> Are there any popular non-Rails uses for Ruby? Hardly. And that bothers me as a Ruby (not rails) developer. There was Chef, still is around, but Chef "lost" from Ansible and Terraform. There are some commandline tools, but I slowly see them replaced by Go, Rust, node or Python versions. `github`, `heroku` etc. And there are numerous small or tiny platforms, systems and toolkits that failed to get traction and live a (happy!) live with a tiny audience. Think about sinatra, sequent, gosu, (the ruby version of) cucumber, kiba-etl, etc. But I'm pretty sure most of these tools, frameworks and platforms are there because or Rails. To cater people, shops and teams "that already know Ruby inside out" (because of Rails) and therefore choose their, say, ETL system in Ruby too.
