I work on Bun, and this post is confusing to me. Me personally and the Bun team continues to dogfood & make Bun better everyday. Our development pace has only gotten faster. Bun's stability has improved significantly since joining Anthropic.

Here are some things shipping in the next version of Bun:

- 17 MB smaller Windows x64 binaries [0]

- 8 MB smaller Linux binaries [1]

- `--no-orphans` CLI flag to recursively kill any lingering processes spawned [3]

- SSL context caching for client TCP & unix sockets, which significantly reduces memory usage for database clients like Mongoose/MongoDB [4]

- Experimental HTTP/3 & HTTP/2 client in fetch [5]

- Experimental HTTP/3 support in Bun.serve() [6]

- Bun.Image, a builtin image processing library [7]

(Along with several reliability improvements to node:fs, Worker, BroadcastChannel, and MessagePort)

The Anthropic acquisition also means Bun no longer needs to become a revenue-generating business. We are very incentivized to make Bun better because Claude Code depends on it, and so many software engineers depend on Claude Code to help get their work done.

Acquisitions in this industry tend to lead to a certain inevitable conclusion. The software that has been acquired gets worse as the original team members cash out and their culture is replaced with the culture of the new owner.

Perhaps Bun will be the exception, but you can't say that the concern is unfounded.

The CEO of Anthropic has a habit of making outlandish predictions about how AI is so very close to replacing human programmers. Anthropic has been applying this belief to Claude Code and it has become a giant heap of unmaintainable spaghetti.

Hasn't your team shrunk a lot? Word on the street is that many of Bun's employees left or let go in the time leading up to the acquisition. How many people are left working on Bun?

Has development velocity increased because you are merging large quantities of unreviewed LLM generated code? If so, I would be very worried about future stability if I used Bun.

Saying that you “work on Bun” is such a radical understatement. I have my reservations about Anthropic, but I don’t see how Bun could go wrong with you at the helm. And I’m sure that you are putting the stability and funding of a larger organization to good use :)

I’ve been a Bun maximalist since the beginning. Thank you Jarred!!!

		Perhaps it could go wrong because he uses AI robots to generate responses to issues on claude code that are also generated by AI robots? Just bots talking to each other like moltbook. It shows a level of AI maximalism that is absurd, concerning, and funny. But probably par for the course for someone working at Anthropic. I can imagine being surrounded by people doing similarly foolish things only encourages the foolery.

The best feature Bun delivered recently is portable binary. That portability is a huge deal to me as my users are often on ancient Linux distros. Thank you. Both node and deno require recent Linux, more exactly, recent glibc.
