Custom mobile app and website development in Paris

Kodex Production helps businesses, independents and brands in Paris and Île-de-France build their custom mobile app and website. A solution that truly belongs to you, at a fair price, with no commission and no mandatory subscription.

Your app, in your name, anywhere in Paris

A shop in Le Marais, an independent in Montmartre, a brand in La Défense: what they all need is a digital tool that reflects their business, not a ready-made template. We design custom apps and websites, built for your customers, in your colours, that you keep entirely. Digital has no borders: your app follows you wherever your customers are, in Paris and beyond.

What we build for Paris businesses

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