Bower vs Verdaccio: What are the differences?

Developers describe Bower as "A package manager for the web". Bower is a package manager for the web. It offers a generic, unopinionated solution to the problem of front-end package management, while exposing the package dependency model via an API that can be consumed by a more opinionated build stack. There are no system wide dependencies, no dependencies are shared between different apps, and the dependency tree is flat. On the other hand, Verdaccio is detailed as "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.

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

Some of the features offered by Bower are:

• Bower operates at a lower level than previous attempts at client-side package management – such as Jam, Volo, or Ender. These managers could consume Bower as a dependency.
• Bower's aim is simply to install packages, resolve dependencies from a bower.json, check versions, and then provide an API which reports on these things. Nothing more. This is a major diversion from past attempts at browser package management.
• Bower offers a generic, unopinionated solution to the problem of package management, while exposing an API that can be consumed by a more opinionated build stack.

On the other hand, Verdaccio provides the following key features:

• Simple Configuration
• Uplinks
• Package Access

Bower and Verdaccio are both open source tools. Bower with 15.2K GitHub stars and 1.97K forks on GitHub appears to be more popular than Verdaccio with 7.19K GitHub stars and 656 GitHub forks.
