SCADAR.NET is a web application.
A web application is a client-server software application in which the client (or user interface) runs in a web browser. In simple terms, this means the SCADAR.NET application software is hosted elsewhere (on a remote server) and SCADAR.NET users access the software using a user interface that's hosted within a web browser.
SCADAR.NET features functions and application extensions (API's).
