rails_visualizer introspects a Rails application and generates a self-contained interactive HTML dashboard with no server, no config, and no Node.js required for end users. Run one Rake task to explore models, associations, routes, controllers, jobs, mailers, migrations, and gems through a polished 8-tab UI with search, filters, an ER diagram canvas, and built-in health checks.
