High-Performance Apps Built with Qt & C++
Qt Development Services
Qt is the world’s leading C++ framework for building high-performance, cross-platform applications — from desktop software and embedded systems to automotive HMIs and industrial control panels. We build Qt applications that run natively on Windows, macOS, Linux, Android, iOS, and embedded devices from a single C++/QML codebase. Qt powers products at Mercedes-Benz, LG, Bosch, Siemens, AMD, and thousands of companies worldwide. When you need raw speed, hardware-level access, and pixel-perfect UIs across every platform — Qt delivers.
Our Qt Development Services Include
We build high-performance applications using the Qt framework with C++ and QML. Qt gives you true native performance on Windows, macOS, Linux, Android, iOS, and embedded systems — all from one codebase. With Qt Widgets for traditional desktop UIs and Qt Quick/QML for modern, animated, touch-friendly interfaces, your app looks and feels native on every platform. Full access to hardware, multi-threading, networking, and OpenGL/Vulkan rendering.
Learn MoreWhat We Build For You with Qt
Qt is the industry standard for performance-critical, cross-platform applications. From desktop software and automotive dashboards to medical devices and factory control systems — Qt runs where other frameworks cannot. Here is what we build.
Cross-Platform Desktop Applications
We build Qt desktop applications that run natively on Windows, macOS, and Linux from a single C++ codebase. Using Qt Widgets for traditional business UIs or Qt Quick/QML for modern, animated interfaces, your app compiles to a true native binary on each platform — no virtual machine, no interpreter, no runtime. Qt apps launch instantly, use minimal memory, and access the full power of the operating system: file system, registry, multi-threading, networking, serial ports, and GPU rendering. We build data management tools, engineering software, creative applications, financial terminals, and enterprise productivity suites.
Embedded & IoT Applications
Qt is the leading framework for embedded systems and IoT devices. We build Qt applications for custom hardware running embedded Linux, Yocto, RTOS, and bare-metal systems. Your embedded UI renders smoothly on resource-constrained devices with as little as 256 MB RAM using Qt’s hardware-accelerated rendering pipeline (OpenGL ES, Vulkan). We build touchscreen interfaces for smart appliances, vending machines, medical devices, industrial HMIs, home automation panels, and kiosk systems. Qt’s Boot to Qt solution gets your device from power-on to your app in under 2 seconds.
Automotive & Industrial HMI
Mercedes-Benz, BMW, LG, and Bosch use Qt for their in-vehicle infotainment (IVI) and industrial HMI systems. We build automotive dashboard UIs, cluster displays, HVAC controls, and infotainment systems using Qt for MCUs, Qt Quick, and Qt Safe Renderer for safety-critical displays. For industrial environments, we build SCADA front-ends, PLC control panels, CNC machine interfaces, and factory floor monitoring dashboards that render at 60fps on industrial-grade hardware. Qt’s real-time rendering and C++ performance make it the only framework trusted for mission-critical, safety-certified applications.
Qt Quick / QML Modern UIs
Qt Quick and QML let you build fluid, animated, touch-friendly user interfaces that rival mobile app quality — on desktop and embedded devices alike. We design and develop custom QML components, animated transitions, particle effects, 3D scenes (Qt 3D), and responsive layouts that scale across screen sizes and input methods (mouse, touch, pen). QML is declarative and designer-friendly, while C++ handles the performance-critical backend logic. We build media players, dashboard UIs, creative tools, and interactive data visualizations with smooth 60fps animations and GPU-accelerated rendering.
High-Performance C++ Applications
When milliseconds matter, Qt + C++ delivers. We build performance-critical applications — real-time video/audio processing, scientific visualization, medical imaging, financial trading platforms, 3D rendering tools, and simulation software. C++ gives you direct memory control, SIMD optimization, multi-threaded execution, and GPU acceleration (OpenGL, Vulkan, CUDA). Qt provides the cross-platform abstraction, networking stack (TCP/UDP/WebSocket), database access (SQLite, PostgreSQL, MySQL, ODBC), and UI framework on top. Your app processes millions of data points per second while staying responsive and visually polished.
