Web Scraping
Web Scraping That Doesn't Get Blocked
Sites with heavy anti-bot protection, JS-rendered content, and auth walls. Patched Chromium on a real OS, residential IPs, per-target payloads.

How Surfsky stays consistent
Automation is stripped at the build level, not hidden at runtime. Per-target payloads are tuned against live production detection stacks.
01 Transport
JA4+, HTTP/2 SETTINGS, header order, and sec-ch-ua-* come straight from Chromium, not replayed from a saved fixture. Each is tuned per target.
02 Environment
Hardware profiles match real devices: screen, CPU, memory, and media that fit together. Traffic exits on residential and mobile IPs matched to the session's timezone and locale, with WebRTC, UDP, and DNS on one network.
03 Runtime
A patched Chromium build on a real OS. Markers like navigator.*, window.*, and CDP artifacts are spoofed at the source, not at runtime. Canvas, WebGL, AudioContext, fonts, and permissions come from the real OS.
04 Behavior
Navigation chains, timing, and per-session state read like a real user's, because the browser is the real surface, not a script layered on top.
Built to beat the hardest blocks. Every antibot layer, defeated.
Cloudflare, Akamai, DataDome, PerimeterX, and more. Surfsky passes them all.
What actually happens when you get caught
When a scraper gets flagged, the response depends on how the anti-bot wants to waste your time. You'll see all of these.
Access denied
A blank 403 or a WAF block page. The cleanest failure — at least you know immediately.
Misleading HTTP errors
Cloudflare returns 5xx, Akamai returns 400 when JA4 doesn't match the UA. The status code points everywhere except at the actual block.
CAPTCHA
Cloudflare Turnstile, DataDome interstitial. Even if you solve it, the session is marked.
JS challenge loop
Cloudflare "Just a moment...", PerimeterX, DataDome. The interstitial is the response - real content is never served.
Rate limiting
A 429 that never leads to a clean response. The site is effectively closed to you, dressed up as a throttle.
Poisoned data
The worst outcome. HTTP 200, the page renders, and the data is fake — wrong prices, shuffled rankings, missing listings.
With Surfsky
Antidetect Chromium with real fingerprint, residential IP, persistent cookies. The response is the page you asked for.

CAPTCHA SOLVING
reCAPTCHA, Cloudflare Turnstile, DataDome, etc. solved auto when the target throws them.

PAYLOADS
Each target gets its own tuned config: fingerprint, transport, and behavior matched to that site's detection stack.

NOT QUARTERS
Anti-bot stack updates, payload ships. You don't rewrite your scraper.
CDP
DROP-IN
Point your existing Playwright or Puppeteer scripts at a Surfsky endpoint — same API, working browser.
Full browser or plain HTTP.
Same stealth.
Both modes run the same Chrome stack and the same residential network. The difference is how much control you need.
Live session you drive yourself
Multi-step flows, auth, dynamic UI, infinite scroll, anti-bot challenges that require real interaction.
- Playwright · Puppeteer · Selenium compatible
- Persistent profiles, cookies, local storage
- One websocket connection, full control
One request, one rendered response
For pages that load their data into the DOM and are done. No browser to manage — point, render, return.
- POST /render with URL + optional waitFor
- Returns HTML, screenshots, structured data
- Built-in retries on transient anti-bot flags
