Front-end development:
everything your users see and touch.

Visitors judge you on your screens, buttons and load times. We build them from tested, reusable parts in React and other modern tools. Speed and accessibility targets are agreed before sprint one. 4,500+ projects delivered since 2004.

What we do

PixelCrayons provides front-end development services: the screens your customers see, built in React and other modern tools by one senior team. We turn your design system into a library of tested, reusable parts. Speed and accessibility targets are built in. A senior engineer reviews every change. We work direct for brands and white-label for agencies.

In every front end

What our front-end development
includes.

01

Your design system, built as reusable code

We turn your design files into code step by step. Colours, type and spacing are stored once as variables. Each design component becomes a coded part with all its states, and pages are built from tested parts. You get a library your team can add to. New pages reuse it, and a design change is made once, not page by page.

Every build
02

Accessibility built in from the start

WCAG 2.1 AA is the common standard for accessible websites. We build to it and check it in the browser. That covers clear page structure, keyboard use, visible focus states, screen-reader labels, calmer motion options and colour contrast. Adding accessibility after launch costs more than building it in. It comes as standard, never as an extra.

Included
03

Performance budgets, measured on real devices

Core Web Vitals are Google's scores for page speed and stability. We agree targets for them, and for page size, in writing before sprint one. We measure them on every release, on slow connections and everyday phones. If a feature would break a target, we bring you the choice first, so you never find a slow page later.

Every release
04

A senior engineer reviews every change

No change reaches your live code without a review. A second senior engineer checks each one against a written standard: does it work, is it accessible, is it easy to maintain. These reviews keep the library consistent as it grows. The front end you inherit reads as if one careful author wrote it.

Every merge
05

Checked against the design, then handed over

Every build ends with a written side-by-side check against the design files. We compare colours, spacing, type, states and motion, and fix any gaps within the agreed scope. Then we hand it over. The code sits in your accounts from day one, with IP and ownership terms agreed before work starts. We write the documentation as we build, not at the end.

In writing
How it starts

How a front-end build starts,
from design files to a test site.

01
Start

Brief and access

We sign an NDA. Then we go through the design files and your chosen technology together: parts, states, unusual cases and who looks after it later.

02
Once the brief is complete

Itemised proposal

We confirm when the proposal arrives. It lists every part to build, why we chose the technology, and the speed and accessibility targets. It also shows the order and the price.

03
Your decision

You sign off

You confirm the scope, the payment and the access we need. Nothing starts before this.

04
Typically 2 to 3 business days later

The team starts

We move the design colours, type and spacing into code and set up the project in your repository. Automated checks start running, and a preview link goes live.

05
On the date in your proposal

First deliverable

The main parts and one priority page, built, reviewed and shown on a call. You get working code you can click and resize, not a progress slide.

Inside Prism

Your engagement, week to week,
in one workspace.

Prism is the client workspace where your requests, approvals, tasks and weekly reviews live.

Some engagements include Prism, our client workspace, and your proposal says whether yours does. Where it does, your build runs in a workspace you log into: requests, approvals, the task list and the weekly review, beside the repository your team already owns.

  • 01

    Requests and approvals

    One queue, beside the repository your team owns.

  • 02

    Owned tasks

    Every task has one owner and a date.

  • 03

    Weekly review

    Each decision recorded, with the expectation attached.

Proof

A case study:
how reviews sped up delivery.

Brand panel: anonymised case study, multi-location healthcare, US, a delivery team inside an agency
Healthcare · US
Via agency partner · white-label

Multi-location healthcare: faster delivery through a steady process.

An agency handed its delivery queue to a dedicated team working under its brand, in its tools and templates. We sorted the backlog honestly and kept to a regular sprint schedule. QA ran before the agency saw any build. Delivery sped up 85%, all under the agency's brand.

Named work

Front-end developers,
inside a fund data company's team.

PixelCrayons provided frontend development support for our application and worked on the user interface with our team. Their developers were able to fit into the project and contribute where we needed additional technical capacity.

The front end is one part of a larger build. Each of the other parts is a service you can buy on its own, from the same senior team.

Where the design side of this work lives

This page covers building the screens. Want the same team to design and build them, so nothing is lost in the handover? That is design-to-code delivery. No designs yet? Our UI/UX design team makes them.

Checking your design files

What we flag in your design files
before we start building.

When we build from another team's files, our job is to match their design without quiet changes. So we check the files first. Anything that would force a guess during the build becomes a question before it starts.

What we find in the filesWhat we doWhy
Colours, type and spacingStore them once as variables in codeA design change is then made in one place, not fixed page by page across the site.
A component drawn without all its statesRaise the missing states as questionsWe agree every state before the build, so nobody has to guess.
A pattern that is impractical to buildFlag it before buildIt goes back to your designers as a question rather than being quietly changed in code.
Anything that would break the performance budgetBring you the trade-off as a decisionSpeed targets are agreed in writing before sprint one. You make the choice upfront and never find a slow page later.
What the files rarely show: keyboard use, focus states, screen-reader labels, calmer motionBuild them in to the WCAG 2.1 AA standard, checked in the browserAdding accessibility after launch costs more. Issues found in review are bugs, fixed in the same sprint.
Every page, once builtA written side-by-side check against the designsWe compare colours, spacing, type, states and motion, and fix any gaps within the agreed scope.

If you would rather one team design and build, that is our design-to-code service rather than this page.

Questions

Frequently
asked.

React is where we have the most engineers: React, Next.js and TypeScript. We also work in Vue and build themes for WordPress and Shopify. Your engineers will use your framework every week, and if we lack senior depth in one, we say so. We pick a framework your team can maintain and hire for, not the latest trend.

Yes, and our job is to build their design faithfully, without quiet changes. We check the files first. Missing states, or anything that would slow the page, become questions before we build. Every build ends with a written side-by-side check against the designs. If you'd rather one team designs and builds, that's our design-to-code service.

No. Scores change with content, third-party scripts and hosting we may not control. Instead, we agree page-size and Core Web Vitals targets in writing before the first sprint. We measure them on every release, on slowed-down connections and everyday phones. If a feature would break a target, we bring you the choice first.

As a build requirement with clear pass marks. WCAG 2.1 AA is our default standard. We check page structure, keyboard use, focus states, screen-reader labels, colour contrast and calmer motion options in the browser as we build. Accessibility issues found in review are bugs, fixed in the same sprint. We don't sell an extra audit of our own new code.

Your materials, data and accounts remain yours. Agreed ownership rights in bespoke deliverables transfer under the engagement terms and applicable payment; third-party software and assets keep their licences. We do not withhold customer-owned data or accounts over a payment dispute. Open-source dependencies keep their standard licences, documented in the handover notes.

Yes. Plenty of studios use us as their frontend development agency, under an NDA. You keep your project tools and your client calls; our engineers work behind the scenes. We don't approach the clients you introduce to us for direct business, through the work and for twelve months after the last assignment for that client ends, and it's written into the agreement.

The range

What it costs,
at the direct rate.

A fixed quote for the building blocks (components) and the pages made from them, priced by how many there are. Then a per-page rate once the library exists, and a retainer for adding pages after launch.

  • ProjectFront-end build$3,750–$25Kfixed quote, one-time
  • Per unitPage build$200–$1,000per page
  • RetainerEngineering retainer$1,875–$10Kper month
