What's Included

Everything you need to ship and scale.

A complete development service — from Figma to production — with the quality controls and handovers that let you grow confidently.

Custom Design System

Figma component library that maps 1:1 to production code. Every token, variant, and state documented and dev-ready from day one.

Performance Engineering

Core Web Vitals optimised for 95+ PageSpeed on every page. We treat performance as a feature, not an afterthought.

CMS Integration

Contentful, Sanity, or headless WordPress — you own your content. We configure a CMS that your team can actually use without developer help.

Accessibility

WCAG 2.1 AA compliance, keyboard navigation, and screen reader tested. We build for everyone, and document what we implement.

Deployment & Hosting

Vercel or Netlify CI/CD with automatic preview deployments for every PR. Your staging environment is always one URL away.

Post-Launch Support

60-day dedicated support window, full documentation, and a handover session. You won't be left guessing how anything works.

How It Works

Our process, from brief to launch.

Four clear phases, no surprises. You'll always know where we are and what comes next.

01

Discovery

We audit your existing setup, map your user journeys, and define technical requirements before a single wireframe is drawn. This phase prevents the expensive pivots that happen mid-build.

02

Design & Prototype

Figma designs across all breakpoints, reviewed in a shared workspace. You approve every detail before we write a line of code. No surprises, no rework.

03

Build & QA

Component-by-component development with automated tests, accessibility checks, and real-device testing at every milestone. We ship quality at every stage, not just at the end.

04

Launch & Handover

Deployment, DNS, performance verification, CMS training, and a 60-day support window. You leave with everything you need to manage and grow the site yourself.

Performance by Default

Every site ships at 95+ PageSpeed.

1.2s Largest Contentful Paint · Good = under 2.5s

How we achieve this consistently

  • Critical CSS inlined, render-blocking resources eliminated at build time
  • Hero images preloaded with fetchpriority="high"
  • Fonts served from CDN with font-display: optional
  • Edge hosting on Vercel — sub-50ms TTFB from every global region
0.01 Cumulative Layout Shift · Good = under 0.1

How we achieve this consistently

  • Every image has explicit width/height — no layout-shifting on load
  • Fonts use size-adjust to prevent text reflow on swap
  • Ads and embeds placed in reserved-space containers
  • All animations use transform/opacity only — zero layout properties
48ms Interaction to Next Paint · Good = under 200ms

How we achieve this consistently

  • Long tasks broken up with scheduler.yield()
  • Third-party scripts deferred until after first user interaction
  • Event handlers passive by default throughout
  • Heavy computations moved to Web Workers off the main thread
180ms Time to First Byte · Good = under 800ms

How we achieve this consistently

  • Static HTML served from the edge — no server round-trips
  • Incremental Static Regeneration for dynamic content
  • Aggressive Cache-Control headers with stale-while-revalidate
  • Database queries cached at CDN layer for instant repeat visits
97 PageSpeed Score (Mobile) · Target = 90+

How we achieve this consistently

  • All images as WebP/AVIF with responsive srcset and sizes attributes
  • JavaScript code-split per route, unused code tree-shaken away
  • Zero unused CSS in production via PostCSS purge
  • HTTP/3 + Brotli compression + proper caching on all static assets
Why Prism

Built different. Delivered different.

Abstract 3D shapes

One team, no handoffs

Your designer is your developer's colleague. There are no brief-to-brief translations, no gaps in context, and no blame games when something doesn't match.

Revenue-focused, not deliverable-focused

We don't close a project when we hand over the files. We measure success by whether it performs — faster load, better conversions, more qualified leads.

You own everything

Code, Figma files, domain, hosting, content — it's all yours. No proprietary systems, no lock-in, no monthly fees to keep the lights on.

We stay until it works

The 60-day post-launch window isn't a marketing line. We monitor, fix, and iterate until the site is performing the way we said it would.

See it in action

Real results from real clients.

We've built 180+ websites across every industry. Here are two that capture what we mean by high performance.
