This year, we've focused on delivering critical security enhancements, rolling out powerful new features for organizations, improving the overall user experience for the millions of developers who rely on PyPI every day, and responding to a number of security incidents with transparency. But first, let's look at some numbers that illustrate the sheer scale of PyPI in 2025: More than 3.9 million new files published More than 130,000 new projects created 1.92 exabytes of total data transferred 2.56 trillion total requests served 81,000 requests per second on average These numbers are a testament to the continued growth and vibrancy of the Python community.
