Stealth is a Ruby framework for creating text and voice chatbots. It's design is inspired by Ruby on Rails's philosophy of convention over configuration. It has an MVC architecture with the slight caveat that views are aptly named replies.

Features

Deploy anywhere, it's just a Rack app
Variants allow you to use a single codebase on multiple messaging platforms
Structured, universal reply format
Sessions utilize a state-machine concept and are Redis backed
Highly scalable. Incoming webhooks are processed via a Sidekiq queue
Built-in best practices: catch-alls (error handling), hello flows, goodbye flows

Getting Started

Getting started with Stealth is simple:

> gem install stealth
> stealth new <bot>

Service Integrations

Stealth is extensible. All service integrations are split out into separate Ruby Gems. Things like analytics and natural language processing (NLP) can be added in as gems as well.

Currently, there are gems for:

Messaging

Voice

Alexa Skill (Early alpha)

Natural Language Processing

Analytics

Mixpanel

Docs

Versioning

Stealth is versioned using Semantic Versioning, but it's more like the Linux Kernel. Major version releases are just as arbitrary as minor version releases. We strive to never break anything with any version change. Patches are still issues as the "third dot" in the version string.
