Standard HTTP scrapers fetch the raw HTML response — but modern web applications render their content in the browser after the page loads. If you send a plain HTTP request to a React app, a Next.js site, or a dashboard built on a JavaScript framework, you get an empty shell with no data. You need a real browser that actually runs the JavaScript.

Stealth Scraper's `stealth_scrape` skill loads the full page in a headless browser with anti-bot evasion active, waits for dynamic content to render, and extracts the actual page content. Sites that block conventional scrapers or return CAPTCHAs to obvious bots are scraped reliably without intervention.

Developers, data engineers, and research teams use this to extract content from SPAs, pull data from dashboards that require JavaScript execution, and collect content from sites that actively detect and block automated HTTP clients.

How to scrape javascript-rendered pages with Claude, ChatGPT, Microsoft Copilot, and OpenClaw

Use Claude with Stealth Scraper to pull content from JavaScript-heavy sites and immediately analyze or transform what comes back. Claude handles the extraction request and then applies logic to the returned content — parsing structured data from rendered HTML, summarizing page content, or identifying specific fields to extract.

How to scrape javascript-rendered pages with Claude

Once connected (see setup above), use the Stealth Scraper tool:

  1. Provide the URL of the JavaScript-rendered page you want to scrape.
  2. Ask Claude to use `stealth-scraper` with `stealth_scrape` to load and extract the page content.
  3. Ask Claude to identify the specific data fields you need from the rendered content.
  4. Have Claude return the extracted data in your preferred format — JSON, markdown table, or plain text.

Example prompt for Claude

Try this with Claude using the Stealth Scraper tool
Use stealth-scraper to scrape this JavaScript-rendered product page: https://example.com/products/widget. Extract the product name, price, availability status, and all specifications listed on the page. Return the data as a JSON object.

Tips for Claude

  • Specify what you want extracted rather than asking for the raw HTML — Claude can parse and structure the data from the rendered content.
  • For pages with lazy-loaded content, mention that you need all sections to load before extraction.
  • If the page requires scrolling to reveal content, ask Claude to note this so the right extraction approach is used.
