The user interface has been entirely developed using immediate mode gui dear-imgui library, with the ImGui.NET wrapper. This allows for a fast and bloat free experience but, at the same time, harder customization for a task of this size, since the library isn't really suited to the development of end-user applications. On the other side, it's what I'm most familiar to work with.

DearPyGui
Dear PyGui: A fast and powerful Graphical User Interface Toolkit for Python with minimal dependencies
Project mention: Show HN: Scripton – Python IDE with Built-In Realtime Visualizations | news.ycombinator.com | 2025-02-18Looks beautiful so congratulation for the launch.
Not sure if today this is enough though without any kind of AI chat assistant. Trae [0] is based on VSCode and Jetbrains Fleet are good looking as well. Visualization is definitely a big plus but there is also alternative like using rerun [1] and dearpygui [2] or some VSCode plugins (Python Image Preview, AREPL for Python)- might be hard to compete with those free alternatives on a subscription model IMHO but good luck!

FTXUI
Features: - Functional style. Inspired by [1] and React - Simple and elegant syntax (in my opinion). - Support for UTF8 and fullwidth chars (→ 测试). - No dependencies. - Cross platform. Linux/mac (main target), Windows (experimental thanks to contributors), - WebAssembly. - Keyboard & mouse navigation. Operating systems: - linux emscripten - linux gcc - linux clang - windows msvc - mac clang
But then i'm an engineer and doing things in organize manner is what i am supposed to do. And one day i came to this repo FXTUI a fantastic C++ library for creating terminal user interfaces, so i started building tuisic.
