Browser Support

Alumnium works by building an accessibility tree of the webpage. Unfortunately, there is no standard API in browsers to provide this tree. Due to this limitation, the current version of Alumnium only works in Chromium-based browsers such as Google Chrome, Microsoft Edge, Opera, and others.

Playwright driver supports both headful and headless modes, while Selenium driver only supports the headful mode.
