Stealth is an open source Ruby framework for conversational voice and text chatbots.

Stealth is inspired by the Model-View-Controller (MVC) pattern. However, instead of calling them Views Stealth refers to them as Replies to better match the chatbot domain.

• The Model layer represents your data model (such as Account, User, Quote, etc.) and encapsulates the business logic that is specific to your bot. By default, Stealth uses ActiveRecord.
• The Controller layer is responsible for handling incoming requests from messaging platforms and providing and transmitting the response (reply).
• The Reply layer is composed of "templates" that are responsible for constructing the respective response.

In addition to being inspired by Model-View-Controller (MVC) pattern, Stealth as a few other awesome things built in for you.

• Plug and play services. Every service integration in Stealth is a Ruby gem. One bot can support multiple chat services (i.e. Facebook Messenger, SMS, Alexa, and more) and multiple NLP/NLU services.
• Advanced tooling. From web servers to continuous integration testing, Stealth is built to take advantage of all the great work done by the web development community.
• Hosting you know. Stealth is a Rack application. That means your bots can be deployed using familiar services like Docker and Heroku.
• Ready for production. Stealth already powers bots for large, well-known brands including: Humana, TradeStation, Haven Life, and BarkBox.
