Barracuda's CSP language (similar to Active Server Pages) makes it easy to generate traditional server web-applications. With CSP, developers can embed C or C++ programs directly into an HTML template page created by an HTML designer. The rich C and C++ API, modelled after enterprise server APIs, provides methods that make it easy to design applications based on the common Model-View-Controller paradigm. The object oriented virtual file system makes it possible to delegate user requests, such as HTTP GET and HTTP POST, to any resource or resource collection.

Barracuda comes with a number of ready to use resource collections, including the ability for clients to read and write files to any directory in an embedded file system, and read files directly from within ZIP files. Resources can be dynamically installed and removed during runtime. Thus, a ZIP file can be uploaded using HTTP(S) and dynamically installed on the virtual file system.

Barracuda provides a number of advanced plug-ins, including web services, such as SOAP, UPnP, WebDAV, and a web interface to any SNMP MIB. Barracuda's host tools include a graphical MIB editor and compiler, Interface Definition Language (IDL) compiler for the EventHandler, and a compiler/linker for the CSP scripting language. Barracuda also provides a host simulation environment that enables designers to develop, run and test their code on any UNIX or Windows machine without requiring target hardware.
