This argument doesn’t make much sense to me. Claude Code, like any product, presumably has dozens of external dependencies. What’s so special about Bun specifically that motivated an acquisition?

A dependency that forms the foundation of your build process, distribution mechanisms, and management of other dependencies is a materially different risk than a dependency that, say, colorizes terminal output.

I’m doubtful that alone motivated an acquisition, it was surely a confluence of factors, but Bun is definitely a significant dependency for Claude Code.

If they found themselves pushing PRs to bun that got ignored and they wanted to speed up priority on things they needed, if the acq was cheap enough, this is the way to do it.
