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


Available on Free and Paid plans

Browser Run, formerly known as Browser Rendering, enables developers to programmatically control and interact with headless browser instances running on Cloudflare’s global network.


Use cases


Programmatically load and fully render dynamic webpages or raw HTML and capture specific outputs such as:

Markdown

Screenshots

PDFs

Snapshots

Links

HTML elements

Structured data

Crawled web content


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

Key features


Scale to thousands of browsers: Instant access to a global pool of browsers with low cold-start time, ideal for high-volume screenshot generation, data extraction, or automation at scale

Global by default: Browser sessions run on Cloudflare's edge network, opening close to your users for better speed and availability worldwide

Easy to integrate: Quick Actions for common tasks, Puppeteer and Playwright for complex workflows, and CDP for direct browser control from any environment

Session management: Reuse browser sessions across requests to improve performance and reduce cold-start overhead

Flexible pricing: Pay only for browser time used with generous free tier (view pricing)
