Cloudflare Browser Rendering

Cloudflare Browser Rendering is a developer API that enables running headless Chromium browsers directly within Cloudflare Workers, bringing full browser automation capabilities to the edge. It supports use cases like web scraping, PDF generation, screenshot capture, and automated testing without managing any browser infrastructure. Built on Puppeteer, it integrates seamlessly into the Cloudflare Workers ecosystem and scales automatically with demand. Developers can access it through the Workers Binding API or the REST API.

• Headless Browser Execution: Run full Chromium instances inside Cloudflare Workers without provisioning or managing servers.
• Puppeteer Integration: Use the familiar Puppeteer API to control browser sessions, navigate pages, click elements, fill forms, and extract data.
• Screenshot & PDF Generation: Capture full-page screenshots or render pages to PDF programmatically for archiving, previews, or reporting.
• Web Scraping: Render JavaScript-heavy pages and extract structured data from dynamic websites that require a real browser environment.
• REST API Access: Interact with browser sessions via a REST API for use cases outside of Workers, including remote browser control.
• Workers Binding: Bind Browser Rendering directly to a Worker script for low-latency, co-located browser automation at the edge.
• Session Management: Create, reuse, and close browser sessions with fine-grained control over concurrency and lifecycle.
• Automatic Scaling: Leverage Cloudflare's global network to scale browser workloads without capacity planning.
• Durable Objects Support: Persist browser sessions across requests using Cloudflare Durable Objects for stateful automation workflows.
• Open Sessions Limit Control: Configure the number of concurrent open browser sessions per account to manage resource usage.
