LazyJ is a rapid development framework for Java-based Web applications. It provides tools to (partially) replace and complement the standard servlet API, a fast templating engine, database connection pool, database-backed sessions, content and data caching, and time-bounded execution. Its sole purpose in life is to make the programmer happy.
Gravacacher is very simple and lightweight caching server designed for one specific purpose: to cache avatar images from services like www.gravatar.com, which provide "globally recognized avatars". Typically, Gravacacher will be deployed on sites that host blogs or forums which depend on gravatars. Gravacacher supports a security mechanism that allows it to answer only queries made via URLs generated by your server software, such as blog or forum engines, permanent cached entities, and both positive and negative TTLs when caching.
Pixane is an image processing library for Tcl that allows the scripting of all kind of image transformations. It supports reading from and writing to a large set of file formats (JPEG, PNG, GIF, BMP, WBMP, etc) and provides anti-aliased text rendering and a set of built-in fonts. It doesn't requires Tk, so it can be used to easily generate images dynamically from CGI. Binaries are provided for many platforms as dynamic libraries with no external dependencies for easy deployment. It is also a core component of the eTcl distribution.
The Mobile Web Proxy is a (CGI) tool to make more Web pages available from some mobile devices (cell phone Web browsers, etc.). It employs tag cleaning and paging so that Web pages it can access have far greater chances of being rendered on devices that cannot display overly large or complex pages. It is simple, but it seems to substantially extend the portion of the Web available from devices that otherwise display messages like "413: Page cannot be displayed."

Bare XML is a "bare" XML parser with all primary parsing done via a simple state engine with about 20 or so different states. A tree structure is created during parsing, with all node names and values linked via pointers directly into the original text buffer. As such, Bare XML is extremely fast and simple. Currently, the parser is available in a perl module with Perl glue to turn the created tree into a Perl hash tree. The module name is XML::Bare.
Puno is a PHP module (PHP5 and Linux/Unix only) that brings the OpenOffice.org UNO Programming API to the PHP userspace.
