Is there really that many? Outside of browsers, I know of Node, Deno and now Bun. Is there really that many serious attempts to replace node?

The engine (V8 analog) is not a "Zig engine", it's javascriptcore. The wrapper is Zig, like node is C/C++ and deno is Rust.

My bad, their page says

"Bun uses the JavaScriptCore engine, which tends to start and perform a little faster than more traditional choices like V8. Bun is written in Zig, a low-level programming language with manual memory management."

I conflated these two.

Bun is using the JavaScriptCore engine which is the Webkit/Safari Javascript engine. It is not written in Zig.
