Rack BuiltWith

Serve a builtwith.txt file from your Ruby on Rails or Rack application so you can remove your site from BuiltWith. 🙅‍♀️

Add this line to your application's Gemfile:

gem "rack-builtwith"

And then execute:

$ bundle

Or install it yourself as:

$ gem install rack-builtwith

If you're using Rails, you can add the middleware in an initializer:

# config/initializers/rack-builtwith.rb

Rails.application.middleware.use Rack::BuiltWith

or add it to any rack application in your rackup config:

# config.ru

use Rack::BuiltWith

run [200, {}, ["Hello, world!"]]

By default, the middleware will respond to "/builtwith.txt" on any host with the correct hostname. You can force it to use the same host in the response, regardless of the request host, by specifying an argument to the middleware:

use Rack::BuiltWith, "example.com"

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in the gemspec, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
