Scrapfly is the **best Anchor Browser alternative** when real stealth shouldn't cost $2,000/mo. Scrapium ships source-level stealth on the $30 entry plan, drops into your existing Playwright or Puppeteer code over CDP, and bypasses Cloudflare, DataDome, and Akamai without depending on vendor allowlists. - **Source-level stealth at $30** Scrapium ships at the entry tier, no $2,000/mo gate. - **CDP-native drop-in** Existing Playwright/Puppeteer code works unchanged. No SDK rewrite. - **Bypass without allowlists** Cloudflare, DataDome, Akamai bypass that doesn't depend on vendor cooperation. - **Human-in-the-loop CAPTCHA** Real humans solve hCaptcha and reCAPTCHA v3 when bots fail. - **AI agent frameworks** Browser Use and Stagehand work out of the box.

Teams come to this page for one of three reasons. **Stealth degraded** after an antibot vendor update and runtime patches got detected. **Cost surprised them** via per-hour minimums or browser-time multipliers. Or they need **features Anchor Browser doesn't ship**: manual control for debugging, session resume, browser extensions, and human-in-the-loop CAPTCHA solving. Scrapfly's [Cloud Browser API](https://scrapfly.io/products/cloud-browser-api) addresses all three on the same key, and you can compare it side by side with [Browserbase](https://scrapfly.io/compare/browserbase-alternative), [Browsercloud](https://scrapfly.io/compare/browsercloud-alternative), or [CloudBrowser.ai](https://scrapfly.io/compare/cloudbrowserai-alternative). --- OVERVIEW## Anchor Browser at a glance.

[Scrapium](https://scrapfly.io/scrapium) is a custom Chromium fork. Fingerprints are emitted by the browser itself, not spoofed in JavaScript. // FINGERPRINTS##### Real TLS, HTTP/2, WebGL, Canvas Authentic [JA3/JA4](https://scrapfly.io/web-scraping-tools/ja3-fingerprint), [HTTP/2](https://scrapfly.io/web-scraping-tools/http2-fingerprint), [WebGL](https://scrapfly.io/web-scraping-tools/webgl-fingerprint), [canvas](https://scrapfly.io/web-scraping-tools/canvas-fingerprint). Match the Chrome builds target sites expect. // CHALLENGE SOLVING##### Adaptive bypass Handles [Cloudflare](https://scrapfly.io/bypass/cloudflare), [DataDome](https://scrapfly.io/bypass/datadome), [PerimeterX](https://scrapfly.io/bypass/perimeterx), [Akamai](https://scrapfly.io/bypass/akamai) automatically. // FORK##### Source-level mods Chromium modified at the C++ source level. The browser is *genuinely different*, not patched after launch. // WHY SOURCE-LEVEL WINS##### Anchor Browser's stealth is detectable. Scrapium isn't. Runtime stealth modifies `navigator.webdriver`, `navigator.plugins`, and a few other JS surfaces after the page loads. Modern antibot vendors fingerprint exactly that pattern. Scrapium's fingerprints are produced by the browser itself, so there's nothing to detect. // SCRAPIUM- Source-level Chromium modifications - Native fingerprint emission - Undetectable by JS-property checks // ANCHOR BROWSER- Runtime JS-property overrides - Spoofed fingerprints applied post-load - Detectable by modern anti-bot vendors --- AI AGENTS## Plug your agent into Scrapfly's CDP endpoint. Stealth browser, integrated proxies, and human-in-the-loop CAPTCHA. Everything an agent needs. // BROWSER USE **Python / TypeScript** An open-source framework wrapping Playwright with an LLM-driven control layer, Python and TS SDKs included.

Production tooling keeps them. // ANTI-BOT##### Pass the toughest detections Cloudflare, DataDome, Akamai, PerimeterX. Scrapium's source-level stealth holds where runtime patches fail. // PROXIES##### Integrated, no second vendor Premium residential & datacenter pools across 190+ countries, billed in the same credit pool as your browser time. // SCALE##### Run as many browsers as you need No infrastructure to manage, no per-browser provisioning.

Scrapium is Scrapfly's custom Chromium fork, built from source with deep anti-detection modifications. Unlike Anchor Browser'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 Anchor Browser? Anchor Browser 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 Anchor Browser 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 Anchor Browser 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](https://scrapfly.io/docs/cloud-browser-api/browser-use) and [Stagehand](https://scrapfly.io/docs/cloud-browser-api/stagehand). The CDP WebSocket connection provides stealth browsers with integrated proxies and human-in-the-loop CAPTCHA solving. That combination is what AI agents need for 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 and reCAPTCHA v3), Scrapfly routes the challenge to real humans. This provides significantly higher success rates on tough CAPTCHAs. ### How does Scrapfly compare to other Anchor Browser alternatives?
