Map pages and rendering

We list every page type and decide how each is rendered: built in advance, on request, or in the browser. This one decision drives speed, search visibility and hosting cost.

2

Staging link by day 3

A working staging URL arrives early with real navigation and layout. You review on your own phone and laptop, and you share it with whoever needs to approve.

3

Build app and backend

Front end, Node API and PostgreSQL database are built in milestones. Authentication, payments and email are wired to live test accounts, not placeholders.

4

Launch and measure

We deploy to hosting in your name, set up analytics and check page speed and indexing. The 14-day bug-fix window starts at launch.

What to watch for

Where this quietly goes wrong

Rendering everything in the browser

It is possible to use Next.js and still ship pages that are empty until JavaScript loads. You pay for the framework and get none of the search or speed benefit. We see this often in AI-generated projects.

Caching private data

Caching makes pages fast. Applied carelessly to logged-in pages, it can show stale information or, worse, one customer's data to another. Public and private pages need different rules.

Usage-based hosting surprises

Some hosting platforms charge per request or per function call. That is cheap at launch and can climb sharply with traffic or heavy image use. Set spending alerts on day one.

Business logic in the front end

Prices, permissions and discount rules placed in browser code can be read and altered by anyone. Anything involving money or access belongs on the server.

Common questions

Next.js, asked and answered

Next.js vs plain React, what is the difference?

React is a library for building interfaces. Next.js is a framework around React that adds server rendering, routing and performance tooling. If your pages need to appear in search results or load quickly on slow connections, use Next.js. If you are building a private dashboard behind a login, plain React is simpler and perfectly adequate.

How much does a Next.js web app cost?

A simple marketing website starts from $1,000 and takes about 5 days. A working MVP with accounts, a database and payments starts from $10,000 and takes about 7 days when the scope is tight. Larger products are quoted against a written scope. You pay per milestone, never the full amount up front.

Do I have to host a Next.js app on Vercel?

No. Vercel is convenient and a fair choice for many early products. Next.js also runs on AWS and other providers as a standard Node application. We choose based on your traffic, budget and data location requirements. Whichever you use, the hosting account is opened in your name so you control it.

Is Next.js good for SEO?

It gives you the right foundations: pages delivered as real HTML, control over titles and metadata, and good loading performance. It does not rank a site by itself. Content, site structure and links still do that work. What Next.js removes is the technical handicap that browser-only React sites start with.

Can you fix a Next.js app built with an AI tool?

Yes, this is a large part of our work. Apps from Bolt, Lovable, v0 or Cursor often have a good interface over demo data, with no real backend separation. We usually keep the approved design and rebuild the data layer, authentication and deployment. If the budget is only one or two thousand dollars, we will say it is not enough.

Should my backend live inside Next.js?

For a small MVP, yes, it keeps things quick and cheap. As the product grows, scheduled jobs, webhooks, queues and integrations are better placed in a separate Node service. We design the first version so that split is a planned step later, not a rewrite forced on you by an outage.
