See what your Python app sends and receives over HTTP
Hi, A few months ago, I shared a tool I built for personal use to easily trace HTTP client requests in any Python app. It links requests to the corresponding Python code and comes with a nice UI. By easily, I mean: no external dependencies, no setup, no superuser rights, and no code modifications — just do "pip install httpdbg" and then launch your code using the "pyhttpdbg" command. That’s it. I received a lot of positive feedback — not just here, but also on social media, in podcasts, and beyond. So, thank you! Since I last introduced httpdbg, I’ve made many improvements — based on both my…

What it does
httpdbg is a tool to trace the HTTP(S) client requests in your python code.
httpdbg is a tool for tracing HTTP requests in your Python code for debugging purposes. pip install httpdbg Then, replace the python command with pyhttpdbg to execute your code. pyhttpdbg -m pytest -v examples/ httpdbg is not ... httpdbg isn’t just another proxy. It can: httpdbg is not a monitoring tool. It should not be used in production code, but only for debugging purposes. httpdbg supports HTTP/1.0 , HTTP/1.1 and HTTP/2 . For HTTP/2 , it only traces requests made with the h2 package. Theorically, all pure python HTTP requests are fully traceable by httpdbgfrom httpdbg.readthedocs.io

Httpdbg – A tool to trace the HTTP requests sent by your Python code2024 · github.com · ▲200Hi, I created httpdbg, a tool for Python developers to easily debug HTTP(S) client requests in Python programs. I developed it because I needed a tool that could help me trace the HTTP requests sent by my tests back to the corresponding methods in our API client. The goal of this tool is to simplify the debugging process, so I designed it to be as simple as possible. It requires no external dependencies, no setup, no superuser privileges, and no code modifications. I'm sharing it with you today because I use it regularly, and it seems like others have found it useful too—so it might be…

Talanoa▲346Hi 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…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
