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…

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?

TS is enormous, has endless training data, and can interact with virtually anything on the Internet these days. Also, strong typing is very very useful for AI coding context.

Anywhere where the correct Java version is installed correctly, important caveat

Java’s cardinal sin was not owning the OS like Microsoft’s C# to force end-users to update the framework. Oracle really didn’t understand what they were sitting on with their Ubuntu competitor Solaris.

This has no longer been the case for C# for 10 years since the release of .NET Core and (now) .NET. The runtime is no longer bundled with the OS.

This is only true for older .NET Framework applications.

It's widespread and good enough. The language just doesn't matter that much in most cases

This is one of those, "in theory, there's no difference between theory and practice. In practice, there is" issues. In their, quality software can be written in any programming language. In practice, folks who use Python or JavaScript as their application programming language start from a position of just not carrying very much about correctness or performance. Folks who use languages like Java or C#, do. And you can…

perhaps many of those 'Folks who use languages like Java or C#'

do so because a boss told them 'thats the way we deal with correctness and performance around here'

the fact that their boss made that one decision for them does not somehow transmit the values behind the one decision.

It doesn't make a lot of sense that they'll compare Microsoft 365 Copilot with Claude Code, though? Like it is a legit CLI tool but we should ignore it because it shares the name with something else?

The GitHub Copilot CLI tool is brand new, they only launched that in September: https://github.blog/changelog/2025-09-25-github-copilot-cli-... Prior to that GitHub Copilot was either the VS Code IDE integration or the various AI features that popped up around the GitHub.com site itself.

Yeah but my point was it's pretty clear which Copilot the article was talking about and pretending like it could be anything beacuse "everything's copilot" is a L take sorry.

What is the business model behind open source projects like bun? How can a company "aquire" it and why does it do that? In the article they write about the early days We raised a $7 million seed round Why do investors invest into people who build something that they give away for free?

Free now isn't free forever. If something has inherent value then folks will be willing to pay for it.

Well, if they suddenly changed the license, we'd get a new Redis --> Valkey situation. Or even more recently, look at minio no longer maintaining their core open source project!

Currently Claude etc. can interact with services (including AWS) via MCPs. What the user you're replying to is saying the Bun acquisition looks silly as a dev tool for Node. However if you look at their binding work for services like s3[0], the LLM will be able to interact directly with cloud services directly (lower latency, tighter integration, simplified deployment). 0: https://bun.com/docs/runtime/s3

That doesn't make sense either. Agents already have access to MCPs and Tools. Your example is solved by having an S3 wrapper as a set of tools.

Being able to remove a layer of abstraction to get the thing done is usually good right?

Genuine question: why js? Why not something like c#: native, fast, crossplatform, strongly-typed, great tooling, supports both scripting (ie single file-based) and compiled to a binary with no dependency whatsoever (nativeAOT), great errors and error stacks, list goes on. All great for AI to recover during its iterations of generating something useful. Genuinely perplexed.

I thought c# was a dead language at this point?

but they are a company that burns billions every year in losses and this seems like a pretty random acquisition. Bun is the product that depends on providing that good, stable, cross-platform JS runtime and they were already doing a good job. Why would Anthropic's acquisition of them make them better at what they were already doing?

>but they are a company that burns billions every year in losses No they don't.

> As discussed previously, OpenAI lost $5 billion and Anthropic $5.3 billion in 2024, with OpenAI expecting to lose upwards of $8 billion and Anthropic — somehow — only losing $3 billion in 2025. I have severe doubts that these numbers are realistic, with OpenAI burning at least $3 billion in cash on salaries this year alone, and Anthropic somehow burning two billion dollars less on revenue that has, if you believe its leaks, increased 500% since the beginning of the year.
