- Project mention: Ask HN: What Toolchains Are People Using for Desktop App Development in 2025? | news.ycombinator.com | 2025-08-09
Because I mainly work with python, I am using Kivy (https://kivy.org/).
Earlier I was HTMX, Jinja templates, Flask, Tailwind and little vanilla JS. It was too inelegant for my taste.
I am considering moving to either Swift, or JS/Svelete

activitywatch
The best free and open-source automated time tracker. Cross-platform, extensible, privacy-focused.
Project mention: EFF Launches Age Verification Hub as Resource Against Misguided Laws | news.ycombinator.com | 2025-12-11Ah okay. I think this would probably be pretty tricky, security-wise, no? One of my first thoughts that might help would be writing a simple tool that parses history from your browsers to categorize it. Other than that, there are things like https://activitywatch.net/ (which seems to have a desktop and Android version)

electricitymaps-contrib
The open source repository for Electricity Maps App and data parsers that powers the world's most comprehensive electricity data platform
Project mention: Arctic sea ice sets a record low maximum in 2025 | news.ycombinator.com | 2025-03-27Don't know much about that policy but I frequently monitor electricity usage via https://app.electricitymaps.com and Germany has usually the highest carbon intensity electricity in western Europe. Getting rid of nuclear seems to have made things worse.
- Project mention: Show HN: Rio – Modern Web Apps in Pure Python, No JavaScript/HTML/CSS Needed | news.ycombinator.com | 2025-03-08
Hey HN,
Over the past 10 months, my friends and I created an open source project called Rio to help Python developers build modern web apps without needing HTML, CSS, or JavaScript. Whether you're working on a simple internal tool or a complex multi-page app, Rio lets you stay in the Python ecosystem without needing to learn frontend frameworks.
With Rio, the UI is defined using Python components, inspired by React and Flutter. Instead of writing HTML/CSS, you compose reusable UI elements in Python and let Rio handle rendering and state updates. The backend and frontend stay seamlessly connected using WebSockets, so data syncs automatically without manual API calls. Since Rio is fully Python-native, you can integrate it with any Python library, from data science tools to AI models.
Many Python projects rely on popular libraries like React internally, but the core benefits and elegance of these libraries are often diluted in the process. Unlike wrapper frameworks, Rio is built from scratch, offering a cleaner, faster, and more efficient development experience specifically for Python.
We’ve seen users build everything from CRM tools to dashboards, LLM interfaces, and interactive reports using Rio. If you’re a Python developer who has wanted a better way to build web apps without learning JavaScript, we’d love to hear your thoughts!

A guy in Brazil who coded up:
https://nodezator.com/
because it was the first Python node editor which "just worked" out of the box when I tried to run it.
Based on a game dev system which was called Indie Python, the main site is now at:

I kick in to Wikipedia via Microsoft Rewards points whenever they are matching points, or if I have a surplus of Amazon gift card money 'cause there haven't been any Kindle book sales I bought into for a while.
