Sounds like the goal is to bundle up Bun with Claude Code insanely tightly, to the point where it doesn't matter if you have nodejs installed locally, but also they can optimize key things for Claude Code's Bun runtime as needed. It's a brilliant acquisition, and bun stays open source, which allows it to continue to grow, to Anthropics benefit and everyone else's.

#122Quote from the CEO of Anthropic in March 2025:
"I think we'll be there in three to six months where AI is writing 90% of the code and then in 12 months we may be in a world where AI is writing essentially all of the code"

#124Wouldn’t it make more sense to write the same functionality using a more performant, no-gc language? Aren’t competitors praised for their CLIs being faster for that reason?
Codex is written in Rust

Re: Anthropic acquires Bun
#126This decision is honestly very confusing to me as a constant user of Claude Code (I have 3 of them open at the moment.) So many of the issues with it seem to be because ... they wrote the damn thing in JavaScript? Claude is pretty good at a constrained task with tests -- couldn't you just port it to a different language? With Claude? And then just ... the huge claude.json which gets written on every message, like ...…
Boggles the mind.

#127No strategic roadmap is ever going to tell you: "Build a $0-revenue JavaScript runtime and one day an AI company will acquire you"

#128Earlier quoted context omitted.
No, they're clearly acquiring the technology. They're betting Claude Code on Bun, they have an invested interest in the health of Bun.
Why would they want to bet on nascent technology whereas Node.js bas existed for a god 15 years?
Because they needed something that could produce a single binary that works on every platform. They started shipping Claude Code with Bun back in July: https://x.com/jarredsumner/status/1943492457506697482

#129As someone who have been using Deno for the last few years, is there anything that Bun does better? Bun seems to use a different runtime (JSC) which is less tested than V8, which makes me assume it might perform worse in real-world tasks (maybe not anymore?). The last time I checked Bun's source code, it was... quite messy and spaghetti-like, plus Zig doesn't really offer many safety features, so it's not that hard t…
I haven't used Deno, but I do use Bun purely as a replacement for npm. It does the hard-linking thing that seems to be increasingly common for package managers these days (i.e. it populates your local node_modules with a bunch of hard links to its systemwide cache), which makes it vastly quicker and more disk-efficient than npm for most usage. Even with a cold cache, `bun install` with a large-ish dependency graph is…
pnpm does all that on top of node. Also disables postinstall scripts by default, making the recent security incidents we've seen a non-issue.

I had memory leaks in bun and not in deno or node for the same code. ymmv
