+- [rollup](https://rollupjs.org/) for production
+  - Better plugin api / ecosystem than esbuild
+
+The fact that there are two different bundlers isn't optimal, this is where comes:
+
+## Rolldown
+
+> [Rolldown](https://rolldown.rs/) is a JavaScript bundler written in Rust intended to serve as the future bundler used in Vite. It provides Rollup-compatible APIs and plugin interface, but will be more similar to esbuild in scope.
+
+## Oxc
+
+[Oxc](https://oxc.rs/) (The JavaScript Oxidation Compiler) is a collection of high-performance tools for the JavaScript language written in Rust.
+
+The goal of the project is to provide the next generation toolchain for JavaScript low-level abstraction that each can share so that:
