React development agency

React powers the interfaces your customers already use every day. We build React frontends that stay fast and maintainable long after launch — no spaghetti, no rewrite in two years.

React development at ZeroPixel

React is the world's most-used interface library — the technology behind Facebook, Airbnb, and most of the software your team already relies on. It's also the most abused: 'knows React' appears on every CV, and the gap between a working React app and a good one is where most agency budgets quietly die.

ZeroPixel builds React the disciplined way: TypeScript everywhere, components designed for reuse, state kept simple, and rendering paths kept fast. That's the difference between an interface that ships once and one that your business keeps building on for years without a costly rewrite.

We use React across everything we do — inside Next.js for websites and products, in browser extensions, and in the dashboards and internal tools we build for UK businesses. If you have designs that need building, a product that needs a frontend, or a React codebase that's become slow and fragile, that's exactly the work we do.

What we build with React

If it renders in a browser, we've probably built it in React — these four shapes cover most of the requests we get.

Products

Product frontends

Complete SaaS interfaces — onboarding, dashboards, settings, billing — built from a reusable, typed component system.

Dashboards

Dashboards & admin panels

Data-heavy screens with tables, filters and charts that stay responsive at real-world data volumes.

Interactive

Interactive tools

Calculators, configurators, booking flows — the interactive pieces that turn a static site into something customers use.

Modernisation

Frontend modernisation

Replacing jQuery-era or fragile legacy frontends with clean React, incrementally, without stopping the business.

Why hire ZeroPixel for React work

Architecture before code
Most React problems are structure problems. We design the component and data architecture first, so features stay cheap to add in year two instead of becoming archaeology.
Performance discipline
We profile real renders, not vibes — memoisation where it matters, server components where they fit, and interfaces that stay smooth on mid-range hardware, not just a developer's laptop.
Handover you can live with
Typed code, sensible naming, documentation, and a walkthrough for whoever maintains it next. You own the code and you're never locked to us.

React — common questions

React or Next.js — which do I need?
Next.js is React plus the infrastructure around it: routing, server rendering, SEO. If you're building anything with public pages that should rank on Google, you want React inside Next.js. Plain React (with Vite) fits interfaces that live behind a login, embedded widgets, or browser extensions. We build both and will recommend the right one for your case rather than the fashionable one.
Can you work with our existing React codebase?
Yes. We start with a code review and give you a straight assessment — what's solid, what's risky, what it costs to fix versus rebuild. Then we work inside your repository, your conventions and your CI, or set those up if they don't exist. Most codebases are salvageable; we'll tell you honestly when one isn't.
How much does React development cost in the UK?
Focused pieces of work — a dashboard, an interactive tool, a frontend for an existing API — are typically four-figure projects; complete product frontends are quoted on scope. Always a fixed written quote before we start. We're senior-only, which costs more per hour and reliably less per project.
Do you also do the design, or just the build?
Both. Most clients come to us with an idea rather than finished designs, so UI/UX design is part of the service — wireframes, visual design, then the React build, all from one team. If you already have designs from your own designer, we build to them faithfully.
Will our team be able to maintain what you build?
That's a design goal from day one. TypeScript, consistent patterns, tests where they earn their keep, and documentation written for the next developer rather than for show. We also offer ongoing support retainers if you'd rather we stay on — but you're never forced to.

Beyond React

A stack is a set of choices that have to work together — these are the pieces we most often pair with React, and where we do it.
