Readapt

July 11, 2026 ยท View on GitHub

A Ruby debugger that supports the Debug Adapter Protocol.

This project is no longer maintained. As of Ruby 3, the native rdbg debugger is capable of connecting to debug adapters, so Readapt is no longer necessary. For Visual Studio Code, the VSCode rdbg Ruby Debugger is a solid alternative.

Installation

Add this line to your application's Gemfile:

gem 'readapt'

And then execute:

$ bundle

Or install it yourself as:

$ gem install readapt

Usage
