React for interfaces, Next.js for speed and SEO
React is a JavaScript library for building user interfaces from reusable components. It is ideal for interactive screens: dashboards, forms, configurators and anything that changes without reloading the page.
Next.js is a framework built on React. It can render pages on the server or ahead of time, so search engines and visitors receive complete HTML quickly. That makes it a good choice for websites that must rank in Google and still feel like an app.
We used Next.js and React for the Ad Ventures website. React and Next.js are part of our web application development and website development services.
Who this service is for
- Start-ups building a SaaS product or MVP with a modern front-end.
- Businesses that want a fast, SEO-friendly website with app-like features.
- Teams with an existing React app that needs new features or better performance.
- Companies moving an older JavaScript front-end to React or Next.js.
Our React & Next.js services
Next.js websites
Server-rendered or static pages that load fast and are easy for search engines to read.
React front-ends
Component-based interfaces for web apps, portals and dashboards.
API integration
Connecting your front-end to your back-end, CMS or third-party APIs.

Maintenance
Dependency updates, bug fixes and new features.
When to choose React or Next.js
React alone
Best for apps behind a login, where search engines do not need to read the pages.
Next.js
Best for public pages that must load fast and rank: marketing sites, content, catalogues and SaaS landing pages.

Frequently asked questions
What is the difference between React and Next.js?
React is a library for building user interfaces. Next.js is a framework on top of React that adds routing, server rendering and static generation, which helps performance and SEO.
Is Next.js good for SEO?
Yes, when pages are rendered on the server or generated ahead of time: search engines receive complete HTML. Good content and technical SEO are still required.
Do you also work with Vue.js?
Yes. We also build Vue.js front-ends and choose between React and Vue based on your project and existing code.
Can you improve the performance of my React app?
Yes. We measure first, then reduce bundle size, optimise images and data loading, and fix rendering issues.
Can you join an existing project?
Yes. We can review your code base and work alongside your team.
