What We Build

Mobile-first websites, e-commerce, and custom apps for South African businesses

01

Mobile-First Web Development

Every project starts on a mobile screen. With 95% of South African internet users on mobile, we build from the smallest screen up — not the other way around. The result is websites that load fast on 3G, feel native to touch, and convert visitors into customers.

  • React, Next.js, Astro & Vue.js
  • Progressive Web Apps with offline support
  • Touch-optimized interfaces
  • API & third-party integrations

Performance & SEO

Speed is not a feature — it is the feature. A one-second delay in load time costs you 7% of conversions. We optimise every asset, every request, every render path so your site dominates both Google rankings and user experience.

  • Core Web Vitals optimization
  • Technical & local SEO
  • Schema markup & structured data
  • CDN setup & image optimization

E-Commerce & WhatsApp Integration

South Africans buy differently. WhatsApp is the storefront, mobile money is the checkout, and trust is built through direct conversation. We build e-commerce experiences that fit how your customers actually shop — not how Silicon Valley thinks they should.

  • Shopify & WooCommerce development
  • PayFast, Yoco & payment gateways
  • WhatsApp ordering & support flows
  • Inventory & order management

Custom Web Applications

Templates don't solve real problems. When your business needs software that fits your exact workflow — a client portal, an internal tool, an industry-specific platform — we build it from scratch. From engineering service platforms to agricultural traceability apps, every solution is shaped around how your business actually operates.

  • Custom dashboards & admin panels
  • Industry-specific platforms
  • Data-driven applications & APIs
  • Workflow automation tools

Hear from businesses that went from slow sites to real results

"Our old website took 8 seconds to load on mobile. DigiBannister rebuilt it in Astro and now it loads in under 2 seconds. Our online enquiries doubled within the first month."
TM
Thabo Molefe Managing Director, Greenline Logistics
"The WhatsApp ordering system they built changed everything for us. Customers place orders directly through chat, and our sales have grown 40% since launch. Best investment we've made."
SN
Sarah Naidoo Owner, Cape Craft Collective
"Duncan understood exactly what we needed — a custom platform our field technicians could use on their phones. The app works perfectly even in areas with poor signal. Truly mobile-first thinking."

About DigiBannister

Built for How South Africa
Actually Goes Online.

Most web agencies build for fast Wi-Fi and flagship phones. We build for the 3G connection in Limpopo, the shared Android in a township spaza shop, the load-shedding that kills your server mid-checkout. That is the reality we design for.

DigiBannister builds mobile-first solutions — from e-commerce stores with WhatsApp ordering to offline-capable apps for rural markets — that work in the conditions South African users actually face. If your site loads fast here, it flies everywhere else.

Mobile-First Philosophy

Every pixel designed for mobile screens first, then enhanced for desktop.

South African Focused

Optimized for local networks, payment gateways, and user behaviours.

Performance Obsessed

Lightning-fast loading even on 2G/3G networks with offline-first capabilities.
