libnet.so provides the Berkeley sockets on R5, later replaced by the more common libsocket/ libbind.so nomenclature and libnetapi on R5, later replaced by libbnetapi provides the modified version of Nettle. The Network kit provides either a rudimentary ( BeOS R5 and lower) or almost complete ( BeOS Dano and higher) implementation of Berkeley sockets and BIND as well as "native" functions based on the Nettle C++ networking library.

The Support kit provides more advanced functions which do not readily fall into another kit, such as assisted memory allocation and list support. The Kernel kit provides threading, semaphores and the ability to access system information, and is also in libbe.so. In the Haiku version of the API, it adds the Layout API, that provides tools to design user interfaces. The majority of libbe.so comprises this kit. The Interface kit provides a large collection of widgets for building graphical applications from the main window class down to dialogue boxes, including font handling, drawing operations and rendering control.

Storage kit classes are mostly in libtracker.so, Tracker being the native file manager on the OS. The Storage kit provides methods related to access to the file system, including manipulating files, navigating the file system hierarchy, creating and managing symlinks, dealing with file open/save panels for graphical applications, as well as dealing with Be File System attributes. The Application kit contains the basic classes required to launch a BeOS application, as well as support for the global clipboard, inter-application and internal messaging, timers, rosters and other functions seen as required to support any graphical application.Application kit classes are supported by libbe.so.
