PunBB is a fast and lightweight PHP-powered discussion board. It is released under the GNU General Public License. Its primary goals are to be faster, smaller and less graphically intensive as compared to other discussion boards. PunBB has fewer features than similar software, but is generally faster and outputs smaller, semantically correct XHTML and CSS compliant pages.

Currently, PunBB runs on a number of operating systems that are able to support the PHP scripting language. To store its data, PunBB relies on either MySQL, PostgreSQL or SQLite.
