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…

Handmade Cities founder here. We never associated with Bun other than extending an invitation to rent a job booth at a conference: this was years ago when I had a Twitter account, so it's fair if Jarred doesn't remember. If Handmade Cities had the opportunity to collaborate with Bun today, we would not take it, even prior to this acquisition. HMC wants to level up systems while remaining performant, snappy and butter…

I'm pretty sure the GP was referring to https://handmade.network as their manifesto made multiple rounds here, was discussed at length and far more obviously related to "handmade movement" remark than your org.

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…

I'm also confused.. Why does a generic AI company that helps coding as one of main offering get deeply in bed with one tech stack

I mean would it have made sense to acquire golang if it were on sale?

There’s like 100x more JS developers than C# developers. JS can also run code very quickly, where with an AOT language, you need to AOT compile it. For tool calls, eval-as-a-service, running in browser JS is far ahead of C#.

So, everyone who can hack some JS is now a developer? The '100x' claim is obviously exaggerated. C# is certainly one of the most used programming languages there is. You can run also C# code very quickly, but have the option (but not the need) to AOT compile it. I would say the only real edge JS has is the ability to run natively in the browser. It was built for that purpose, and in my opinion, that is where it shoul…

> It also has TypeScript which pairs well with agentic coding loops The language syntax has nothing to do with it pairing well with agentic coding loops. Considering how close Typescript and C# are syntactically, and C#'s speed advantage over JS among many other things would make C# the main language for building Agents. It is not and that's because the early SDKs were JS and Python.

> C#'s speed advantage over JS among many other things would make C# the main language Nobody cares about this, JS is plenty fast for LLM needs. If maximum performance was necessary, you're better off using Go because of fast compiler and better performance.

>If maximum performance was necessary, you're better off using Go because of fast compiler and better performance.

That's not true, if anything, C# is faster and also compiles fast enough.

What do you mean by "context" here?

Claude Code moved to partial file reads over the summer.

Super premature optimization. It’ll hallucinate what lines it needs to read, it’ll continuously miss critical context in favor of trimming tokens.

Luckily we can now hook and force the agent to read full files at least once.

> Anthropic has direct incentive to keep Bun excellent. Huh, this feels very odd to read and buying a company outright is definitely not the only way to push Bun to be excellent. Contributing to Bun from their developers, becoming a sponsor, donating through other means, buying 'consulting services' or similar, or even forking it and keeping it up to date would all be also steps towards keeping the Bun excellent.

since Anthropic is one of the only companies using the Bun Runtime, not just the bundler like most do, they want to make sure the runtime stays the focus. This is good for both companies and us tbh since they wont switch focus to whats popular at the moment

It's fine but why is Js a good language for agents? I mean sure its faster than python but wouldn't something that compiles to native be much better?

JS has the fastest, most robust and widely deployed sandboxing engines (V8, followed closely by JavaScriptCore which is what Bun uses). It also has TypeScript which pairs well with agentic coding loops, and compiles to the aforementioned JavaScript which can run pretty much anywhere.

As 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…

Crash. According to my experience trying it many times oves the past years.

It feels like a very unfocused project, every few months they introduce a new feature that is to replace an entire class of tools, while the original promise of "drop in Node replacement" was never fulfilled (or at least, that was the vibe for the past years when I was still paying attention).

We'll see how this works out but speed + lack of scope never works out well in the long term.

The answer is typescript is a much simpler and more pleasant developer experience than any other language. These are products they need to, and often originate from, fast churn of code/features.

Otherwise they’d be building these types of things in Rust.
