Grunt vs Webpacker: What are the differences?
What is Grunt? The JavaScript Task Runner. 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.
What is 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).
Grunt and Webpacker can be primarily classified as "JS Build Tools / JS Task Runners" tools.
Grunt and Webpacker are both open source tools. It seems that Grunt with 11.9K GitHub stars and 1.55K forks on GitHub has more adoption than Webpacker with 4.29K GitHub stars and 893 GitHub forks.

Grunt has a broader approval, being mentioned in 796 company stacks & 429 developers stacks; compared to Webpacker, which is listed in 7 company stacks and 5 developer stacks.
