Note that "sandboxing" in this case is strictly runtime sandboxing - it's basically like having a separate process per event loop (as if you ran separate Node processes). It does not sandbox the machine context in which it runs (i.e. it's not VM-level containment).

When you say runtime sandboxing, are you referring to JavaScript agents? I haven't worked all that much with JavaScript execution environments outside of the browser so I'm not sure about what sandboxing mechanics are available.

https://nodejs.org/api/vm.html

Bun claims this feature is for running untrusted code (https://bun.com/reference/node/vm), while Node says "The node:vm module is not a security mechanism. Do not use it to run untrusted code." I'm not sure whom to believe.

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…

back in my day we used to write code on punch cards.

But how is another company that is also VC backed and losing money providing stability for Bun? How long before we hear about “Our Amazing Journey”? On the other hand, I would rather see someone like Bun have a successful exit where the founders seem to have started out with a passion project, got funding, built something out they were excited about and then exit than yet another AI company by non technical founders…

Anthropic may be losing money, but a company with $7bn revenue run rate ( https://www.anthropic.com/news/statement-dario-amodei-americ... ) is a whole lot healthier than a company with a revenue of 0.

I am fairly skeptical about many AI companies, but as someone else pointed out, Anthropic has 10x'ed their revenue for the past 3 years. 100m->1b->10b. While past performance no predictor of future results, their product is solid and to me looks like they have found PMF.

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…

> Culturally I see pure vibe coders as intersecting more with entrepreneurfluencer types who are non-technical but trying to extend their capabilities. Most technical folks I know are fairly disillusioned with pure vibe coding, but that's my corner of the world, YMMV

Anyone who has spent time working with LLMs knows that the LinkedIn-style vibecoding where someone writes prompts and hits enter until they ship an app doesn't work.

I've had some fun trying to coax different LLMs into writing usable small throwaway apps. It's hilarious in a way to the contrast between what an experienced developer sees coming out of LLMs and what the LinkedIn and Twitter influencers are saying. If you know what you're doing and you have enough patience you really can get an LLM to do a lot of the things you want, but it can require a lot of handholding, rejecting bad ideas, and reviewing.

In my experience, the people pushing "vibecoding" content are influencers trying to ride the trend. They use the trend to gain more followers, sell courses, get the attention of a class of investors desperate to deploy cash, and other groups who want to believe vibecoding is magic.

I also consider them a vocal minority, because I don't think they represent the majority of LLM users.

If I had the cash, I could sell dollar bills for 50 cents and do a $7b run rate :)

you have anthropic confused with something like lovable. anthropic's unit margins are fine, many lovable-like businesses are not.

Or I'm just saying revenue numbers alone don't prove anything useful when you have deep pockets.

My first thought went to how openai used Rust to build their CLI tool and Anthropic's CEO bought influence over Zig as a reaction.

> bought influence over Zig as a reaction

Elaborate? I believe Zig's donors don't get any influence and decision making power.

> 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.

> Nobody cares about this

And that was my point. The choice of using JS/TS for LLM stuff was made for us based on initial wave of SDK availabilities. Nothing to do with language merits.

The reference docs are auto generated from node’s TypeScript types. node:vm is better than using the same global object to run untrusted code, but it’s not really a sandbox
