Ransack will help you easily add searching to your Rails application, without any additional dependencies.

There are advanced searching solutions around, like ElasticSearch or Algolia. Ransack will do the job for many Rails websites, without the need to run additional infrastructure or work in a different language. With Ransack you do it all with standard Ruby and ERB.

Ready to move beyond the basics? Use advanced features like i18n and extensive configuration options.

Ransack is supported for Rails 7.0, 6.x on Ruby 2.6.6 and later.


To install ransack and add it to your Gemfile, run

gem 'ransack'
