Modern Ruby web framework built on clean architecture principles — an alternative to Rails for teams that want explicit dependencies, interactors, repositories, and strict separation of concerns. Hanami 2.0 (2022) was a near-complete rewrite: dry-rb ecosystem integration (dry-container, dry-auto_inject), ROM (Ruby Object Mapper) for data persistence instead of ActiveRecord, functional core/imperative shell patterns. No magic, no monkey patching — Hanami apps are plain Ruby objects with explicit wiring. Better testability, smaller memory footprint, faster boot times than Rails.
