Software development & IT services from Germany
We build web applications, websites and apps and run the IT behind them, from the first prototype to secure day-to-day operation. You work directly with the people who build your software, in English or German.
Services
From the first idea to day-to-day operation: we handle development, hosting and support so you can focus on your business.
Custom web applications, internal tools and integrations, built around the way your business actually works.
Company websites and landing pages that load fast, are easy to find and make it simple for visitors to get in touch.
Mobile apps for Android and iOS plus desktop applications, from the team behind Better Window Switcher and Krace.
AI assistants, document processing and automated workflows, built into the tools you already use, with privacy designed in.
Hosting, email, backups, hardware and security systems for small businesses, set up and supported by people who know your systems.
Sound decisions on technology, architecture, modernization and budget, with advice from people who build software themselves.
Returning client
Ongoing IT support for a quartz sand works: security cameras, truck scale weighing software, laptops, hosting and, most recently, a motion-rich website.
What we look after for the works
Our products
We develop our products with the same care as client projects. It keeps our skills sharp and shows what we can do, from a native Mac app to an Android app.
macOS 14 or later · native Swift
Every window and browser tab in 3D, one shortcut away.
Better Window Switcher replaces the macOS app switcher. Every open window and browser tab appears as a 3D card, and a few keystrokes take you straight to the one you need. Built natively in Swift, notarized by Apple, no account required, one-time purchase. More than 800 downloads since launch.
Launching 2026 
Android · native Kotlin
Know the road. Feel the drive.
Krace reads the road ahead and calls every corner out loud in rally style, timed to the speed you are actually driving. Plan routes in the app or import them from GPX files and Google Maps, then drive them offline on GPS alone.

About us
KSK IT was founded in 2024 in Mülheim an der Ruhr, Germany. You will not talk to a sales team, but to the engineers themselves: from the database and the app to the server in your office.
