App & website development agency in Brussels

Kodex Production is a mobile app and website development agency based in Brussels, working with businesses, independents and brands across Belgium and France. Fully custom work, one clear point of contact, and solutions that truly belong to you, with no commission and no mandatory subscription.

An agency based in Brussels, not a distant contractor

Our office is on Avenue de la Renaissance, in the European Quarter, 1000 Brussels. A salon in Ixelles, a restaurant in Saint-Gilles, a practice in Woluwe, a shop in Schaerbeek or an independent in Uccle: you get a team that's easy to reach, that can meet you on site, and that knows the Brussels business landscape. We also work with businesses in Liège, Charleroi, Namur, Antwerp and Ghent, as well as in France.

What we build for Brussels businesses

• Custom mobile apps (iOS, Android and installable PWA)
• Websites: showcase sites, e-commerce, online booking
• Digital communication: visual identity, content, online presence

Built around your trade

Every business has its own way of working. We build the app that matches yours, with the features that genuinely matter to your customers:

• Hair salon and barbershop: booking, loyalty, automatic reminders
• Restaurant: ordering, click and collect, table booking
• Beauty salon and spa: appointment booking, treatments, loyalty
• Personal trainers and gyms: sessions, tracking, memberships
• Dental and medical practices: appointments, reminders, patient tracking
• Real estate agency: property listings, alerts, viewings
• Shops and e-commerce: catalogue, payment, loyalty

Projects already delivered from Brussels

We don't show mockups, we show apps in production. Reset Laser, an auriculotherapy platform deployed across several countries, with appointment booking, treatment tracking, a conversational assistant and a multi-centre back office, as a native iOS app and a multilingual PWA. Turk's Barber Shop, a booking and loyalty app for a barbershop, with a customer account, a digital loyalty card and an admin dashboard. Publishing included, from the store listing to Apple's approval.
