Cloudflare Browser Rendering
Your AI agent renders web pages on Cloudflare's global network, captures pixel-perfect screenshots, scrapes structured data from HTML elements, and delivers full DOM snapshots. All from a single conversation, running on headless browsers with near-zero cold start.
Capture screenshots, extract page data, and render full snapshots through headless Chromium instances on Cloudflare's edge, triggered by your AI agent in real time.
Cloudflare Browser Rendering
From competitive monitoring to compliance archiving, see how AI agents use headless browsers on Cloudflare's edge to capture, scrape, and analyze web content automatically.
Your marketing team wants daily screenshots of a competitor's pricing page. Your AI Agent navigates to the URL using Cloudflare's headless browser, captures a full-page screenshot with a desktop viewport, and stores the image. When someone asks for changes, the agent compares today's capture with last week's. Visual intelligence without manual browsing.
Your procurement team needs current pricing from three supplier websites. Your AI Agent scrapes each page using CSS selectors targeting price elements, extracts the text and attributes, and compiles a comparison table in the conversation. The agent handles JavaScript-rendered pages that traditional scrapers miss because it runs real Chromium on Cloudflare's network.
Regulations require your legal team to archive published terms and conditions pages weekly. Your AI Agent takes a full snapshot of each page, capturing both the rendered HTML and a screenshot in one request. The DOM text provides searchable records while the screenshot serves as visual proof of what was displayed on the capture date.

FAQs
It runs headless Chromium instances on Cloudflare's global edge network. Pages render with full JavaScript execution, CSS rendering, and modern web API support, identical to what a real Chrome browser would display. This means dynamic, JavaScript-heavy sites are captured accurately.
Yes. Because Browser Rendering executes real Chromium, it handles single-page applications, dynamically loaded content, and lazy-loaded elements. The agent can set a waitForSelector or waitForTimeout to ensure target elements are fully rendered before scraping begins.
Your API Token requires the 'Browser Rendering - Edit' permission. Create the token in your Cloudflare dashboard under My Profile, API Tokens. You also need to provide your Cloudflare Account ID, found on the Workers & Pages overview page.
Yes. The screenshotOptions parameter accepts a clip object with x, y, width, and height values to capture a specific rectangular region. Alternatively, set fullPage to true to capture the entire scrollable page beyond the viewport.
Every endpoint accepts a cacheTTL parameter in seconds. Set it to a positive integer to cache results for that duration, reducing repeated renders of the same page. Set cacheTTL to 0 to disable caching and always get a fresh render.
No. Screenshots and scraped HTML data are returned directly in the API response during the conversation. Tars does not persist rendered content, DOM snapshots, or image captures. If you need long-term storage, configure your agent to export results to your own storage system.
Yes. The scrape endpoint accepts an array of CSS selectors in the elements parameter. The agent extracts text, innerHTML, attributes, and bounding box dimensions for every matching element across all provided selectors in a single API call.
Running headless browsers on your infrastructure requires managing Chromium installations, handling memory, and scaling capacity. Cloudflare Browser Rendering runs on their global edge network with near-zero cold start, built-in caching, and no server maintenance. Your agent gets browser access without provisioning any compute resources.
Don't limit your AI Agent to basic conversations. Watch how to configure and add powerful tools making your agent smarter and more functional.
