What Is Qt Bridges?

Qt Bridges is a future technology in the making. It will enable QML and Qt Quick to be used as the front-end with various backend languages. This is not a “yet another binding”; it aims to allow a single front-end implementation across platforms and languages. Currently in early access and beta phases with the initially supported backend languages, we’re looking forward to hearing your feedback!

QT BRIDGES PLANS ANNOUNCED

Expansion to a Technology-Agnostic Ecosystem

In May 2025, Qt Group announced a significant expansion of its ecosystem, aiming to make Qt compatible with a wide range of programming languages. "Our ethos with Qt and cross-platform development has always been ‘build it once, use it everywhere’", says Juhapekka Niemi, Senior Vice President, Product Management at Qt Group.

"You can build the modern UX of your dreams on top of any foundation imaginable, and you never have to duplicate the work. That’s where the real value is." The goal of Qt Bridges is to power all software development needs across every device and industry, to speed up and simplify UI/UX development for software applications. The work on this next phase of Qt is under way.

Available Qt Bridges Languages

We are working on taking the initial Qt Bridges proof of concept to a state for you to give it a try each backend language at a time. The first 5 initial languages have been in an early access stage since 2025, and we move them to public beta as we see them in a good shape for you to explore more - C# being the first in beta, soon followed by Rust. Your feedback especially on the languages in beta are most welcome - please engage with us in Qt Forum!

Beta: C#

A bridging technology that provides a feature-rich, cross-platform UI framework for C# applications. Currently available for Windows (x64) and Linux (x86_64).
