Next.js Development Services

Ask how they decide the rendering mode of each page, how they cache data and refresh it after an editor publishes, what the site shows when the CMS or an API is down, and how they handle major version upgrades. Ask to see code or a live product the team built — a design portfolio proves nothing about engineering. On your project, the route map and one route live on a preview URL come before you commit to the rest.

A technical scope with a route map and acceptance criteria; the repository, environments and preview deployments; routes, layouts and components for every page type in scope; server logic, data fetching and caching; a headless CMS, sign-in, payments and other integrations in scope; metadata, sitemaps, redirects and structured data; tests, speed, accessibility and security checks; monitoring; a staged release; and the handoff. On an existing Next.js codebase we start with a short review of versions, routing and caching, then agree what to keep, fix or rebuild.

Next.js suits a product whose public pages must rank and load fast and whose signed-in part shares the same code, such as a marketplace, a SaaS site with its app, or a store. If everything sits behind a sign-in, plain React is simpler to run. Where pages are mostly read and only a few parts respond to input, Astro is lighter and needs no Node server. If marketing wants to build pages visually, Webflow may serve better. We say which one fits during scoping, before any code.

No. Vercel makes for the simplest deployment and previews, but Next.js also runs on your own cloud as a Node server or a container, and some pages can be exported as static files. Features and costs differ between hosts, and traffic-based pricing is worth modelling before launch. We agree the host in the scope, and the account is in your name either way. Every change also gets a preview link, so your team reviews real pages rather than screenshots.

Yes, route by route, with the old site running until each part is replaced. We list the URLs that must keep working, map them to new routes or redirects, and move content and data by script. A single-page React app usually moves page by page, starting with the public routes that need server rendering most. A move of the whole platform is Website Migration & Replatforming, with its own scope.

A page list or sitemap with approved designs for each page type, access to the content and the CMS your editors will use, API documentation and sandbox keys for each service, a decision on hosting or time to make one together, the live URLs that must keep working, and one person who approves each slice. If the design or content is not ready, the route map and foundation can start while they are finished.

As written acceptance criteria agreed before the build. Typical ones: a speed budget for key routes, metadata and a sitemap on every indexable page, working redirects, keyboard and screen-reader use on key flows, security headers, no secrets in the browser bundle, and alerts that reach a named owner. We check each release against them. We do not promise rankings or scores for the whole site.

The source code in your repository, the app on your hosting account, documentation of the routes, rendering and data layer, test evidence, release notes, a runbook for deploys and rollbacks, and a map of who owns what. Your engineers can take over. Or upgrades, new pages, a UX Audit, usability testing or product design can continue with us, each on its own scope.

How many page types and signed-in workflows there are, which of them render per request, the volume of content and data to bring across, the CMS and services to wire up, the URLs to keep, your quality bar, and how finished the design is. We set a custom scope and estimate in the proposal, fixed or phased, and agree the timeline once scope, access, dependencies and acceptance criteria are clear. A phased scope often suits: the public pages first, then the signed-in product.

Designing the site or product from scratch, copywriting, backend services beyond the app's own routes, native mobile apps, and the fees and account actions of your hosting, CMS and other providers. Rankings, traffic and revenue depend on far more than the build, so we promise none of them; speed, security and uptime are held to the written criteria.
