The screens, buttons and load times a visitor judges you on, built as a tested component system in React and modern frameworks, with accessibility and performance budgets agreed before sprint one. 2,500+ projects shipped since 2004.
First deliverable in 14 days · Budgets in writing · You own the code
PixelCrayons provides front-end development services: React and modern UI engineering by one senior team. Design systems are implemented as tested, reusable component libraries. Accessibility and performance budgets are engineered into the build rather than audited after it, and pixel accuracy is verified against your design files. First working deliverable within 14 days of NDA, senior review on every merge, and you own every line. Direct for brands, white-label for agencies.
Outcomes tied to real engagements, not averages.
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.
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.
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.
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 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 yours: repository in your accounts from day one, IP assigned in the contract. Component documentation is maintained as we build, not promised at the end.
We sign the NDA and walk the design files and target stack together: components, states, edge cases, who maintains it after launch.
An itemised, priced scope with the component inventory, the stack reasoned, and performance and accessibility budgets stated, before you commit to anything.
Design tokens extracted into code, the project scaffolded in your repository, CI running and a preview URL standing. You review real pages in a real browser.
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.
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.
One queue, beside the repository your team owns.
Every task has one owner and a date.
Each decision recorded, with the expectation attached.
An agency handed its delivery queue to a dedicated pod 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%, no client left, and the end client never saw a new logo.
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.
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 React family is our deepest bench: React, Next.js and TypeScript are what most of our front-end web development services ship on, alongside Vue and platform theming for WordPress and Shopify where that is what your stack runs. The rule: we staff engineers who work in your framework every week. Where we lack genuine senior depth we say so and point you elsewhere rather than learn on your budget. Framework choice itself is argued from your constraints, what your team can maintain and hire for, not from fashion.
Yes, working from another team's design files is a large share of front-end engagements, and the job is fidelity to their design, not quiet improvements. Files are audited first: missing states, impractical patterns and anything that would fight the performance budget get flagged as questions before build, not improvised during it. Every build ends with a documented parity review against the artboards. If you would rather one team design and build, that promise is our design-to-code service rather than this page.
No, and you should be wary of any front-end development company that does, because scores move with content, third-party scripts and infrastructure we may not control. What we commit to instead is stronger: page-weight and Core Web Vitals budgets agreed in writing before the first sprint. They're measured on every release on throttled connections and mid-range devices, with the measurements shown to you. If a requested feature would break the budget, you get the trade-off as a decision upfront, not a slow page as a surprise.
As an engineering requirement with acceptance criteria, not a statement of intent. WCAG 2.1 AA is the default target: semantic markup, full keyboard paths, visible focus states, screen-reader labels, real 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 like any other. What we do not do is sell a bolt-on 'accessibility audit' of our own fresh code. If we built it, it should have shipped accessible.
You do, from day one. The repository lives in your accounts, IP assignment is written into the contract, and the component library, its documentation and the build tooling all transfer with it. No licence-back clauses, no proprietary framework you can only maintain through us. Open-source dependencies keep their standard licences, documented in the handover notes. If you leave, you take everything and lose nothing. We would rather keep you on responsiveness than on lock-in.
Yes, front-end builds are among the most requested white-label services. Plenty of strong studios use us as their frontend development agency rather than carry an engineering bench of their own. Your project tools, your client calls, our engineers behind the scenes. NDA-backed, with a clause signed at the start that we never approach your clients, during the engagement or after it. The average partnership runs past two years. That is the measure that matters.
Tell us what you're building, or send the design files. You'll have an itemised proposal with budgets stated within 48 hours, and reviewed components on a preview URL within 14 days of the NDA.
