Git

Git is a version-control system for tracking changes in computer files and coordinating work on those files among multiple people. Simply put, Git is the single tool virtually all modern developers rely upon to manage development, code review, testing and deployment.

As a distributed revision-control system, Git is aimed at speed, data integrity, and support for distributed, non-linear workflows. As with most other distributed version-control systems, and unlike most client–server systems, every Git directory on every computer is a full-fledged repository with complete history and full version-tracking abilities, independent of network access or a central server.

Note: FileMaker is a very rare exception to this. The platform is unable to take part in Git tools and workflows due to its encapsulation of code and core assets within a "block box" binary file format that’s incompatible with source control.
