Custom & Headless Development
Advanced website architectures, API-driven systems, and custom functionality for organizations with specialized requirements.
What This Service Covers
Effect Web Agency provides custom development for organizations that need capabilities beyond standard website platforms. This includes building custom front-end experiences, integrating APIs, and implementing headless systems that separate the content layer from the user interface. These solutions are designed to support flexibility, performance, and long-term scalability.
Custom development is appropriate for organizations with requirements that do not fit within traditional WordPress or Shopify structures.
What is Custom / Headless Development?
Custom Development
Custom development involves creating features, components, or system logic that are unique to an organization’s goals. This may include interactive elements, advanced data handling, integrations, or specialized front-end behavior.
Headless Development
Headless development separates the content management system from the visual interface. Content is delivered through an API, allowing the front-end to be completely custom and optimized for speed, design, or multi-channel delivery.
Headless architecture is used when organizations want complete control over the user experience while retaining a content management system behind the scenes. This decoupled approach enables delivering the duplicate content across websites, digital signage, kiosks, and future channels without rebuilding the system.



When Custom or Headless Development Makes Sense
Organizations typically choose custom or headless development when they need:
- More flexibility than WordPress or Shopify allows
- A highly customized user interface
- Integration with external systems
- API-driven features
- Advanced filtering, data display, or interactive components
- Faster front-end performance
- Multi-channel publishing (e.g., website + kiosk + internal dashboard)
- A long-term foundation built for scalability
This approach supports projects where structure or functionality cannot be achieved through standard CMS tools.
