Laravel Brain: Visualize Your Application's Request Lifecycle

Laravel Brain is a package that scans your Laravel application and renders an interactive graph of how requests flow through it. Install it, run the scan, and you'll get a visual map of your routes, controllers, services, repositories, models, jobs, events, Artisan commands, scheduled tasks, and broadcast channels all in one place..

Interactive Graph

Each route, controller action, service, model, job, and event appears as a colored node with arrows showing how data moves between them. You can click any node to inspect its details, view the source code inline, or pull up a flowchart of the method's internal logic.

Routes are organized into their own tabs so you can focus on a single endpoint without wading through the whole application at once. You can export graphs as PNG or Mermaid diagrams and choose from several layout hierarchical dagre, force-directed, breadth-first, circle, or grid. Dark and light themes are included, and the viewer will flag "fat classes" (controllers or services with more than 300 lines or 10 methods) as a quick sanity check on code health.
