CafeCar is a composable view extension for Rails: it renders complete index, show, new, and edit interfaces straight from your models, with no DSL and no boilerplate. Every index ships with keyword search, URL-based filtering and sorting, pagination, and one-click CSV export. Authorization runs on Pundit with attribute-level permissions; forms and Turbo Stream (Hotwire) responses render automatically. Every default can be overridden application-wide or per model with ordinary Rails. It makes admin panels, internal tools, and back-office apps on Rails 8 trivial.
