how do i know what ruby version my site was built with

If I didn’t specify a ruby version in my Gemfile

If I didn't specify a ruby version in my Gemfile

Look in the file that specifies which version of each gem to use.

You can see into .ruby-version file

If I didn’t specify a ruby version in my Gemfile then you can see the ruby version in .ruby-version file in your project directory which is created at the time of creating a project.

Well, kinda sorta maybe :slight_smile:

It's not created pre-Rails 5.0, and it's meaningless unless you're
using a version manager that recognizes that file.
