Frequently Asked Questions

What is Cloud Browser API?

Cloud Browser API provides managed browser instances in the cloud that you can connect to via WebSocket CDP (Chrome DevTools Protocol). It's powered by Scrapium — our custom Chromium fork with deep anti-detection patches. You can use it with Playwright, Puppeteer, or any CDP-compatible tool to run browser automation at scale without managing infrastructure.

How is this different from regular Playwright/Puppeteer?

Unlike running Playwright or Puppeteer locally, Cloud Browser API provides:

Stealth: Scrapium browser has source-level patches to avoid detection by anti-bot systems
Fingerprint Coherence: End-to-end consistent fingerprints (TLS, HTTP/2, browser APIs) that don't trigger red flags
Integrated Proxies: Premium residential proxies built-in with automatic rotation
Zero Infrastructure: No servers to manage, browsers auto-scale on demand

What is Scrapium?

Scrapium is Scrapfly's custom Chromium browser fork, purpose-built for web automation and scraping. Unlike vanilla Chromium or Chrome, Scrapium includes deep source-code modifications that make browser automation undetectable. This includes patches for Canvas, WebGL, Audio fingerprinting, as well as coherent TLS and HTTP/2 signatures that match real browsers.

Can I use my existing Playwright/Puppeteer code?

Yes! That's the beauty of Cloud Browser API. You only need to change your connection method from launch() to connect_over_cdp() (Playwright) or connect() (Puppeteer). Point to our WebSocket endpoint with your API key, and all your existing code works immediately. No rewrites needed.

How does pricing work?

Cloud Browser API has two pricing dimensions:

Browser Time: You're charged for the duration your browser session is active (per minute)
Bandwidth: You pay for the data transferred through the browser

This model ensures you only pay for actual usage. There are no minimum commitments, and you can start with free credits to test the service. View detailed pricing

Is Cloud Browser API suitable for AI agents?

Absolutely! Cloud Browser API is designed with AI agents in mind. AI-powered automation tools need reliable, stealth browser access for web navigation, data collection, and multi-step workflows. The CDP WebSocket connection works seamlessly with popular AI frameworks, and the managed infrastructure means your agents can focus on their tasks without worrying about browser failures or anti-bot blocks.

What anti-bot systems can it bypass?

Cloud Browser API with Scrapium can bypass most common anti-bot systems including: Cloudflare, DataDome, PerimeterX/HUMAN, Akamai, Kasada, Shape Security, and many others. The combination of deep browser patches, coherent fingerprints, and premium proxies makes detection extremely difficult.

How many concurrent browsers can I run?

Cloud Browser API supports massive concurrency. Free tier users start with limited concurrent sessions, while paid plans can scale to thousands of simultaneous browser instances. The infrastructure auto-scales based on your demand, so you don't need to pre-provision capacity. Contact us for enterprise plans with custom concurrency limits.
