MashUps are an exciting genre of interactive Web applications that draw upon content retrieved from external data sources to create entirely new and innovative services. They are a hallmark of the second generation of Web applications informally known as Web 2.0.

A MashUp is a website or Web 2.0 application that uses content from more than one source to create a completely new service. Much the way blogs revolutionised online publishing, mashups are revolutionizing web development by allowing anyone to combine existing data from sources like Amazon.com, eBay, Google, Strikeiron, Windows Live and Yahoo! in innovative ways.

Examples of MashUps built using AlchemyPoint include:
