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
CloudBrowser.ai Overview
CloudBrowser.ai offers cloud browser API with basic puppeteer stealth capabilities. Limited fingerprint control compared to Scrapium.

Scrapfly
CloudBrowser.ai
Powered by Scrapium
Custom Chromium fork with source-level anti-detection patches
TLS Fingerprint Matching
Authentic JA3/JA4 signatures that match real Chrome browsers at the TLS layer.
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

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.
