byebug
Byebug is a Ruby 2.0 debugger. It's implemented using the Ruby 2.0 TracePoint C API for execution control and the Debug Inspector C API for call stack navigation. The core component provides support that front-ends can build on. It provides breakpoint handling and bindings for stack frames among other things and it comes with an easy to use command line interface.
