DearPyGui
Dear PyGui: A fast and powerful Graphical User Interface Toolkit for Python with minimal dependencies
Project mention: Show HN: Scripton β 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!

webview
Tiny cross-platform webview library for C/C++. Uses WebKit (GTK/Cocoa) and Edge WebView2 (Windows).
Project mention: Show HN: Vaev β A browser engine built from scratch (It renders google.com) | news.ycombinator.com | 2025-05-18What do you mean by that? WebView is just Chrome embedded inside of an Android app. Same thing already exists on Windows (Edge WebView2), macOS (WKWebView) and Linux (WebKitGTK). There's also a library that wraps all of them into a single interface:
https://github.com/webview/webview
The entire point of WebView is that it's a browser embedded inside of a different application, how do you expect it to be a "standalone project"?

Project mention: App Should Have Been a Website (and Probably Your Game Too) | news.ycombinator.com | 2024-12-31
Hi there! Yes, I will switch to a more distinctive icon in the future once I can afford to hire a new designer.
Multiplayer was quoting the correct reason. I also exeplained more about the timeline here: https://github.com/nuttyartist/notes/issues/690#issuecomment...
Tldr: The FOSS version earned a stable revenue through Google Ads placed on the website, since the website ranked high on Google searches. Two years ago, that changed since the website got de-ranked, so I created a different, proprietary version of the app based on the FOSS version but with a totally revamped block editor that I wrote from scratch - that I worked on full-time for a whole 1 year.

QRhi is pretty much the exact same goal than pygfx with a different implementation: https://github.com/qt/qtbase/tree/dev/src/gui/rhi
I've been using it for 4-ish years now in https://ossia.io
