Plesk Obsidian Composer
Plesk Obsidian is our most powerful management platform yet. From Onyx to Obsidian, Plesk has evolved, helping you reach your business goals faster. Full details here http://ple.sk/Obsidian
Plesk Obsidian comes with Composer out of the box - a tool for dependency management in PHP, which allows installation and update of a pre-declared set of libraries a project depends on. The most important Composer operations are available in the Plesk UI and users do not need to use SSH to install applications, review dependencies or update them to the latest versions.
