Frequently Asked Questions
What is Cloud Browser API?
Cloud Browser API is a headless browser service that provides managed remote browser instances 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: 30,000+ browser signals spoofed from real device profiles across every JS API surface
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. With 500+ patched source files and 30,000+ spoofed browser signals, every session loads a real device profile covering Canvas, WebGL, WebGPU, Audio, Fonts, Speech, Media Devices, Screen and every JS API surface.
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.

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. With 500+ source-level Chromium patches, real device profiles, human-like interactions, and premium proxies, detection is 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.
