What each one is

The product in its own terms, so the numbers below have context.

Composer/Packagist

Composer is a PHP dependency management tool that uses a centralized package repository (Packagist.org) to discover and install project dependencies. It supports version control integration, security scanning, and both public and private package repositories.

Independently observed

Yarn

Yarn is a modern package manager for JavaScript projects that prioritizes deterministic installations and includes built-in support for monorepos. It provides a complete solution for managing both dependencies and project structure with a focus on reliability and security.
