i feel like moves like this make it even harder for new open-source tools to break through. there's already evidence that LLMs are biased toward established tools in their training data (you can check it here https://amplifying.ai/research/claude-code-picks). when a dominant player acquires the most popular toolchain in an ecosystem, that bias only deepens. not because of any skewing, but because the acquired tools get more usage, more documentation, more community content. getting a new project into model weights at meaningful scale is already really hard. acquisitions like this make it even harder.

Interesting acquihire. I would have assumed MS would have snagged them (until their __layoffs__ last year). My gut is that this is more for Python expertise, and ruff/ty knowledge of linting code than uv...

I'm a heavy user and instructor of uv. I'm teaching a course next week that features uv and rough (as does my recent Effective Testing book).

Interesting to read the comments about looking for a change. Honestly, uv is so much better than anything else in the Python community right now. We've used projects sponsored by Meta (and other questionable companies) in the past. I'm going to continue enjoying uv while I can.

I hope OpenAI realizes they cannot buy developer goodwill.

Welp. Guess we just wait for the next package management tool to come around. Really thought uv was gonna be the one.

Good for Astral though I guess, they do great work. Just not optimistic this is gonna be good for python devs long term.

I'm confused as to what will happen to their platform product which was in closed beta - pyx. Since they no longer need to worry about money (I assume) they no longer need to chase after enterprise customers?

Would there be any interest in me fixing the bugs in Pyflow and getting it updated to install newer python versions? It's almost identical to uv in concept, but I haven't touched it in 6 years.

Astral has demonstrated that there is desire for this sort of "just works" thing, which I struggled with, and led me to abandoning it. (I.e.: "pip/venv/conda are fine, why do I want this?", despite my personal experience with those as high-friction)

After investing a bunch in converting my projects to, and evangelizing uv, I feel betrayed. I smell stability troubles ahead. Should've stuck to Conda.

This might not be bad as long as Astral is allowed to continue to work on improving ty, uv and ruff. I do worry about they'll get distracted by their Codex job duties though.

these (uv and bun) are not acquihires, they're acqui-rootaccess

That's unfortunate for the python community. I can understand the move by Astral team, but it's still difficult to accept it.
