A Ruby gem that detects N+1 queries, unused eager loading, and missing counter caches in ActiveRecord and Mongoid applications during development. It notifies developers through alerts, logs, and error-tracking integrations so they can optimize database query performance.

Use cases

• detect N+1 queries in a Rails app
• find unused eager loading
• identify where to add counter caches
• improve ActiveRecord query performance
• catch slow database queries during development
• add query performance checks to the test suite

When to choose

• you maintain a Rails or Mongoid application and want to eliminate N+1 query problems
• you want automated detection of unnecessary eager loading during development or testing
• you want query-performance alerts integrated with tools like Sentry, Honeybadger, or Rollbar

When to avoid

• your application does not use ActiveRecord or Mongoid
• you need production APM-style query monitoring rather than development-time detection
• you are not working in a Ruby/Rails stack
