agent-browser

To automate browser tasks and debug JavaScript-rendered pages, launch the agent-browser CLI against a URL to render the page, wait for network idle, and inspect the live DOM state. This enables scripted interactions and screenshots for complex web flows.

You need a headless browser instead of a plain HTTP fetch when targeting JavaScript-heavy pages that require client-side rendering. It enables live DOM inspection and browser automation for dynamic web apps and private SaaS dashboards where raw HTML fetching fails.

To extract data from private SaaS dashboards, use agent-browser to automate browser interactions, wait for network idle, and snapshot the DOM. This allows you to verify UI steps and capture state behind gated content during automated sessions.

Yes, you need a local Chromium runtime and the agent-browser CLI to inspect live DOM state. The runtime handles rendering JavaScript-heavy pages, while the CLI provides the automation interface and runtime hints referenced in its documentation.

The best way to capture screenshots of dynamic web app flows is using a headless browser automation tool like agent-browser. It renders JS-heavy pages, waits for network idle, and captures visual state and DOM snapshots for automated verification.

HTTP fetch returns empty content for JavaScript-heavy pages because it cannot execute client-side scripts. You must use a headless browser to render the page, wait for network idle, and inspect the fully rendered live DOM to extract data accurately.
