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

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

I have seen the comments, maybe you could provide a real use case that we maybe did not think about.

Not clear what problem this is solving that uv and bun don’t already solve? This is like a solution looking for a problem.

If you enjoyed and learned from it I guess that’s what really matters.

Ah yes, the "big bang" commit.

Does it actually do anything different, or did you learn anything along the way?
