Node.js is also more stable, and it has started supporting TypeScript out of the box. I don’t think Bun will have many advantages after Node 26.
Node only does type stripping though. If you want proper TS support you still need a compiler.

There are tons of advantages. For instance, Bun includes a lot of features that would need a third party dependency in Node: db driver, S3 client, watch mode, bundler, JSX support, etc.
Switching to Go or Rust would only make sense if performance were the main priority, which doesn’t seem to be the case. Their current setup lets them ship quickly. A rewrite in Go would likely slow that down.
Codex moved to Rust, and you can see the trade-off. Performance improved, but release velocity dropped. They’re also still catching up to Claude Code, so they don’t face the same pressure to ship as fast.
The bun people likely have some fucked up incestial business relationship with some >dev manager at Anthropic and the same pattern is repeating. Only this cycle it's going straight to acquisitions, which honestly seems like a worse strategy and Anthropic will def can the bun engineers in less than <3 years or whenever they face an actual budget crunch that they can't stave off with more gulf money.
"The key point here is our programmers are Googlers, they’re not researchers. They’re typically, fairly young, fresh out of school, probably learned Java, maybe learned C or C++, probably learned Python. They’re not capable of understanding a brilliant language but we want to use them to build good software. So, the language that we give them has to be easy for them to understand and easy to adopt. – Rob Pike"
"I want a serious Node.js alternative."
So you ignore the one developed by the same guy?
:(
So Bun is going to become a fully vibe-coded codebase, with important details lost in translation.
I’ve been a huge supporter of Bun, but now I’d be extremely reluctant to deploy it in production.
It’s also a bit disappointing to see Jared change his mind so quickly. He’s an incredible developer with deep knowledge of how to write clean, maintainable, efficient code. But now it feels like his talent is being sidelined, and Claude has been given full control over the codebase.
Claude Code itself seems to be built that way: they keep piling on new features every day, but it has become this big, bloated Frankenstein slug.
Bun used to be a small, elegant, clean codebase. Now I’m worried it may turn into an unreliable mess.
Never attribute to malice that which can be adequately explained by incompetence, etc.
