marimo
Transform data, train models, and run SQL with marimo — feels like a next-gen reactive notebook, stored as Git-friendly Python. Deploy as scripts, pipelines, endpoints, and apps. All from an AI-native editor (or your own).
Project mention: Show HN: OverType – A Markdown WYSIWYG editor that's just a textarea | news.ycombinator.com | 2025-08-17I thought it should be extremely portable ("everything just works, it's native"), but it doesn't work on iOS 9.3.6. It doesn't even let me input text into the textarea...
A natural extension seems to be a source code editor with syntax highlighting, like those used in https://marimo.io/, Jupyter, https://plutojl.org/ and other notebook-like Web editors.

I thought that using Makefile targets was the shortest friendliest to show what a project can do. Turns out make and Makefiles can be mysterious when they fail.
Tutorials are "best-effort" and often don't dwell on the rabbit-holes they create when a poor soul runs astray of the sunny path.
Example of a good tutorial:
Python's powerline shell: https://github.com/b-ryan/powerline-shell
The README is succinct. Well put together.

LitServe
The easiest way to deploy agents, MCP servers, models, RAG, pipelines and more. No MLOps. No YAML.
I came across the LitServe API and was pleasantly curious to try it out for this particular project. While it can be easily achieved manually using FastAPI and Uvicorn, LitServe API (also uses the same under the hood!) has a lot of "batteries-included" approach that seems to reduce a lot of the boilerplate code.

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!
