What we do

PixelCrayons provides front-end development services: React and modern UI engineering by one senior team. Design systems become tested, reusable component libraries, with accessibility and performance budgets built in and pixel accuracy verified against your design files. Senior review covers every merge. We work direct for brands and white-label for agencies.

In every front end

What UI engineering
actually includes.

01

Design-system implementation, not one-off screens

Your design files are translated systematically. Tokens (colours, type, spacing) become variables, each design component becomes a coded component with its states, and pages are assembled from tested parts. The result is a component library your team can extend. The next page is composed, not rebuilt, and a design change propagates once instead of being patched across the site.

Every build
02

Accessibility engineered in, not bolted on

Semantic markup, keyboard paths, visible focus states, screen-reader labels, reduced-motion alternatives and WCAG 2.1 AA contrast are build requirements checked in the browser. Retrofitting accessibility after launch costs more than building it in, and the users it serves are real. It ships as standard, not as an upsell line.

Included
03

Performance budgets, measured on real devices

Page-weight and Core Web Vitals budgets are agreed in writing before sprint one. They're measured on every release, on slow connections and mid-range phones, not office machines. If a feature would break the budget, the trade-off comes to you as a decision upfront, not as a slow page discovered later.

Every release
04

Senior review gates on every merge

Nothing reaches your main branch unreviewed. A second senior engineer signs off every pull request against a written standard: correctness, accessibility, maintainability. Review gates keep a component library coherent as it grows. The front end you inherit reads as if one careful author wrote it.

Every merge
05

Pixel accuracy, verified, and handed over

Every build ends with a documented parity review against the design files. Tokens, spacing, type, states and motion checked side by side, deviations fixed as part of the scope. Then it is handed over: repository in your accounts from day one, with IP and ownership terms agreed before work starts. Component documentation is maintained as we build, not promised at the end.

In writing
How it starts

From design files
to components on staging.

01
Start

Brief and access

We sign an NDA and look through the design files and target stack together: components, states, edge cases, who maintains it after launch.

02
Once the brief is complete

Itemised proposal

We confirm when the proposal arrives. It lists the component inventory, the stack reasoning and the performance and accessibility budgets, in what order and for how much.

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

Design tokens are extracted into code, the project is scaffolded in your repository, CI runs and a preview URL goes up.

05
On the date in your proposal

First deliverable

Core components and a priority page, built, reviewed and demoed on a call. Working code you can click and resize, not a slide about progress.

Inside Prism

Your engagement, week to week,
in one workspace.

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

Where the engagement includes it, your build runs in a Prism 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.

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: fast, because it was disciplined.

An agency handed its delivery queue to a dedicated team working under their brand, inside their tools and templates. The backlog was triaged honestly, the sprint cadence held, and QA ran before the agency ever saw a build. Delivery sped up 85%, all delivered under the agency's brand.

The rest of the build

One layer of the system,
linked to the others.

The front end is one discipline inside a larger build: every neighbouring layer is a service you can buy on its own, from the same accountable team.

Where the design side of this work lives

This page is the engineering of the interface. Want the same team to design and build it, so nothing decays in handoff? That is design-to-code delivery. No artboards yet? UI/UX design is where they're made.

The file audit

What we flag in your design files
before the first component.

Building from another team's files, the job is fidelity to their design, not quiet improvements. So the files are audited first, and anything that would force an improvised decision mid-build becomes a question before it.

Questions

Frequently
asked.

The React family is our deepest bench: React, Next.js and TypeScript, alongside Vue and platform theming for WordPress and Shopify. We staff engineers who work in your framework every week, and where we lack senior depth we say so. Framework choice is argued from what your team can maintain and hire for, not from fashion.

Yes, and the job is fidelity to their design, not quiet improvements. Files are audited first, so missing states and anything that would fight the performance budget are raised as questions before build. Every build ends with a documented parity review against the artboards. If you'd rather one team designs and builds, that's our design-to-code service.

No, because scores move with content, third-party scripts and infrastructure we may not control. We commit instead to page-weight and Core Web Vitals budgets agreed in writing before the first sprint, measured on every release on throttled connections and mid-range devices. If a feature would break the budget, you get the trade-off as a decision upfront.

As an engineering requirement with acceptance criteria. WCAG 2.1 AA is the default target: semantic markup, keyboard paths, visible focus states, screen-reader labels, colour contrast and reduced-motion alternatives, verified in the browser as features are built. Accessibility issues found in review are defects, fixed inside the sprint. We don't sell a bolt-on audit of our own fresh 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: your project tools, your client calls, our engineers behind the scenes, NDA-backed. 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 component system and the pages built from it, priced from the component inventory, a per-page rate once the library exists, and a retainer for the team that keeps composing pages after launch.
