GenScriber is a transcription editor for census records, church records, birth, marriage ,baptisms, burials, index records, etc. Data can be entered in a spreadsheet grid, or a word processor text editor. Both types of input provide stable, non-volatile editors, designed for genealogical data input. All cell inputs are alphanumeric. No assumptions are made about the data type. Dates and values remain exactly as you entered them. The worksheet and text pad work independently. They can be used to edit different data by switching between the tabs. It is of course possibly to copy/paste data between the editors.
GWintree is a GEDCOM-based genealogy program. It provides facilities to record, view, edit, and merge genealogy data, and to produce genealogy charts, family trees, and reports in a range of formats, including HTML. Charts can show all relatives, ancestors only, or descendants only. HTML charts allow you to click on a person in your HTML report to see where they are on the chart. Automatic matching and merging of genealogy data between files is supported.

It is possible to show a tree of ancestors and descendants for any person, showing any number of generations. Other facilities are provided for showing email directories, birthday reminders, facehall, and more. It has a simple configuration, makes heavy use of CGI (and other CPAN modules), generates valid XHTML, and has support for Unicode and multiple languages.
GenealogyJ is a full-featured standalone Java application that can handle all of your genealogic information. It provides different graphical components for working on your family tree and is GEDCOM compliant. It requires a Java 1.4 Virtual Machine and runs on Windows / Mac / Linux.
