Mobile debugging methodology

Patterns for accessing JavaScript console and debugging web pages on mobile devices without traditional desktop DevTools.

Quick-start: Inject console on any page

Eruda bookmarklet (recommended)

Add this as a bookmark on your mobile browser, then tap it on any page:

javascript:(function(){var script=document.createElement('script');script.src='https://cdn.jsdelivr.net/npm/eruda';document.body.append(script);script.onload=function(){eruda.init();}})();

vConsole bookmarklet

javascript:(function(){var script=document.createElement('script');script.src='https://unpkg.com/vconsole@latest/dist/vconsole.min.js';document.body.append(script);script.onload=function(){new VConsole();}})();
