Bun Ported to Rust in 6 Days: Speed or Madness?

Ever woken up with the thought, "Why not port a popular JavaScript runtime to Rust in a week"? No? Well, one brave soul did. Bun, originally written in Zig, now has a Rust version — and it took just 6 days.

Yes, you heard that right. Bun on Rust is like swapping your car's engine while it's still running. The developer ported key components, including the HTTP server and parser, to Rust. It's unstable, but the sheer audacity is impressive.

Of course, this isn't the first time Rust has been bolted onto something that already works. But there's a healthy dose of madness here: the original Bun hasn't even left beta, and we already have a fork in another language. It's like being offered a second coffee before you've finished the first — nice, but why?

For developers tired of nightly deploys and broken CI, this news might be another headache. On the flip side, it's a great example of how Rust continues to take over the world — even if it means rewriting things that aren't even finished yet.

METABYTE studio comment: We don't rewrite projects in 6 days (we finish our coffee first), but if you need a reliable and fast system in Rust — give us a shout. Bun on Rust might be half-baked, but our solutions are fully cooked.
