Entropic vs Verdaccio: What are the differences?

Entropic: A federated package registry for anything. It is a new package registry with a new CLI, designed to be easy to stand up inside your network. It features an entirely new file-centric API and a content-addressable storage system that attempts to minimize the amount of data you must retrieve over a network. This file-centric approach also applies to the publication API; Verdaccio: A lightweight private npm proxy registry. A simple, zero-config-required local private npm registry. Comes out of the box with its own tiny database, and the ability to proxy other registries (eg. npmjs.org), caching the downloaded modules along the way.

Entropic and Verdaccio can be categorized as "Front End Package Manager" tools.

Entropic and Verdaccio are both open source tools. It seems that Verdaccio with 7.19K GitHub stars and 656 forks on GitHub has more adoption than Entropic with 4.15K GitHub stars and 149 GitHub forks.
