ZenRows Scraping Browser

What It Is

ZenRows Scraping Browser is a cloud-based browser infrastructure service that lets you run Playwright or Puppeteer scripts against a managed Chromium fleet backed by over 55 million residential IPs across 190+ countries. You connect via a single WebSocket URL and your existing automation code runs as-is, with anti-bot evasion, IP rotation, and geolocation targeting handled transparently by ZenRows.

It is purpose-built for scraping JavaScript-heavy sites and single-page applications (SPAs) where headless HTTP fetching fails. ZenRows manages the browser lifecycle, proxy rotation, and fingerprinting so you do not have to.

Safety and ToS Notes

ZenRows Scraping Browser is a commercial infrastructure service. Usage is governed by ZenRows Terms of Service. Key points:

• You supply the target URLs; ZenRows routes them through residential IPs.
• Scraping sites in violation of their own Terms of Service is your responsibility, not ZenRows.
• ZenRows does not guarantee bypass of all bot-detection systems.
• High-bandwidth usage (images, fonts, video) runs up session time and bandwidth costs fast. Block unnecessary resource types to control spend.
• Do not store your API key in version-controlled code. Use environment variables.
