RouteGuard

RouteGuard is a production-ready static analysis tool for Rails routing. It inspects your Rails routes to catch issues Rails itself doesn't report—like shadowing, duplicates, unreachable catch-alls, and duplicate resource blocks.

• Duplicate Route Detection: Detects routes sharing the same HTTP verb and path pattern.
• Route Shadowing: Flags routes that can never be matched because an earlier route matches first (e.g. /users/:id shadowing /users/new).
• Unreachable Routes: Detects routes defined after catch-all wildcard routes (e.g. match "*path").
• Duplicate Named Helpers: Identifies duplicate helper names (e.g., duplicate auth_path helpers pointing to different paths).
• Duplicate Resources: Warns when identical resources are declared multiple times in the same namespace scope.
• Route Statistics: Computes REST resources count, nested scopes, and wildcards.
• Health Score: Measures a 0-100 maintainability score based on issues and path nesting levels.

Add this gem to your group :development, :test block:

group :development, :test do
  gem "route_guard", path: "path/to/route_guard"
end

Run bundle install.

Run check from the terminal:

Or execute via Rake tasks:
