Over the past year Oswald has grown tremendously and an incredible number of handy features, both big and small, have been implemented.
It's a really powerfull product to use, whether uou are building a POC of a full production ready chatbot. You'll see that the development time to go from an idea to a working protoype is measured in days when using Oswald, compared to weeks/months when using other cloud based chatbot platforms.
It's a bot framework with built-in python support to implement external integrations, what else could you want?
