WebDriver BiDi reference

WebDriver BiDi is a bidirectional protocol for browser automation that provides event-driven communication between the local end (the automation client) and the remote end (the browser). This reference documents the modules, commands, and events available in WebDriver BiDi.

Unlike the HTTP request-response model of WebDriver classic, BiDi enables real-time events and supports advanced automation scenarios through WebSocket-based communication.

Modules

Commands

Asynchronous operations to inspect and control the behavior of browsers, manage browser sessions and contexts, execute scripts, monitor network activity, interact with DOM elements, and emulate browser APIs.

Events

Notifications sent by the remote end (the browser) signaling that something of interest has occurred.
