-Gitploy is a tooling that helps your organization build the deployment system in minutes. It enables your organization **to deploy in the same manner** without worrying about  the implementation details of delivering different types of applications (e.g., web, native). and **to deploy differently** for each application by a simple configuration file, respectively.
