An open-source software tool, Huginn, operates like Yahoo Pipes and offers the additional security of running on a user's server, Klint Finley writes. How Huginn differs from other Web services is that it allows developers to create custom agents and manage their own data, he notes. As Huginn creator Andrew Cantino says, "[Yahoo] Pipes isn't really being maintained. If This Then That seems to be doing well, but I don't really know if it's going to stick around. Ultimately, I don't control the data."
