Bun isn't a node.js wrapper. It's an alternative to node.js that sits at roughly the same spot in the stack.

Node.js is a distribution of the V8 JavaScript engine (the thing that executes JavaScript in the Chrome browser), along with a bunch of standard library code written mostly in C++.

Bun is a distribution of the JavaScriptCore engine (the thing that executes JavaScript in the Safari browser), along with a bunch of standard library code written mostly in Zig (and now Rust). Bun's standard library is in many cases compatible with or inspired by the Node.js standard library, but with some changes for convenience and performance.

Answering “who is even using this software” is unfortunately missing in your answer. I am honestly curious. I’ve never seen it “in the wild” (in job descriptions, hearing from past colleagues, meetups etc). Only place I heard about it is HN and Twitter.

    It's primarily used by people who tend to sit on the cutting edge e.g. startups and developers who follow the latest tools. It's not well worn enough to be adopted by slower enterprise environments. Bun is well known within web development but if you don't work in the space and don't keep up to date with modern tooling it's unlikely you would have awareness of it.

    To my limited knowledge, "serious" production systems most likely use Node.js instead of any alternatives, and I don't see any movement towards adopting Bun.
