thin-rails

thin-rails is a simple gem that sets the default server for rack (and rails) to thin.

thin-rails overrides the Rack::Handler.default method to return Rack::Handler::Thin which will cause rack (and rails) to use thin by default.

Add this line to your application's Gemfile:

gem "thin-rails"

And then execute:

$ bundle install

Just add the gem to your Gemfile and then rails server will default to using thin.
