Rack::Bug is a debugging toolbar for Rack applications, implemented as Rack middleware. It injects a floating diagnostics panel into your app showing logging, SQL queries, template rendering times, cache usage, memory, and request variables.
Use cases
- inspect SQL queries in a Rails app during development
- profile template rendering and request timing in a Rack app
- debug cache and Redis usage from a browser toolbar
- add custom diagnostic panels to a Sinatra app
- securely enable a debug toolbar in staging with IP or password restrictions
When to avoid
- starting a new Rails project - use maintained alternatives like Rails panel gems or newer profilers
- you need actively maintained tooling or modern Ruby/Rails compatibility
