GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
queXC is a Web-based data cleaning and coding/classification system that takes a data file (such as data collected from a questionnaire) and cleans the text input fields by spacing them and spell checking them. It allows operators to code text fields to existing coding schemes, or to create a coding scheme on the fly. Multiple operators can code and clean simultaneously, with the ability to assign operators to do particular codes. The queXC system includes some coding schemes created from ABS (Australian Bureau of Statistics) data. It can be used as an open source replacement for Nvivo in some situations.
MIB Smithy is an application for SNMP and COPS developers, MIB and PIB designers, and Internet-draft authors. It provides a GUI-based environment for designing, editing, and compiling MIB and PIB modules according to the SMIv1, SMIv2, and COPS-PR-SPPI standards. It accelerates the development process by providing an easy-to-use GUI-based environment for developing the specifications without the syntax and formatting concerns of editing the modules by hand. It includes a number of built-in basic SNMP management tools, XML support, and (with MIB Smithy Professional) support for custom compiler output formats.

It uses much of the Mozilla source code powering such successful siblings as Firefox, Thunderbird, Camino, Sunbird, and Miro.
