CrossSync is a Web-based client/server configuration management platform. It provides a simple, easy to use, but powerful API platform for managing any number of heterogeneous Unix systems. Administrators can track configuration changes made anywhere across their network, simultaneously roll out new configurations to multiple servers, and restart services on many servers at once, even if they are running different operating systems. A light-weight agent application runs on each of the organization's servers to securely communicate with the CrossSync platform.
