WebdriverIO DevTools

A powerful browser devtools extension for debugging, visualizing, and controlling test executions in real-time.

Works with WebdriverIO, Nightwatch.js, Selenium WebDriver (any test runner), and Python Selenium — same backend, same UI, same capture infrastructure.

It runs in two modes: live — an interactive dashboard that opens as your tests run — and trace — a portable trace.zip artifact for offline replay, CI, and AI-agent diffing.

Quick Start

Install the adapter for your framework, add it to your config, and run — the DevTools dashboard opens automatically.

npm install @wdio/devtools-service --save-dev   # WebdriverIO (Nightwatch / Selenium below)

// wdio.conf.js
export const config = {
  services: ['devtools'] // live mode — opens the dashboard on run
}

npx wdio run wdio.conf.js
