DAISY Pipeline 2 is an umbrella term for various things.
DAISY Pipeline 2 is a desktop application.
DAISY Pipeline 2 can also be run as a service to which client programs can connect, through a web API.
The DAISY Pipeline 2 web application is an example of such a server-client configuration. Unlike with the desktop application, multiple users can work together in the same application, each through their own web browser, while the real work happens on a central server. The web application offers some additional features that are not available in the desktop application yet, such as “templates”.
There is also a command line tool.
DAISY Pipeline 2, in all its forms, is supported on Windows, Mac OS, and Linux.
