deivid-rodriguez/byebug: Debugging in Ruby

23-Jan-2026 481
Byebug is a simple to use and feature rich debugger for Ruby. It uses the TracePoint API for execution control and the Debug Inspector API for call stack navigation. Therefore, Byebug doesn't depend on internal core sources. Byebug is also fast because it is developed as a C extension and reliable because it is supported by a full test suite. The debugger permits the ability to understand what is going on inside a Ruby program while it executes and offers many of the traditional debugging features such as: Stepping: Running your program one line at a time. Breaking: Pausing the program at some event or specified instruction, to examine the current state. Evaluating: Basic REPL functionality, although pry does a better job at that. Tracking: Keeping track of the different values of your variables or the different lines executed by your program.
