Pivot is a tool to create weblogs and other dynamic websites, started by Bob den Otter, a developer from the Netherlands. The first release appeared in June 2001.

Pivot is written in PHP and requires no additional libraries to run, nor any databases like MySQL. “Some of the features of Pivot are:

* Sophisticated Categories/Weblogs system, so you can maintain several weblogs and publish your entries how you like;
* Template based. Fully adaptable to your wishes;
* Keeps simple statistics of how your visitors came to your site;
* Easy to upload and include pictures with your log-entries;
* Allows for making thumbnails of uploaded images;
* Comment system that remembers your visitors (if they wish);
* Creates RSS and Atom feeds;
* IP-blocking, to prevent certain people from leaving comments;
* Archiving by week or month, and/or by category;
* Optionally supports full wysiwyg editing of your posts;
* Supports Textile, both in entries and in comments;
* No external databases are required, just plain PHP;
* Makes valid xhtml, when possible.”
