uv is much much faster, but has substantially the same feature set as poetry.

Yeah. There was a wave of "rebuild it in Rust" companies and my complaint with all of them is that they became largely from-spec reimplementations of existing tools with little imagination of their own. The Rust projects are a fraction of the age of the scripted ones and they already feel ossified.

I'm not just talking about Astral here, I'm talking about the JS equivalents too like Biome and VoidZero which basically took the existing ossified architectures and made them gospel -_-

		That's not a good interpretation of Astral and uv. uv is way more than a rewrite in Rust of Poetry or pip - it has a metric ton of smart design decisions that are independent of the language it was written in, both in terms of what it does and how it speeds things up under the hood. https://nesbitt.io/2025/12/26/how-uv-got-so-fast.html is a useful review of some of the architectural tricks they came up with.
