Protopack

Protopack is a bundler for rapid prototyping built on Rollup, Babel, and PostCSS. Currently in alpha (v0.0.1-alpha.8), it offers a simple config file and an Express middleware for development. As a work-in-progress, it supports inline styles/scripts and basic HTML output, but lacks hot-reloading, image support, and custom plugin configuration. It differentiates by focusing on prototypes rather than production builds, with a minimal setup.