Legacy Qt Migration & Modernization
Still running a Qt 4 or early Qt 5 application? We migrate your codebase to Qt 6 — the latest version with improved performance, modern C++17/20 support, new graphics architecture (RHI for Vulkan/Metal/Direct3D), and long-term support. We audit your existing code, replace deprecated APIs, upgrade build systems to CMake, modernize QML components, and optimize for current hardware. We also migrate from Qt Widgets to Qt Quick/QML if you want a modern, animated UI. Your business logic stays intact, your app gets faster, and you are ready for the next decade of Qt support. Most migrations complete in 6–14 weeks.

Frequently Asked Questions
Got questions about Qt development? Here are simple, honest answers to what people ask us most.
What is Qt and what is it used for?
Qt (pronounced “cute”) is a powerful C++ framework for building cross-platform applications. It runs on Windows, macOS, Linux, Android, iOS, and embedded devices from a single codebase. Qt is used for desktop software, embedded UIs, automotive infotainment systems, industrial control panels, medical devices, and IoT products. Companies like Mercedes-Benz, LG, Bosch, Siemens, AMD, Autodesk, and VirtualBox use Qt. It offers two UI approaches: Qt Widgets (traditional desktop-style) and Qt Quick/QML (modern, animated, touch-friendly). Qt is open-source (LGPL/GPL) with a commercial license option for proprietary products.
How much does a custom Qt application cost?
A simple Qt desktop tool (utility app, data viewer, single-purpose tool) costs $15,000–$40,000. A mid-sized business application with database integration, networking, and custom UI runs $40,000–$100,000. A complex Qt application (industrial HMI, automotive dashboard, medical imaging software, embedded system UI) ranges from $100,000–$300,000+. Qt commercial licensing adds $3,000–$5,000 per developer per year (or you can use LGPL for free if your licensing allows it). Embedded and automotive projects tend to cost more due to hardware integration and certification requirements. We give you a detailed estimate after understanding your requirements.
Qt Widgets vs Qt Quick/QML — which should I use?
Qt Widgets is best for traditional desktop applications with menus, toolbars, tables, and forms — think data-heavy enterprise tools, IDE-style interfaces, and business management systems. It uses C++ for everything and has a mature, well-documented API. Qt Quick/QML is best for modern, animated, touch-friendly UIs — think automotive dashboards, embedded touchscreens, media players, and consumer-facing apps. QML is declarative (like HTML/CSS for desktop) and ideal for designers. You can mix both in the same application. For most new projects, we recommend Qt Quick for the UI with C++ for the backend logic.
Can Qt apps run on embedded devices and IoT hardware?
Yes — this is one of Qt’s biggest strengths. Qt runs on embedded Linux, Yocto, RTOS (FreeRTOS, VxWorks), and even bare-metal microcontrollers (Qt for MCUs). It supports ARM, MIPS, x86, and RISC-V architectures. Qt’s hardware-accelerated rendering works on devices with as little as 256 MB RAM and basic GPU support (OpenGL ES 2.0+). Qt’s Boot to Qt provides a pre-built embedded Linux image that boots directly into your Qt application in under 2 seconds. We build UIs for smart appliances, medical monitors, industrial touchscreens, vending machines, kiosks, and custom IoT devices.
How long does it take to build a Qt application?
A simple Qt desktop tool takes 6–10 weeks. A mid-sized cross-platform application with database integration, networking, and custom UI takes 10–20 weeks. A complex embedded or industrial Qt application with hardware integration, real-time data processing, and certification requirements takes 4–10 months. Migrating from Qt 4/5 to Qt 6 takes 6–14 weeks. C++ development takes longer than JavaScript or Python, but you get unmatched performance, lower resource usage, and apps that run on platforms where web-based frameworks simply cannot. We work in 2-week sprints with regular builds.
Qt vs Electron vs .NET — which is best for desktop apps?
Choose Qt if: you need maximum performance (C++ speed), your app runs on embedded devices or custom hardware, you need true cross-platform support (Windows + macOS + Linux + embedded + mobile), or your industry requires safety certification (automotive, medical, industrial). Choose Electron if: your team is web-focused (JavaScript/TypeScript) and performance is not critical. Choose .NET/WPF if: you are Windows-only and your team knows C#. Qt is the only framework that scales from a 256 MB embedded device to a multi-monitor desktop workstation. For performance-critical, hardware-integrated, or cross-platform industrial apps, Qt has no equal. We advise you based on your specific needs.
