Custom Shopify Themes · Bespoke Shopify Plus Builds
Bespoke Theme Development
A custom storefront built entirely around your brand.
We build Shopify and Shopify Plus themes from scratch – engineered for speed, clarity, and conversion.
Our developers write clean, modular Liquid and React code without unnecessary libraries or plugins, creating a flexible foundation that’s easy to scale.
Each build is performance-tested, accessible, and compliant with Shopify’s latest standards.
Headless Shopify Development · Hydrogen Framework
Headless and Hydrogen Builds
For brands ready to go beyond the limits of a theme.
We develop headless Shopify experiences powered by Shopify Hydrogen, React, and Next.js – giving you total freedom in design, performance, and integration.
Ideal for international or high-volume brands, our headless setups combine speed, scalability, and advanced UX control without compromising manageability.
Shopify API Integration · Custom App Development
API and Systems Integration
Seamless integration with your business systems.
Your store should work seamlessly with your wider tech stack.
We build custom API integrations for ERP, CRM, and PIM systems, automate workflows through Shopify Flow, and connect your apps through reliable middleware solutions.
The result: a unified commerce system that reduces manual work and improves data accuracy.
ADA / WCAG Accessibility · GDPR / PCI DSS Compliance
Accessibility, Compliance and Security
Compliance and accessibility built in – not added later.
Every Red Fox build is developed to meet global compliance standards.
We embed accessibility (WCAG 2.1 AA), data protection (GDPR), and transaction security (PCI DSS) directly into our code and testing process, protecting your brand and your users.
