Anthropic acquired Bun. Clearly, Bun is not a runtime for C++, Rust, or Python. For an engineering project, strongly typed TypeScript was basically the only possible choice for them.

Anthropic acquired Bun after making Claude Code.

I am not following your logic. Anthropic acquired Bun and so all of their end-user software should use it?

Or am I missing sarcasm?

Is Anthropic's acquisition of Bun alone still not enough to infer their tech stack? What more obvious signals would be needed?

Also, honestly, given the speed constraints of large models, it makes almost no difference what language an agent is written in. The small performance differences between programming languages do not even begin to matter compared with network latency, let alone the speed at which a large model streams tokens.

Why do you think they acquired Bun. To look at it?

Also you needed a leak to know that CC, that is out for 1 year, is in TS?

I don't know why they acquired Bun. Surely not because there's no other means to write command line programs.

What, are you shaming people for not being aware what (obfuscated) code some 1 year old software is written in?

So what do you think the obfuscated .js code in a 2026 engineering project was generated with? Nim?
