SocketWrench is part of a package developed by Catalyst called SocketTools. In addition to the comprehensive, but fairly low-level, access that SocketWrench provides, SocketTools includes components and libraries for many of the popular Internet application protocols. There are three editions of SocketTools available, and all three include both 16- and 32-bit components, royalty-free redistribution licensing and a thirty day money-back guarantee.

The SocketTools Visual Edition consists of 16-bit Visual Basic (VBX) controls and both 16-bit and 32-bit ActiveX (OCX) controls for use with visual development environments such as Visual Basic, Visual C++ and Delphi. A total of nineteen controls provide client interfaces for the major application protocols such as the File Transfer Protocol, Simple Mail Transfer Protocol, Domain Name Service and Telnet. All versions of Visual Basic from 2.0 and later are supported, and the ActiveX controls can be used with any 32-bit development tool that supports COM and the ActiveX control specification. The network controls support both synchronous (blocking) and asynchronous modes of operation and include trace debugging facilities. All of the controls are thread-safe and can be used in multithreaded containers, such as Internet Explorer.

The SocketTools Library Edition consists of 16-bit and 32-bit dynamic link libraries (DLLs), and can be used by virtually any Windows programming language or scripting tool. A total of sixteen libraries provide client interfaces for application protocols such as the File Transfer Protocol, Simple Mail Transfer Protocol and Telnet protocol. The application program interface for the Library Edition is implemented with a simple elegance that makes it easy to use with any language, not just C or C++. All of the libraries are thread-safe and can be used in multithreaded applications.

The SocketTools Enterprise Edition offers the best of both worlds for the corporate developer who needs visual controls for rapid application development, as well as the power and flexibility of dynamic-link libraries for developing core application systems. Including 16-bit Visual Basic controls, 16/32-bit ActiveX controls and 16/32-bit dynamic link libraries (DLLs), the Enterprise Edition is suitable for use with virtually any Windows development environment.
