cgi-util is a fast, easy to use C library for creating CGI programs. Functions are available for initialization (parsing), grabbing fields (by string, integer, double or boolean value), embedding HTML files, and more. It accepts both POST and GET request methods and has extensive error handling.
CGI::Application is a Perl framework intended to make it easier to create sophisticated, reusable Web-based applications. This module implements a methodology which can make Web software easier to design, easier to document, easier to write, and easier to evolve. CGI::Application builds on standard, non-proprietary technologies and techniques, such as the Common Gateway Interface and Lincoln D. Stein's excellent CGI.pm module. CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system, or Web server.
CGILua is a tool for developing dynamic HTML pages and manipulating input data from forms. It uses the interpreted language Lua for codifying its scripts. It has been on the road for almost 8 years now, being used in many Web products and sites. It is extensible through Lua libraries and dynamic loading of C/C++ libraries. Scripts can be written as Lua programs or HTML templates (HTML with Lua code embedded). Scripts are platform-independent.
CGIWrap is a setuid wrapper that allows users to install and execute their own cgi scripts that get executed as their own userid. Much of the idea of suexec came from CGIWrap, however, cgiwrap stands on its own, and works with all web servers. CGIWrap must be installed by a system administrator, but after that, users can do their own web scripting.
cgi_buffer is a group of libraries that may be used to improve performance of CGI scripts (and other content generation engines) in some circumstances by applying performance-enhancing HTTP mechanisms that are typically not supported by them. Currently, Perl, Python, and PHP4 are supported. The Python library may also be used as a wrapper around another CGI script.
CGI_UTILS is a set of three C++ classes: CGI, Template, and Session. CGI wraps the CGI protocol. Template provides an easy way to use templates in your CGI applications. It knows about variables and datasets (tables). Session provides the ability to pass data between your programs through shared memory.
