A lot of people seem confused about this acquisition because they think of Bun as a node.js compatible bundler / runtime and just compare it to Deno / npm. But I think its a really smart move if you think of where Bun has been pushing into lately which is a kind of cloud-native self contained runtime (S3 API, SQL, streaming, etc). For an agent like Claude Code this trajectory is really interesting as you are creating…

#472> At the time of writing, Bun's monthly downloads grew 25% last month (October, 2025), passing 7.2 million monthly downloads. We had over 4 years of runway to figure out monetization. We didn't have to join Anthropic. I believe this completely. They didn't have to join, which means they got a solid valuation. > Instead of putting our users & community through "Bun, the VC-backed startups tries to figure out monetizat…

Weird, AI writes terrible code for me that would never pass a code review. I guess people have different standards for good code.
I suspect you do not know how to use AI for writing code. No offence intended - it is a journey for everyone. You have to be setup with the right agentic coding tool, agent rules, agent tools (MCP servers), dynamic context acquisition and workflow (working with the agent operate from a plan rather than simple prompting and hoping for the best). But if you're lazy, don't put the effort in to understand what you're wor…

#474Considering that 1) Bun is written in Zig, 2) Zig has a strict no-AI policy [1], and 3) Bun has joined Claude, it seems that Bun and Zig are increasingly culturally apart. [1] https://ziglang.org/code-of-conduct/#strict-no-llm-no-ai-pol...

I'm sort of surprised to see that you used Claude Code so much. I had a vague idea that "Zig people" were generally "Software You Can Love" or "Handmade Software Movement" types, about small programs, exquisitely hand-written, etc, etc. And I know Bun started with an extreme attention to detail around performance. I would have thought LLM-generated code would run a bit counter to both of those. I had sort of carved t…
I am not your target with this question (I don't write Zig) but there is a spectrum of LLM usage for coding. It is possible to use LLMs extensively but almost never ship LLM generated code, except for tiny trivial functions. One can use them for ideation, quick research, or prototypes/starting places, and then build on that. That is how I use them, anyway Culturally I see pure vibe coders as intersecting more with en…
putting everyone using the generated outputs into a sort of unofficial grey market: even when using first-party tools. Which is weird.
Re: Anthropic acquires Bun
#477I wonder what this means for Deno. Will this make it more or less likely for people to use Bun vs Deno? And now that Bun doesn't need to run a profitable cloud company will they move faster and get ahead of Deno?
I think Deno's management have been somewhat distracted by their ongoing lawsuits with Oracle over the release of the Javascript trademark. I started out with Deno and when I discovered Bun, I pivoted. Personally I don't need the NodeJS/NPM compatability. Wish there was a Bun-lite which was freed of the backward compatability.
I use Hono, Zod, and Drizzle which AFAIK don't need Node compat.
IIRC I've only used Node compat once to delete a folder recursively with rm.

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…
Deno does all that. Hell, yarn does too, or pnpm as the sibling mentioned.
