# CloudBrowser.ai Alternative

##  Scrapfly Cloud Browser API 

 CloudBrowser.ai **basic stealth mode** helps with simple detection, but it can't bypass advanced antibot shields. Scrapfly's **Scrapium** browser provides **full fingerprint coherence** at the source level, plus **integrated proxies** and **human-in-the-loop CAPTCHAs**.

 

- **Scrapium vs Stealth Mode** — Source-level patches vs runtime modifications that can be detected
- **Session resume** — Reconnect to existing browser sessions using the same identifier
- **Manual control & debugging** — Debug failed scrapes, video recording, and human-in-the-loop CAPTCHAs
- **AI agent frameworks** — Browser Use and Stagehand ready out of the box
- **CDP connection** — Connect with any CDP-comptiable tool, including Playwright and Puppeteer

  ##  [Powered by Scrapium](#scrapium) 

Custom Chromium fork with source-level anti-detection patches

  

### TLS Fingerprint Matching

Authentic [JA3/JA4 signatures](https://scrapfly.io/web-scraping-tools/ja3-fingerprint) that match real Chrome browsers at the TLS layer.

 

 

 

  

### HTTP/2 Coherence

Perfect [HTTP/2 fingerprints](https://scrapfly.io/web-scraping-tools/http2-fingerprint) including SETTINGS frames and header order.

 

 

 

  

### Canvas & WebGL

Consistent [canvas](https://scrapfly.io/web-scraping-tools/canvas-fingerprint) and [WebGL](https://scrapfly.io/web-scraping-tools/webgl-fingerprint) fingerprints across sessions.

 

 

 

 

### Why Source-Level Patches Matter

Scrapium modifies Chromium at the C++ source code level, producing a browser that's genuinely different, not just patched with JavaScript overrides that anti-bot systems can detect.

 

#### Scrapfly

- Source-level mods
- Native fingerprints
- Undetectable
 
 

#### CloudBrowser.ai

- Runtime patches
- JS property overrides
- Detectable by anti-bot

  ##  [Connect in Seconds](#code-example) 

Switch your existing scripts to use Scrapfly's cloud browsers with a single line change



    python  

 ```
from scrapfly import ScrapflyClient, BrowserConfig
from playwright.sync_api import sync_playwright

client = ScrapflyClient(key="YOUR_API_KEY")

# Configure the Cloud Browser session (proxy pool, OS fingerprint,
# session pinning, block rules, captcha solver, etc.)
config = BrowserConfig(
    proxy_pool="datacenter",
    os="linux",
)

# SDK builds the signed wss:// URL with all options encoded
ws_url = client.cloud_browser(config)

with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp(ws_url)
    context = browser.contexts[0]
    page = context.pages[0] if context.pages else context.new_page()

    page.goto("https://web-scraping.dev/products")
    print(page.title())
    browser.close()
```

 

 

 

    javascript  

 ```
import { ScrapflyClient, BrowserConfig } from 'scrapfly-sdk';
import puppeteer from 'puppeteer-core';

const client = new ScrapflyClient({ key: 'YOUR_API_KEY' });

// Configure the Cloud Browser session (proxy pool, OS fingerprint,
// session pinning, block rules, captcha solver, etc.)
const config = new BrowserConfig({
  proxy_pool: 'datacenter',
  os: 'linux',
});

// SDK builds the signed wss:// URL with all options encoded
const wsUrl = client.cloudBrowser(config);

const browser = await puppeteer.connect({ browserWSEndpoint: wsUrl });
const page = await browser.newPage();

await page.goto('https://web-scraping.dev/products');
console.log(await page.title());
await browser.close();

  ##  [Frequently Asked Questions](#faq) 

  ### What is Scrapium and how is it different from CloudBrowser.ai?

 Scrapium is Scrapfly's custom Chromium browser fork, built from source with deep anti-detection modifications. Unlike CloudBrowser.ai's approach which applies runtime patches, Scrapium's fingerprint coherence is baked into the browser at the source code level. This makes it undetectable by advanced anti-bot systems.

 

   ### How does Scrapfly's stealth compare to CloudBrowser.ai?

 CloudBrowser.ai uses runtime stealth patches that modify browser properties via JavaScript overrides. Advanced anti-bot systems can detect these modifications. Scrapium is a custom Chromium fork where fingerprints (TLS, HTTP/2, Canvas, WebGL) are coherent at the source level — they match because the browser actually produces them, not because they're spoofed.

 

   ### Can I use my existing CloudBrowser.ai code with Scrapfly?

 Yes! Both services use CDP (Chrome DevTools Protocol) over WebSocket. Change your connection endpoint to Scrapfly's URL and your existing Playwright or Puppeteer code works immediately.

 

   ### What features does Scrapfly offer that CloudBrowser.ai doesn't?

 Scrapfly offers manual control for debugging failed scrapes, video recording of browser sessions, session resume to reconnect to existing browsers, and Chrome extension support. These features help you diagnose issues and handle edge cases that pure automation can't solve.

 

   ### Does Scrapfly work with AI agent frameworks?

 Yes! Scrapfly's Cloud Browser API integrates with Browser Use and Stagehand. The CDP WebSocket connection provides stealth browsers with integrated proxies and human-in-the-loop CAPTCHA solving — perfect for AI agents that need reliable web access.

 

   ### Are proxies included in Scrapfly?

 Yes. Scrapfly includes premium residential and datacenter proxies across 190+ countries. You don't need a separate proxy provider. Proxy usage is included in your browser API credits.

 

   ### What is Human-in-the-Loop CAPTCHA solving?

 When automated CAPTCHA solvers fail (common with hCaptcha, reCAPTCHA v3, and Cloudflare Turnstile), Scrapfly routes the challenge to real humans. This provides significantly higher success rates on tough CAPTCHAs.
