TestNetwork is a commercial version of TestMaker that provides a distributed test environment for scalability and performance tests and service monitoring. TestNetwork runs TestMaker intelligent test agents on multiple machines to achieve virtual user levels not possible with TestMaker. It makes it easy to configure a rack of servers to create 10,000 to 100,000 virutal users. It also makes it easy to set up a group of servers distributed around your network to show how your Web-enabled application, including Web Service, is performing.
Firebolt is a network protocol oriented library. It's not another socket library; it offers higher level services to the developer. You can structure your protocol in the form of states and the transitions between those states with the use of your custom events. Thus you no longer need to worry about what data you just received from a socket and whether or not those data are expected in the current state of your network code, since that sort of validation is all performed by Firebolt.
DevelKit Framework is an GNUstep/Cocoa framework with tools for reading, understanding, and generating source code from other applications. Its goal is to allow applications to generate code from non-textual representation, such as diagrams or other kinds of descriptions. Example features: an ObjectiveC source reader and generator, a project builder class, source structure related classes (class, method, and instance variables), templates, a tool for automatically generating accessor (getter ad setter), dealloc and archiving methods (interface and implementation) for a given class, and more.
