Note: This blog post is a mirror of the README of my GitHub repository.

Using this project you can debug your websites and web applications running in iOS Safari from a PC running Windows or Linux.

It provides a free and up-to-date alternative to the discontinued remotedebug-ios-webkit-adapter by RemoteDebug and is the spiritual successor to the abandoned webkit-webinspector by Arty Gus.

The setup scripts ( or generate.ps1) download the latest version of WebKit’s built-in WebInspector and patch it to work with the WebSocket ios-webkit-debug-proxy provides and to be compatible with Chromium based browsers.

Requirements for running

  • ios-webkit-debug-proxy
    • On Windows, it will automatically be downloaded, but you must also install iTunes for it to work
    • For Linux, please follow the installation instructions.
  • Node.JS http-server or Python or PHP
    • If you have Python or PHP on your system, you don’t need to change anything
    • If you have Node.JS on your system, just run npm i -g http-server and you’re set.
  • A Chromium based browser
    • like Google Chrome, Edge or Opera
  • or WebKit based browser
    • like Epiphany/GNOME Web

Requirements for setup

  • svn (for or git (for generate.ps1) for downloading WebKit source code
    • On Windows, I suggest using git for Windows in PowerShell
    • On Linux, I suggest installing svn from your package manager



  1. Clone this repository, to your PC
  2. On Windows, run generate.ps1. On Linux, run

This will result in the folder WebKit being created inside src. It contains the WebInspector files.


  1. Plug your iOS device into your PC via USB
  2. On the iOS device, go to Settings->Safari->Advanced->Web Inspector and enable it
  3. Open the website you want to debug in Safari
  4. On Windows, run start.ps1. On Linux, run
  5. Then open the Chromium or WebKit based browser of your choice with the following URL: http://localhost:8080/Main.html?ws=localhost:9222/devtools/page/1
  6. You should be greeted with the WebInspector and can now debug to your heart’s content.



  • Two windows will open. One manages the web server and the other one is ios-webkit-debug-proxy.
  • To exit, close the ios-webkit-debug-proxy window, the other one will close automatically
    • Alternatively you can also press Ctrl+C in the web server window


  • Press Ctrl+C in the terminal window to exit

Known Issues

  • "Events" on the "Timelines" tab don’t work
  • Canvas content doesn’t show on the "Graphics" tab
  • Minor style glitches due to Webkit vs. Chromium differences

Hi, I just wanted to write and say THANK YOU VERY MUCH for making these scripts available, and also for taking the time to document everything. I had been pulling my hair out trying to just simply get proper error messages from iOS Safari console. Apple is totally unreasonable with their restricted access to the crippled web browser on iOS, and they furthermore prevent you from really having any other alternatives either because every browser is on iOS is still running the webKit engine as a rule. People like you, however, are making a difference, and I just wanted to say thanks for the effort. If there is a place to make a donation to you, I’d be willing to do so because you have saved me hundreds of dollars by circumventing the necessity to buy an actual Mac just to test my software against their awfully crippled browser, Safari. Your efforts are much appreciated. Thanks, Joe.
