WeBid is an open source web auction application. WeBid was initially released in 2008. WeBid is one of the best open-source solutions for getting an auction site up and running quickly and cheaply.

Some of the key features which make WeBid a great choice are:

• An easy to use administration panel
• An inbuilt payment system allowing users to easily pay fees and their purchased items with their favorite payment gateways (these include PayPal, Authorize.Net)
• Incredibly easy to customize.
