Open source or open season?
Astral to Join OpenAI
OpenAI scoops Python’s favorite tools — fans hopeful, skeptics yell “corporate doom”
TLDR: Astral, makers of popular Python tools like Ruff and uv, is joining OpenAI’s Codex team while pledging to keep everything open-source. Developers are split: some welcome the resources and tighter AI integration, others fear corporate control will stall the tools they rely on and reshape Python’s future.
Astral — the team behind wildly popular Python tools like Ruff and uv — says it’s joining OpenAI’s Codex team to “make programming more productive,” and promises to keep building in the open. On paper, it’s a power-up: the tools already see hundreds of millions of downloads, and OpenAI says support for open-source will continue. But the comments? A full-on vibe clash. Some users are cautiously excited, picturing faster updates and tighter AI-assisted coding.
Others smell consolidation. After Anthropic snapped up Bun, multiple commenters called this a pattern of AI giants collecting dev-tool trophies, with one fan pleading that uv and ruff “don’t go down the path to doom.” Skeptics don’t buy the “just funding it” story — one flatly calls it “upsetting,” doubting Big AI’s altruism. The thread split into two camps: the “more resources, more stability” hopefuls vs. the “corporate takeover of the toolbox” crowd. Jokes flew about OpenAI building an “Infinity Gauntlet” of programming tools, while Python devs clutched their package managers like comfort blankets. Drama aside, everyone agrees on one thing: if these beloved tools stay fast, open, and independent-feeling, users will cheer. If not, prepare the pitchforks — and the migration guides.
