Ruby web framework and Rails alternative. Occupies roughly 5% of the Ruby web-framework market alongside Roda, Sinatra, and Bridgetown (Rails holds ~95%). Philosophically modular — you can disable the router, controllers, validations, persistence, or views entirely and only install what you use, similar to Roda's plugin system. With Hanami 2.1, the view layer is officially done and extracted into a framework-agnostic Hanami View gem usable in any Ruby app. Does not ship its own real-time/cable solution; combined with LiteCable + AnyCable in an Internet-of-Things example to provide real-time support.
