GPP is a general-purpose preprocessor with customizable syntax, suitable for a wide range of preprocessing tasks. Its independence from any programming language makes it much more versatile than cpp, while its syntax is lighter and more flexible than that of m4. The syntax is fully customizable, which makes it possible to process text files, HTML, or source code equally efficiently in a variety of languages.

ht://Check is a link checker derived from ht://Dig. It can retrieve information through HTTP/1.1 and store it in a MySQL database so that after a "crawl", ht://Check can return broken links, anchors not found, content-types, and HTTP status codes summaries. ht://Check also performs accessibility checks in accordance with the principles of the University of Toronto's Open Accessibility Checks (OAC) project, allowing users to discover site-wide barriers like images without proper alternatives, missing titles, etc. A PHP interface lets the user query and view the results directly via the Web.
Performance Co-Pilot (PCP) is a framework and set of services for supporting system-level performance monitoring and performance management. It provides a unifying abstraction for all of the interesting performance data in a system, and allows client applications to easily retrieve and process any subset of that data using a single API. A client-server architecture allows multiple clients to monitor the same host, and a single client to monitor multiple hosts. Archive logging and replay are integrated so that a client application can use the same API to process real-time data from a host or historical data from an archive.
The CODE:NEO Application Server is a Web server extension that bridges the gap between web interfaces and compiled code. It allows the user to build "Joints" with .CnBin extensions, which can be called through the Web server and operate at ultra-fast speeds. CODE:NEO also comes with two API libraries (CnUtil and CnServer) that provide many convenient rapid development tools.
