#eurorust has always sold out since the first year and we have no intention to break the streak – get your ticket while they last (and before we switch to late bird pricing on Sep 1st or hold off until after to help us keep a balanced budget 💸)

Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry. We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".
