Browser Run
Headless, programmable web browsers built for AI Agents
Give your application web browsing capabilities. Spin up a web browser in the cloud on-demand, and control it with your own code or AI-generated code. Take screenshots, extract text, run tests and automate any workflow even ones with no API to rely on.
Scale to thousands of browsers
Instant access to a global pool of browsers with low cold-start time ideal for screenshotting, extracting structured data, or automation at scale.
Global by Default
Runs on Cloudflare's global network, opening browser sessions close to users for better speed and availability.
Easy to Integrate
REST APIs for common actions, and works with Playwright and Puppeteer, the best-in-class browser automation libraries
Made for Programmable Browsing
Global Pool of Browsers
Deployed on Cloudflare's network. Enables faster cold starts and lower latency across use cases.
REST API Support
Browser Rendering offers easy, fast setup for tasks like screenshotting, extracting content, generating PDFs, snapshotting and capturing structured data with JSON or markdown for AI.
Supports common browser libraries
Playwright & Puppeteer support. Gives developers full control when needed with standard automation tools.
"Well-behaved" Bot Mode
Identifies itself as a bot using cryptographic signatures. Ensures compliant, ethical scraping distinguishes Cloudflare from competitors that bypass bot protections.
[Background Pattern] Browser Run Ideal for Agentic Workflows
You can use Browser Rendering to:
View docsCreate website thumbnails and social previews using the /screenshot REST API
Generate visual previews for websites and social media sharingPower AI agents that need browser-based automation where APIs don't exist
Enable AI agents to interact with web pages and extract dataGenerate PDFs from webpages and HTML content using the /pdf REST API
Convert web content to PDF format for documents and reportsHeadless browsers on standby that you can use at scale without any complicated setup
Eliminate the need to manage complex browser infrastructure by running browser-based tasks like screenshots and PDF generation on Cloudflare's global network.

Take screenshots of web pages using the REST API or Workers bindings. See docs.Run Playwright for powering agentic workflows
Use Playwright to automate complex browser interactions for AI agents. See docs.Retrieve webpage and generate markdown for AI consumption
Extract content from web pages and convert to markdown format for AI processing. See docs.Lovable
"
We needed a reliable way to capture screenshots at scale, and Cloudflare Browser Rendering solved it with a single API call. It was remarkably easy to implement and handles all our traffic without a hiccup. "
