Project mention: Show HN: The Jawah Python Organization Was in GitHub Secure Open Source Fund | news.ycombinator.com | 2025-08-15already is! But we also fixed a lot of tiny security issues thanks to the sharp eyes of experts out there!
Now, there's another project we know is going to absolutely need the utmost standard of security. *Niquests!*
It's been seven months since our last update for the potential Requests replacement and we wanted to share some exciting news about it.
For those who did not know about it: Niquests is a drop-in replacement for the popular Requests http client. https://github.com/jawah/niquests
Here some anecdote I'd like to share with all of you:

Niquests is about to break the 1000th place on PyPI most downloaded packages! With around 55 thousands pull each day.

A significant effort was spent summarizing lengthy GitHub issues and unit test code. I used OpenAI API to summarize the text data to be even more efficient. For example, one GitHub issue (#1026) was condensed to capture its essence, highlighting key points about modal submissions, API errors, and the proper usage of ack() and client.views_update(). The summary retained important error messages, links to official documentation, and included a useful code snippet as well.
