VisBrowser: Visual Browsing Adapter for Playwright Python

VisBrowser is a visual browsing adapter for Playwright Python that enables navigation and interaction with web pages based on visual information rather than CSS selectors. It provides a high-level API for performing actions like clicking, typing, and waiting for elements using visual cues such as text and images. With VisBrowser, you can automate web browsing tasks by leveraging the visual layout and content of the page, making your scripts more resilient to changes in the underlying HTML structure. Particularly useful for website which doesn't give a proper dom, like fuller website, or websites using HTML canvas.

Installation

To install the Visual Browser Adapter, use pip:

pip install git+https://github.com/hargup/visbrowser.git
