Stress Testing in Ruby on Rails 4

Question

Can someone please point out the best tools for stress testing in Rails 4. I know that there are already some questions on this subject but the ones I managed to find all seemed outdated.

If someone could point me to a similar question that would be great also.

Thanks in advance!

Sendgrid recently came out with a pretty nice free solution that works for web or API endpoints.

Worked great for me:
