Packagist is a very nice tool to upload your open-source projects so others can install, use, and upgrade them easily from the terminal. It has an incredible big amount of packages for you to install. Review collected by and hosted on G2.com.

I have nothing to say against Packagist. It is beneficial when you want to install many open-source packages in your PHP projects. You don't have to configure too much; just run composer install, and that's it. Review collected by and hosted on G2.com.
