I wrote about my experience distributing Ruby apps to users that don’t have Ruby on their machines via Tebako at https://terminalwire.com/articles/tebako. Overall, I’ve been really pleased! The biggest surprise is that my binaries weigh in at 15 MB (compare that to 450 MB for Heroku’s CLI). There are a few other things you’ll want to think about if you choose Tebako for your CI workflows and file paths that I go over. Hope this helps if you’re also crazy like me and think about distributing Ruby apps as installed software.
