PonyDebugger is a remote debugging toolset. It is a client library and gateway server combination that uses Chrome Developer Tools on your browser to debug your application's network traffic and managed object contexts.

To use PonyDebugger, you must implement the client in your application and connect it to the gateway server. There is currently an iOS client and the gateway server.

PonyDebugger is licensed under the Apache Licence, Version 2.0 (

Quick Start

curl -sk | \
  python - --ponyd-symlink=/usr/local/bin/ponyd ~/Library/PonyDebugger

This will install ponyd script to ~/Library/PonyDebugger/bin/ponyd and attempt to symlink /usr/local/bin/ponyd to it. It will also download the latest chrome dev tools source.

Then start the PonyDebugger gateway server

ponyd serve --listen-interface=

In your browser, navigate to http://localhost:9000. You should see the PonyGateway lobby. Now you need to integrate the client to your application.

For more detailed instructions, check out the gateway server README_ponyd.

iOS Client Library

Right now, integrating the iOS client requires a few steps, so you should check out the iOS Client PonyDebugger README.
