Problems we are usually asked to fix
React and Next.js power many of the fastest, most search-friendly websites and web apps today.
Read the full overview
We use them to build marketing sites that load quickly and rank well, and web apps and dashboards that feel instant to use. Our team works in TypeScript with the App Router, React Server Components and a tested component library, so your product is quick for users and easy for any React developer to pick up later.
A slow React site
Large bundles and client-side rendering make pages slow on phones and weak in search.
Stuck on old versions
The app runs on old React, the Pages Router or Create React App, and upgrades keep slipping.
Inconsistent UI
Every screen is built differently, so new features take longer and look out of place.
No tests
Releases break things that used to work, so the team is afraid to change code.
Hard to hire for
Custom tooling makes it hard for new developers to get productive.
Outcomes
What you get
- Pages that load quickly on phones as well as desktops
- Better search visibility from server rendering and clean metadata
- A component library that speeds up every new feature
- TypeScript code that other React developers can pick up easily
- Automated tests that catch problems before release
- Code and hosting accounts owned by you

Questions, answered
It depends on the number of pages or features, design work, integrations and testing needs. We send a written estimate after a short call. As a guide, a Next.js marketing website usually costs $6,000 to $25,000, and a custom React or Next.js web app $25,000 to $120,000 or more (USD). Hiring a dedicated React developer usually costs $20 to $60 per hour (USD).
React is a library for building user interfaces. Next.js is a framework built on React that adds routing, server rendering, image optimization and hosting conventions. For public websites and most web apps we use Next.js; for apps behind a login with no SEO needs, plain React with Vite can be simpler.
Yes. Pages are rendered on the server or at build time, so search engines see full content, and Next.js has built-in tools for metadata, sitemaps and images. Good SEO still depends on content, structure and speed, which we plan for.
Vercel is the simplest option. We also deploy Next.js to AWS, Google Cloud, Azure, Cloudflare or your own servers with Docker, depending on cost, data location and your existing cloud.
Yes. We upgrade React and Next.js versions, move from the Pages Router to the App Router, and replace Create React App or Gatsby set-ups. We plan upgrades in steps so the app keeps running.
Yes, by default. TypeScript catches many bugs before release and makes the code easier for new developers to understand.
Yes. You can hire dedicated React and Next.js developers who work in your tools and process, with a first 15 days free trial. See our hire React developers page for details.
We use accessible component primitives, semantic HTML, keyboard support and visible focus, test with screen readers and automated checks, and aim for WCAG 2.2 AA.
Yes. React Native lets us share logic and some UI with your React web app, and we also build in Flutter and native iOS and Android.
A marketing site often takes a few weeks. A web app takes a few months, depending on features and integrations.
You own the code. We maintain and upgrade the app after launch under a support plan.
We keep dependencies updated, validate input on the server, protect secrets and review security before launch.
