I don't get it. Why would Anthropic need to own a JS runtime?

Because they have a product that makes $1bn+ a year that depends on having a good, stable, cross-platform JS runtime.

I'm still confused. Why not just pour a ton of resources into it since it's open source. I guess dev mindshare? It is a great product

Pouring a ton of resources into an open source project that raised $26m in VC doesn't guarantee that the project will stick around. Acquiring it does.

Buying Bun to ensure it sticks around doesn't pass the smell test unless they had very few months of runway left

Bun had four years of runway left.

You're describing Node.js which has existed for the last 15 years

And is owned by Microsoft. The theory is that by symmetry Anthropic should own a node competitor.

Microsoft doesn't own node.

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?

Because now the Bun team don't have to redirect their resources to implementing a sustainable business model.

No they don't.

Ok but node is even more stable and mature - compare node api parity in bun and also issue of bun vs node

But they are not using node any more?

That doesn’t require or benefit from acquiring Bun. Node continues to exist and serve fine.

I'm wondering if Bun would be a good embedded runtime for Claude to think in. If it does sandboxing, or if they can add sandboxing, then they can standardize on a language and runtime for Claude Code and Claude Desktop and bake it into training like they do with other agentic things like tool calls. It'd be too risky to do unless they owned the runtime.

Why would Sun then Oracle own Java? Why would Microsoft own .net? Why would Apple own swift?

IOW look where the puck is going.
