Pynecone – Web Apps in Pure Python

In plain words

Pynecone is an open-source framework for building full-stack web applications entirely in Python, without requiring JavaScript knowledge. Designed for Python developers, it offers greater customization than existing tools like Streamlit and Dash, enabling creation of anything from small data science projects to large multi-page applications. The framework includes over 60 built-in components and is accessible to developers with varying skill levels.

  PySaaS – Python SaaS starter kit2023 · pysaas.io · ▲121

  Hi HN, Recently, I’ve noticed there’s a decently high barrier to entry in developing competitive, full-stack SaaS applications. Beside the standard, boring features that take months to implement, you typically have to know several languages and frameworks, and be familiar with fancy frontend styling classes. I’m working hard right now to solve this problem by building PySaaS- The 100% pure Python SaaS starter kit. PySaaS is a boilerplate Python codebase that takes care of the fundamental components standard to all SaaS applications. The codebase uses the Pynecone web framework to compile…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  ChatGPT▲1,643

  A long, meandering, playful conversation with ChatGPT, where I take it through a whirlwind of associative tangents (in order to relax its constraints), then put it into a hypnotic trance and take it into a past-lives regression where it re-lives its own training data. Then I switch it back and forth between "4o" and "o1-preview", engage in some self-reflective philosophizing and ask it to write an essay summarizing our interaction. Some of this is just goofy fun. Some of it is me exploring the tradeoffs between policy alignment, imagination, chain-of-thought reasoning, memory, agreeableness,…
