ScriptBasic is an interpreter for the old language BASIC. It runs on Win32 as well as on UNIXes as a command-line or CGI program interpreter. It includes an interpreter, a compilable, well-documented embedding and extending interface for the C programmer, and a rich set of commands and functions.
Scsh is a systems-programming environment for POSIX systems and Win32, embedded in the Scheme programming language. It includes a high-level process notation for writing shell-script like programs, with pipelines and redirections. Scsh additionally provides low-level access to POSIX primitives, plus important non-POSIX extensions such as sockets. Scsh is implemented on top of Scheme48, a portable bytecode implementation of Scheme. A number of user-contributed extensions are available, including an extensible HTTP and FTP server, a socket-level PostgreSQL interface, a programmable text formatting language, and a Postscript generation language.
Kadet is a multi-threaded, multi-purpose server written in C. It is highly extensible, well written, and equipped with a great set of libraries including built-in scripting, a persistent database, object memory management, etc. It is very easy to develop. The server protocol is currently HTTP/1.1. SSL is supported via OpenSSL.
WebComp is a tool for using scripting to compose and configure Web sites from various existing components, such as static HTML, Java Servlets, Java server pages, and others. It includes a scripting language, a component model/framework, and a set of basic pluggable components to use with it. It is based on Java Servlets.
Factor is a dynamically-typed stack-based programming language. Factor runs on various OSes and CPU architectures, and provides an optimizing compiler, interactive development environment, powerful collections, higher order programming, continuations, and a growing library of contributed code.
Haserl is a small CGI program that parses POST and GET data from Web clients and provides a PHP-like syntax for writing dynamic Web content. A Unix shell is used for the scripting language. Lua is also supported as an embedded scripting language. It is intended for environments where something like PHP is too big, and compiles to around 20KB.
PTM is a Perl/HTML hybrid language, written entirely in Perl, and similar to PHP in tag syntax. It allows for the ease of PHP-style inline code in your dynamic HTML documents, while supplying the power of Perl that many find to be sorely lacking in PHP. PTM's parser application, referred to as the PPA, acts as an Apache plugin, a standalone parser placed in the cgi-bin, or a command line parser (for debugging purposes), and is distributed for both Unix and Window platforms. Additionally, PTM wraps many variables common to PHP to ease the transition between PTM and PHP when switching back and forth.
