DeadweightRails

DeadweightRails scans your Rails project for unused assets and Ruby code, helping you reduce bundle size, improve performance, and clean your codebase.

• Detect unused CSS and JS in Rails asset pipeline
• Detect unused Ruby methods
• Generate a report in terminal with colored output
• Works with standard Rails directories (app/assets, app/views, app/models)
• Simple Rake task integration

Add this line to your Gemfile:

gem 'deadweight_rails'

Then execute:

bundle install

Or install it yourself:

gem install deadweight_rails

Add this task to lib/tasks/deadweight.rake:

require "rake"
require "deadweight_rails"

namespace :deadweight do
  desc "Scan Rails project for unused assets and Ruby code"
  task :scan do
    DeadweightRails.run
  end
end

Run the task:

bundle exec rake deadweight:scan

require "deadweight_rails"

# Scan current Rails project
DeadweightRails.run

# Or scan a specific path
DeadweightRails.run(path: "/path/to/project")
