Composercat

Composercat is a comprehensive GUI for the Composer package manager, designed both for professionals and people taking their first steps with Composer.

The app can manage all your Composer configurations, update packages and even take care of updating Composer itself. There's no need to edit the composer.json file manually.

Composercat integrates seamlessly with packagist.org, which means you will always have up-to-date information about your installed packages.
