Webhook Based Request Response Streaming And Real Time Callbacks

via “real-time websocket streaming for browser events and session monitoring”

🔥 Open Source Browser API for AI Agents & Apps. Steel Browser is a batteries-included browser sandbox that lets you automate the web without worrying about infrastructure.

Unique: Implements WebSocket streaming as a first-class plugin in the PluginManager architecture, allowing multiple concurrent clients to subscribe to the same session's events without blocking. Events are streamed directly from CDP without buffering, enabling true real-time visibility.

Provides real-time event streaming that Puppeteer doesn't expose natively; enables reactive agent logic based on page state changes, whereas Puppeteer requires polling or manual event listener setup.
