Rails Trace Viewer

Real-time visualization of the Rails request lifecycle. Trace controllers, models, SQL queries, and distributed Sidekiq jobs in an interactive call stack tree. Perfect for debugging and education.

Rails Trace Viewer provides a beautiful, interactive Call Stack Tree that visualizes how your Rails application processes requests. It traces the flow from the Controller through Models, Views, SQL Queries, and even across process boundaries into Sidekiq Background Jobs.

What you get

• 🔍 Real-time Visualization: Traces appear instantly via WebSockets.
• 🧩 Distributed Tracing: Seamlessly links Controller actions to Sidekiq Jobs (enqueue & perform).
• 📊 Deep Inspection: Click any node to see arguments, SQL binds, file paths, and line numbers.

• 🛑 Zero Production Impact: Designed to run safely in development mode.
