no doubt, one of the best awesome repos and for a widely used language!

While it is probably the most customizable and flexible gem for file uploads, it might be too complex. I personally prefer to use a paperclip, carrierwave, or activestorage when I need to have just a simple file upload.

I must admit that I was originally very skeptical about this tool. But it's really powerful and I see the value of using it.

Of course, it really depends on your case, but I can recommend it. At least to try.

Highly recommended gem if you need to display any string diff (ala "git diff") in your Ruby app. It can also display the output in HTML.

An excellent gem to mock (and "record") your requests in the specs.

Sometimes a bit annoying to re-record cassettes, but not a big deal.

Every Ruby/Rails dev must know this gem.

Nice and lightweight wrapper around the Calendly API, for Ruby apps.
