Recently there are a lot of tools to test the receiving part of your webhooks. I’m personally using http://www.postbin.org/ for my tests. I couldn’t find however a good way to “feed” my webhooks with a constant stream of fresh entries. There is a Superfeedr Simpulator, but it’s to much bound to their service. I needed a more general solution, so I created AtomGen - Infinite Atom Entries Generator.
