  3. 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 | 2025-02-18

    Looks 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!
