Why Next.js

Why choose Next.js for your website or web app?

Next.js is the React framework built by Vercel, and the one this website runs on. Here's what it means for your business, with results from Next.js sites we've built.

  1. 01

    Pages that load almost instantly

    Next.js prepares each page on the server, so visitors receive a finished page instead of waiting for their phone to build it. Fast pages keep visitors on the site and count towards Google's Core Web Vitals.

  2. 02

    Built to be read by Google and AI answers

    Every page arrives as complete HTML with its own title, description and structured data, so search engines and AI assistants can read all of it, not just what loads first.

  3. 03

    Rich animation without the slowdown

    Each page only loads the code it needs, and animations can be set up just before they're seen. You get a site that feels crafted without the heavy, slow pages that usually come with it.

  4. 04

    Lighter pages for mobile visitors

    Images are resized and converted to modern formats automatically, fonts are served from your own domain, and code is split per page, so phones on slow connections download far less.

    ZetaCore: homepage 82% lighter, 2.4 MB to 444 KB
  5. 05

    Hundreds of pages from one source

    Service, location or product pages can be generated from a single set of data, each with its own address and metadata. Add a new service once and every page that lists it updates.

    ZetaCore: twenty service pages from one data source
  6. 06

    Website and web app in one codebase

    Forms, logins, customer portals, dashboards and payments can live in the same project as your marketing pages, sharing one design system instead of bolting separate tools together.

  7. 07

    Keep the CMS your team knows

    Next.js works with Payload CMS, WordPress, Shopify, Sanity or Contentful. Your team edits pages, products or profiles in a familiar dashboard, in every language you publish, while visitors get a fast, custom front end.

    Easy to hire for, hard to outgrow

    Next.js is open source and built on React, one of the most popular ways to build websites, so plenty of developers know it. It runs on Vercel or any Node.js host, with no licence fees and no lock-in.

An honest answer

When Next.js isn't the right choice

We build on several platforms, so we'll tell you if another one fits better.

  • You want a content site your team builds and edits page by page, with a large choice of plugins.Choose WordPress
  • You want a design-led marketing site edited visually, with hosting included.Choose Webflow
  • You want a standard online store running quickly with as little upkeep as possible.Choose Shopify
  • The heavy lifting is back-office logic: queues, reports, roles and permissions. We often pair it with a Next.js front end.Choose Laravel

Questions

Common questions about adopting, migrating, and scaling with React and Next.js.

Why should we choose Next.js over a traditional CMS?
Next.js offers a hybrid rendering approach (SSR/SSG/ISR) that traditional monolithic CMS platforms (like older WordPress or Drupal builds) simply cannot match. It results in exponentially faster load times, superior technical SEO out-of-the-box, and a developer experience that allows your engineering teams to ship features faster.
How long does a typical migration take?
A standard headless migration typically takes 6 to 12 weeks depending on the complexity of your data models and the number of existing systems we need to integrate with. Our 'Discovery and Scope' phase will precisely map this timeline before any code is written.
Do you integrate with Shopify or WooCommerce?
Yes. We build headless storefronts using Next.js on the frontend, pulling inventory, checkout, and product data seamlessly via Shopify's Storefront API or WooCommerce's REST API.
What happens after the project launches?
We offer tailored retainer agreements for continuous optimization, feature roadmapping, and edge-network monitoring. We don't just build and leave; we partner with your team to ensure long-term scalability.
Can you take over an existing React or Next.js codebase?
Yes. Our senior engineers routinely perform technical audits on existing codebases. We identify anti-patterns, resolve hydration errors, and refactor monolithic state structures into highly optimized, maintainable components before adding new features.
What custom development services does Renav Limited provide?
Renav Limited provides custom React and Next.js development, API integrations, dashboards, SaaS platforms, workflow automation, and secure business web applications.
Who is Renav's custom development service for?
It is for businesses that need a tailored application, internal platform, customer portal, or automation system instead of an off-the-shelf website template.
Can Renav integrate a custom app with existing systems?
Yes. Renav connects custom applications with CRMs, ERPs, payment gateways, communications platforms, analytics tools, and third-party APIs.
