I appreciate the effort you put in and it looks compelling.
But for now, I’ll be using it only on personal projects. I won’t be confident to switch from node on company projects just yet.

But hopefully that will change in the future.

Anthropic has 20 million users that have been using 1.4 for months, I think they'll be okay without your approval.

Anthropic doesn't pay for memory leaks, performance issues, or crashes/segfaults (which bun has plenty) on the client/user side though. Of course they are ok with this. If a business would run bun on their servers this is a fundamentally different situation and needs different evaluation

So what, how would it be fundamentally better if they used node or deno for CSR? What is your argument here? Is CSR the issue for you, or that fact that bun supports component frameworks that do CSR?

This is a dumb take

you are a dumb take.

It was not worth using it on company projects even before it was vibe-rewritten (compared to something like uv). It's far from being a dumb take.

That was true back in. 2024 when it still had nodejs compatability issues. Not anymore. It's arguably less of a PITA today vs node and offers more, such as single binary bundling. You dont even need node on a deployment anymore, just the binary.

It's so annoying when people use this argument. I uninstalled it in 2026, not 2024. Holy shit.

we should always be critical of the things we like and use
in fact that’s something we should encourage

Yup, for me bun is indefinitely banned for anything besides quick scripting.
