Akelos is an MVC framework for PHP that tries to bring the magic of Ruby on Rails to the PHP world. Akelos based applications can run on most shared hosting service providers since Akelos only requires a standard PHP installation on the server. Akelos is designed to make developers lives simpler by solving complex problems with unusual speed and productivity. Favoring "convention over configuration" leads to the creation of uniform and simpler-to-understand code.
JInto is a plugin for Eclipse that lets the developer easily edit and maintain resource bundles (files that hold the localized strings for an application). It features parallel editing of all language versions (side by side), warnings when no text has been provided for a specific key, or when the text for one key is identical for different languages, and a search wizard to locate unused strings (strings that are referenced, but not actually defined in the resource bundle). It has been tested under Windows and Linux.
Java+ is a Java preprocessor that adds its features to any Java compiler. It has long, multi-line strings with executable inclusions like Perl or Ruby, optionally segregates Java+ strings into ResourceBundle files, eliminates the need for JSP or ASP and their implied need for Java compilers on deployment servers (a security concern), and adds absolutely no overhead in either space or time. There are graphical and command line interfaces, and a simple, general, and recursive string syntax.
LGI is a lightweight GUI library and application framework. It supports cross-platform widgets, threads, Unicode, a multi-language resource file in XML (with graphical editor), drag and drop, common dialogs, network support with implementations of common protocols, and an HTML control.
Poedit is a gettext translation (.po file) editor for Unix, Windows, and OS X. It aims to provide translators with a simple, easy to use user interface with all the essential tools such as spellchecker or translation memory. It can also be used to manage translations for small projects.
