Business web applications
Back offices, dashboards and internal tools that replace spreadsheets and manual work.
Custom Web and Mobile App Development in Luxembourg
When off-the-shelf software no longer fits your processes, a custom application does exactly what your business needs: a client portal, a mobile app for your customers, an internal tool for your teams or a full SaaS platform.
Kolot designs and develops web and mobile applications for businesses in Luxembourg, from the first mock-up to publication in the app stores and ongoing maintenance.
Applications we develop
Every application starts from your users and your processes:
Mobile apps for iOS and Android
Apps for your customers or field teams, native or cross-platform depending on your needs.
SaaS platforms
Multi-client platforms with subscriptions, user roles and an admin area.
Client portals and intranets
Secure spaces where clients or employees find documents, orders and requests.
Fintech and trading applications
Trading interfaces, analytics and payment flows, based on our experience with trading and blockchain products.
APIs and integrations
Connections to your CRM, ERP, payment providers and third-party services.
Web app, mobile app or both?
A web application runs in the browser on any device, with no installation. It is usually the fastest way to launch and the easiest to update. A mobile app published on the App Store and Google Play gives access to notifications, the camera, location and offline use, and stays on your users’ home screen.
Many projects start with a web application, or a progressive web app (PWA) that works like an app on mobile, and add native apps once usage is proven. We help you choose based on your users, budget and timeline, not on technology preferences.
