Trusted by Leaders in Industrial Automation


Your One-Stop Partner for Industrial Software

Maximize efficiency and cost savings with a single end-to-end technology for your entire IoT factory—covering design, development, and quality assurance across a spectrum of devices ranging from low-end microcontrollers to high-end MPUs, spanning from embedded to desktop and mobile.

Be it the SCADA systems in your control room, the PLCs controlling the factory machines, or the rugged tablets used by operators, Qt cross-platform capabilities enable seamless reuse of software components on any devices. This not only enhances quality and user experience but also contributes to cost efficiency and faster time-to-market. In the context of Industry 4.0, where connected devices communicate, exchange data, and automate processes, Qt serves as a comprehensive middleware solution. With APIs for networking, threading, database access, location, and more, Qt empowers you to build a fully connected factory from a single codebase.

High-Accuracy and High-Performance Tooling for Unparalleled Industrial IoT Applications

Build fast and accurate real-time industrial applications capable of efficiently handling multiple concurrent processes, huge data loads, and state-of-the-art graphics.

Industrial software applications need real-time control over complex decentralized processes involving large amounts of data from remote sensors and advanced 2D and 3D graphics. Qt’s architecture is designed with performance in mind and optimized for real-time applications, with tooling for multi-thread execution of concurrent processes, on-demand behavior, and memory management, to mention only a few. Qt’s optimized data structures enable handling large datasets and real-time graphics with unparalleled performance on embedded systems.


Empower Your Factory Operations by Unlocking Accessibility and Control

Tame the complexity of industrial IoT automation by means of flexible, easily customizable SCADA systems enabling real-time control of any machine from any location.

For the implementation of advanced SCADA systems, the Qt framework’s connectivity tooling and real-time graphics capabilities deliver intuitive, responsive, and effective UI applications enabling data-driven decision-making in the industrial process.  You can achieve the highest degree of automation and easy portability across devices, working environments, and functions with Qt's broad out-of-the-box support for connectivity with multiple platforms and devices (Qt Serial Bus), remote desktop accessibility (Qt WebAssembly), cloud and edge connectivity (Qt HTTP Server), and machine-to-machine interaction (Qt Serial Bus, Qt MQTT, Qt OPC UA, Qt GRPC).

Meet the Industry Standard of Quality, Safety, and Security

Create dependable Industrial IoT devices that can be operated in full safety and security, with or without wireless connectivity, through any type of input/output interface—including physical knobs and touch screens.

With its transparent, well-documented code development practices and continuous integration and testing process, the Qt code meets the highest requirements of reliability, resiliency, and functional safety—including possible adherence to the Safety Integrity Levels defined in IEC61508 or DO-178C. 

In terms of tooling, the Axivion code analyzer helps you comply with coding guidelines and safety requirements. The Qt Safe Renderer ensures that safety-critical information (e.g., alarms) is promptly displayed under any circumstances. Qt LTS releases deliver stable APIs, ensuring long-lasting competitiveness in the market.

Panasonic Avionics

Built with Qt

By using Qt (with C++ and QML), the developers at Panasonic Avionics are able to focus on the design and the usability of the interactive.

“We use Qt in a lot of different development aspects. For example, we use it for creating a certification application that's actually used to certify all the wiring of the aircraft before deployment. We also offer a wide range of different form factors... We want to be able to develop once and show it on everything.'”

Parker Hannifin

Built with Qt

The vision for starting the project was to reduce the number of displays in the machinery cabin and create an application-based product that would allow their customers to integrate several applications into one display.

“The wow-effect was there when you program with QML. It keeps on astonishing with it’s ease-of-use and efficiency. I got that feeling right in the beginning and it has even amplified along the way. QML has provided a solid base for our software.”
