ruby-packer is what I use to distribute a paid CLI, although on macOS only because my product is specifically for customers on macOS.
The advantage of ruby-packer is that it is much simpler, but you need to have access to each OS where you want to distribute your executable. OTOH, with traveling-ruby, you can build executables for all OSes from the same machine.
