The Yahoo! Application Platform allows you to reach our users and improve the Yahoo! user experience by building and deploying new applications directly onto Yahoo! pages, writing code the way you love to write it. We're looking to you to help us build the next big thing on Yahoo!, and in turn we'll shower you with traffic and users. Sounds like a win/win, doesn't it? That's our goal!
You don't have to be a huge software development house to get your Apps onto Yahoo!. Build powerful Apps using your software stack, your environment, and your servers. You can write your application in whatever language you want and proxy it back to us. Instant distribution.
You can easily make your applications socially relevant to users. You can let a user interact with their connections and connections' content by leveraging the Yahoo! Social Directory API.
Keep an eye on your applications on your My Apps page.
Questions and suggestions on the Application Platform are discussed on the Yahoo! Application Platform Developer Community forum. If you have questions or need technical support, please use this forum.
