Site Index is a simple script which generates HTML pages showing a site index for all of your local domains. It uses the natural hierarchy of your filesystem, so if you've organized your pages well, the job is fully automated. It breaks the index into multiple pages to respect a links-per-page limit, and can do some sorting/management of the results according to domain/page "importance".
Sitegrab is a URL grabber that parses IRC logs for data and then inserts it into a database that can be searched through a web interface using a combination of announcer name, date, partial url, and type of url. Also supported is an administration mode whereby urls can be edited and deleted through the web interface.
SWISH++ is a Unix-based file indexing and searching engine (typically used to index and search files on web sites). It was based on SWISH-E although SWISH++ is a complete rewrite. SWISH++ is at least 10 times faster and can handle much larger numbers of files. Additionally, it has unique features such as selective non-indexing, on-the-fly filters, user-selectable stemming, and more.
TYPO3 CMS is a Web Content Management System which features automatic creation of navigational menus, headlines, and other dynamic graphical elements, automatic conversion and scaling of images, the ability to present different templates based on variables such as client browser or country code, support for multiple templates on a site, and a built-in password-protection option. Pages can be timed to be shown on a certain date, be hidden on a certain date or just temporarily hidden. TYPO3 supports search in SQL-databases and redesigning of a website at once is just a matter of creating a single new template.
