BOTTENDER is an open-source JavaScript framework for cross-platform bots. It benefits from the latest improvements in JavaScript (e.g. async/await) and tries to offer a consistent development experience while developing bots on multiple messaging platforms.
By far the best Bot Framework. Especially the managment of session. I'm a deep learning engineer and find it really easy to implement a dialogue state prediction server to work with Bottender. Just <3
Pros:Flexible, easy to test, functional session management
Cons:nope
