Just vs Webpacker: What are the differences?

Just: A library that organizes build tasks for your JS projects. It is a build task definition library. It stands on the shoulders of two excellent and well tested libraries: undertaker and yargs. It also provides what we call "stacks" to complete the workflow of building a repository; Webpacker: Use Webpack to manage app-like JavaScript modules in Rails (by Rails). Webpacker makes it easy to use the JavaScript preprocessor and bundler Webpack to manage application-like JavaScript in Rails. It coexists with the asset pipeline, as the purpose is only to use Webpack for app-like JavaScript, not images, css, or even JavaScript Sprinkles (that all continues to live in app/assets).

Just and Webpacker can be primarily classified as "JS Build Tools / JS Task Runners" tools.

Just and Webpacker are both open source tools. It seems that Webpacker with 4.34K GitHub stars and 927 forks on GitHub has more adoption than Just with 1.31K GitHub stars and 44 GitHub forks.

What are some alternatives to Just and Webpacker?
Webpack
A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows to load parts for the application on demand. Through "loaders" modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.
gulp
Build system automating tasks: minification and copying of all JavaScript files, static images. More capable of watching files to automatically rerun the task when a file changes.
Grunt
The less work you have to do when performing repetitive tasks like minification, compilation, unit testing, linting, etc, the easier your job becomes. After you've configured it, a task runner can do most of that mundane work for you—and your team—with basically zero effort.
rollup
It is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the new standardized format for code modules included in the ES6 revision of JavaScript, instead of previous idiosyncratic solutions such as CommonJS and AMD.
Vite
It is an opinionated web dev build tool that serves your code via native ES Module imports during dev and bundles it with Rollup for production.
