LetsBeef.com is a website where rap artists can compete online in rap battles, through the use of Macromedia Flash technology. Users can directly record their voice directly over instrumental music by hooking up a microphone to their computer. Recordings are posted on the website as battles and other participants around the world can join in. Winners are determined by the members of the site, who have to vote on battles to gain credits to continue battling. There are customizable virtual emcee characters, monthly and all time rankings, tournaments, crews, crew battles, cyphers, hoods and more which will be described below in detail.

The website is built on popular web tools, applications and languages: Symfony PHP Framework, MySQL Database, Apache Web Server, PHP/HTML/dHTML/JavaScript/AJAX Languages, Adobe Flash, Adobe Flash Media Server and vBulletin forum software. The entire site is basically build around vBulletin's user and usergroup system, and the Symfony PHP Framework. We use the vBulletin user database as our sign on for the entire site, so users only need to log in once to battle and use the forums. We use the usergroup system to determine regular users, exclusive users, staff and crews. We have separate tables for all other areas we built around the forum, such as the battle system, ranking system, cypher system etc. We built our recording application in Flash and interfaced it with Flash Media Server to do recording and streaming.
