React and Next.js apps
your team can build on
We build web apps and sites in React and Next.js: pages that load quickly, parts your team can reuse, and upgrades that stay routine, so your product keeps moving.
Thanks, we’ll be in touch soon.

You’re in good company
A few of the companies we’ve worked with.
When the front end slows you down
React apps often get harder to change as they grow. Components get copied instead of shared, and data is fetched in several different ways. Versions fall behind, and pages slow down on phones. The cause is rarely React itself. It’s usually how the app was put together.
What we build
Front ends your team can extend, test and upgrade without starting again.
New web apps in React
Interfaces made from small components, each with one job, written in TypeScript so many mistakes show up before release.
Sites and apps in Next.js
Public sites and signed-in apps on one framework, with routes, data and rendering set page by page.
Design systems
One shared set of components and the rules for using them, so each new screen starts from parts that already work.
Moves to React from older front ends
A few screens at a time, with old and new running side by side until the last one is across.
Upgrades to current versions
React and Next.js brought up to date in planned steps, using the official upgrade guides and, for Next.js, its automated code changes.
Connections to your APIs and systems
Your back end, payments, search and sign-in wired in, with secret keys kept on the server, never sent to the browser.
Speed
Measured on ordinary phones and connections, then improved where it counts: what shows first, what can wait and what never needs to reach the browser.
Accessibility
Built to WCAG 2.2 at level AA unless you need another, so screens work from the keyboard and make sense to screen readers.
Tests
Automated checks around the parts that matter most, run on every change, so a fix in one place doesn’t quietly break another.

Each page rendered where it works best
Next.js can prepare a page ahead of time, or on the server as it’s asked for, and run the parts people tap and type into in the browser. Parts of one page can differ.
So we choose part by part: what can be ready before anyone asks, what has to be current for each visitor, and what has to answer a tap at once.
Pick a page
{{ rdStatus }}
- Prepared ahead
The article. The same for every reader, so it’s ready before anyone asks, and prepared again when an editor changes it.
- On the server
Your reading list. Belongs to the reader who’s signed in, so it’s prepared for them as the page is asked for.
- In the browser
The save button. Answers a tap at once, without loading the page again.
- Prepared ahead
Photos and description. They change rarely, so they’re ready before anyone asks.
- On the server
Price and stock. They have to be right at that moment, so they’re checked as the page is asked for and arrive just after the rest.
- In the browser
Sizes and the cart button. They answer each tap at once.
- Prepared ahead
The menu and layout. The same for everyone, so they show at once.
- On the server
Your account’s data. Private to each customer, so it’s prepared on the server, where the keys that reach it stay.
- In the browser
Dates and filters. They change the view as you click, without loading the page again.
Easy to keep up to date
React and Next.js keep releasing new versions. React keeps breaking changes for major versions and, where it can, warns about them ahead of time: its policy is that an app with no warnings on the latest release will work with the next major one. Next.js publishes a guide for each major upgrade, with codemods, automated changes to your code, for parts of its API that are updated or phased out.
We keep dependencies few and current, try each upgrade on a preview copy first, and keep tests around what changes.
Start with a review of your app
The review covers the app you have: its components, its dependencies, its speed and how releases go. You get a written review under three headings, Keep, Fix and Rebuild, and a proposal for the first step.
Starting from nothing? We begin with the screens your users need first and the systems they rely on.
Questions worth asking
Is React the right choice for us?
It suits products with many screens and a lot of interaction, built by a team that will keep developing them. If your site is mostly content your editors run, a content system may suit you better, and we’ll say so.
Web & App DevelopmentReact or Next.js?
React is for building interfaces. Next.js is a framework built on React that adds routing, rendering on the server and ways of fetching data. For most new sites and apps we’d suggest Next.js; a front end inside a larger product may need only React.
Can you take over our existing app?
Yes, however it’s built today. We read the code and how it ships before changing anything, then start with what slows your team down most.
Can you move us from an older front end?
Yes, a screen or a feature at a time, so the product keeps working while it moves.
Legacy ModernizationWho hosts it?
Hosting and the platform beneath your app are a service of their own.
Cloud, DevOps & SecurityWho looks after it once it’s live?
We can: updates, security fixes and monitoring on a regular rhythm, with agreed response times, from a team that knows your app.
Support & MaintenanceWill it be accessible?
Yes. We build to the current standard, WCAG 2.2, at level AA, unless you need another.
AccessibilityWhat does it cost?
It depends on what the app has to do and how much of it exists already. You get a written proposal before any work starts: the scope, the price or rate, and how you pay.
PricingCould we add React developers to our own team instead?
Yes. Our React developers can join your own team instead, and you meet each one before choosing who starts.
Hire React DevelopersDo you build mobile apps with React Native?
Apps for phones are our mobile work: iOS and Android apps, native or cross-platform, built on the same back end as your web product.
Mobile App DevelopmentCan you build the back end too?
Yes. We build the APIs and services your app depends on, often as Node.js services written in TypeScript, like the app itself.
