Browser Run
Run headless Chrome on Cloudflare's global network for browser automation, web scraping, testing, and content generation.

Integration methods
Browser Run offers two categories of integration methods:
- Quick Actions: Simple, stateless browser tasks like screenshots, PDFs, and scraping. No code deployment needed.
- Browser Sessions: Direct browser control via Puppeteer, Playwright, CDP, or Stagehand. Deploy within Cloudflare Workers or connect from any environment via CDP.
| Use case | Recommended | Why |
|---|---|---|
| Simple screenshot, PDF, or scrape | Quick Actions | No code deployment; single HTTP request |
| Browser automation | Playwright, Puppeteer, or CDP | Full browser control with scripting |
| Porting existing scripts | Puppeteer, Playwright, or CDP | Minimal code changes from standard libraries |
| AI-powered data extraction | JSON endpoint | Structured data via natural language prompts |
| Site-wide crawling | Crawl endpoint | Multi-page content extraction with async results |
| AI agent browsing | Playwright MCP or CDP with MCP clients | LLMs control browsers via MCP |
| Resilient scraping | Stagehand | AI finds elements by intent, not selectors |
| Direct browser control from any environment | CDP | WebSocket access from local machines, CI/CD, or external servers |
