Hi Erik, I’m currently moving from Qt to [Slint UI](https://slint.dev/) and for long term also move away from C++ towards Rust.

Thanks for the suggestion, but to be honest, Tcl/Tk and FreeBasic are not interesting for us. LibrePCB is a giant software project with very specific needs. The chosen language and GUI toolkit is a fundamental decision which will have significant impact on the project’s future and thus have to be evaluated very seriously, based on many technical aspects but also considering the future of these toolkits. Some examples: - LibrePCB is the result of ~12 years of development. Switching the language has to be done step by step and will probably take more than 10 years to complete. During this time, it must be possible to mix the old with the new language so we require high compatibility between them. - Even just the _evaluation_ of a new GUI toolkit took me several weeks because it is so complex. - I estimate _at least_ 6 months of full-time work for migrating the _major_ part of LibrePCB to a new UI. Migrating the whole UI will take several years. - Given these time frames, we require toolkits with a bright future. Although I do like old & mature toolkits, most of them will die sooner or later because modern toolkits provide a lot of advantages and will replace them step by step. ---

Qt, for most of its history — the whole codebase was built on it going back to the early days. That said, if you’re looking at anything post-1.x, there’s a meaningful wrinkle with what they did in 2.0 that changes the answer a bit. Did a longer breakdown of the Qt roots and the newer framework layer here: [LibrePCB GUI Framework: From Qt to Slint in Version 2.0 - Port & Patch](https://portandpatch.com/uncategorized/librepcb-gui-framework-qt-slint/)
