Show HN: Pyra – a Python toolchain experiment inspired by uv and Bun

https://github.com/treyorr/pyra
4•trey-orr•2h ago
I’ve been working on Pyra for the past few months and wanted to start sharing it in public.

Right now it’s focused on the core package/project management workflow: Python installs, init, add/remove, lockfiles, env sync, and running commands in the managed env.

The bigger thing I’m exploring is whether Python could eventually support a more cohesive toolchain story overall, more in the direction of Bun: not just packaging, but maybe over time testing, tasks, notebooks, and other common workflow tools feeling like one system instead of a bunch of separate pieces.

It’s still early, and I’m definitely not claiming it’s as mature as uv. I’m mostly sharing it now because I want honest feedback on whether the direction feels interesting or misguided.

Serious question: what does Pyra do differently from uv? Both are Rust-based, both use pyproject.toml, both focus on determinism, and uv already owns mindshare here with Astral's funding behind it.

A "why not uv" section in the README would probably be the single highest-leverage thing you could add - otherwise every second commenter in this thread will ask the same question and the actual differentiator (if there is one) gets lost in noise
