HTML-over-the-wire front-end stack composed of Turbo (Turbo Drive, Turbo Frames, Turbo Streams) and Stimulus.js. Not Rails-specific — can be plugged into any HTML framework (e.g. Turbo Laravel for Laravel). Enables server-side-rendered modern monolith applications: asynchronous partial page loads, modals, multi-step forms, infinite pagination and live updates without full page refreshes. In Yaroslav Shmarov's wroclove.rb 2022 talk, recommended for early-stage teams and B2B desktop experiences (Jira-like information management systems, Twitch, Amazon, Salesforce, Facebook-desktop); unsuited for canvas-heavy apps like Miro, Figma, Photoshop, or Notion-style editors. Still a natural complement to read models in DDD: broadcasting Active Record-backed changes via Turbo Streams.
