Different code bases and teams usually just end up with a bespoke debugger, there are multiple available. There’s the default debugger, byebug, pry debug and I believe Rubymine uses one called debase, under the hood. You can use whichever you want but usually one will be specified in your project Gemfile because someone on the team likes that particular debugger and added it long ago.
