Page Modeller Autor: Dan Humphrey

Browser DevTools extension for modelling web pages for automation.

Pick an element on any page — or scan a whole form at once — and Page Modeller names it, works out a locator that resolves to it, and generates page object style code you can paste into your tests.

Currently generates code for:

• Playwright (TypeScript)
• Playwright (Python)
• Selenium WebDriver Java
• Selenium WebDriver C#
• Selenium WebDriver Python
• Puppeteer

Each target offers a full page object or just the locators, and Selenium also generates methods — so it fits whatever conventions your project already has.

Version 3 is a complete rewrite. It runs in Chrome and Firefox, reaches elements inside iframes and inside a web component's shadow DOM, prefers accessible roles and names over brittle CSS paths, and checks that every locator it gives you actually resolves to the element you picked.
