Case Studies
Real results from real clients. See how we helped teams cut digital carbon while boosting speed and sales.
Green Lark
Challenge
An environmental consultancy on a slow, US-hosted Wix site with a carbon grade of C — the website contradicted the sustainability they sell to clients.
Solution
A hand-coded static rebuild on UK green hosting, with live per-page carbon measurement, consent-gated cookie-free analytics, clean URLs, WCAG 2.2 AA, and a public "Digital Footprint" audit page.

ActNow Consulting
Challenge
A certified B Corp consultancy needed a website that met the same standards they ask of clients — WCAG AAA accessibility, B Corp JEDI compliance, minimal carbon, and every claim backed by verifiable audit data.
Solution
Hand-coded static site with a dual-content AA/AAA toggle, build-time readability audits, pre-computed 7:1 contrast tokens, VoiceOver-tested navigation, and full WCAG 2.2 compliance documentation covering all 86 criteria.

Swynx
Challenge
We built Swynx as its own company. It is a privacy-first dead code scanner that uses graph analysis across 26 languages. The key rule: your code never leaves your machine.
Solution
A hand-coded 126-page site with SEO-driven pages for each language, framework comparisons, and use-case content. Plus the scanner tool itself. All built by OYNK.

The Greener Earth Project
Challenge
GEP sent impact reports by email. Donations were handled offline. There was no single place for supporters to see the real-world effect of their giving.
Solution
A full impact tracking platform with an interactive 3D globe, CO2e capture modelling, branded reports, and a full admin panel. Built with React, Supabase, and Mapbox GL.

Unyte Group
Challenge
A green construction firm selling carbon-cutting materials like biochar and hemp had a website that worked against their mission. It was heavy, slow, and used too much energy per visit.
Solution
A full green web redesign with clean code, light assets, and green hosting. Now their website matches their values.

"For every 1,000 page loads, our website now saves over 1KG of CO₂e—equivalent to driving nearly 4 miles in an average petrol car."

The Wild Moon Company
Challenge
A growing holistic crystal brand stuck on a generic, US-hosted Wix site that gave the founder little control and didn't reflect the care of her work.
Solution
A hand-built Astro site with its own typographic identity, a Keystatic CMS she edits herself, a migrated journal, an events map, a privacy-first contact relay, and live per-page carbon measurement — UK green-hosted and built to WCAG 2.2 AA.

A&P Resin
Challenge
A Daventry resin surfacing installer doing premium work, stuck on a single thin Google Sites page with no room to show their jobs and no presence in local search.
Solution
A 12-page hand-coded site under 10KB of CSS and JS, an image-led gallery of 28 real jobs, a guideline estimate tool, and local SEO — making the environmental case for permeable resin along the way.
