Cloud browser that
passes anti-bot challenges
For scraping, automation, and AI agents. 98% success rate across every major anti-bot system.
The stack 200+ teams trust to get through
You write the logic. We handle everything between your code and the target site.
8 to 1,000+ concurrent sessions
Parallel Browsers
Scale to hundreds of browsers at once. Each with its own fingerprint, proxy, and isolated network.
2.5M+ devices, 8,000 new daily
Real Device Fingerprints
Canvas, WebGL, Audio, Fonts, GPU, Screen, WebRTC and 20+ more parameters -desktop and mobile. All consistent, all leak-proof.
10+ captcha types, auto-solved
Anti-Captcha
Bypass challenges automatically. When bypass isn't possible - solve inside the browser. Cloudflare, DataDome, Akamai, reCAPTCHA, PerimeterX and more.
15+ behavioral signals emulated
Human Emulation
Kinematic mouse movements with hand tremor and fatigue. Realistic typing with rhythm, typos, and self-corrections.
100M+ IPs, 98% success rate
Residential Proxies
100M+ IPs. SOCKS5 + HTTPS with full UDP. WebRTC, QUIC, HTTP/3 work correctly. Or use your own proxies.
Integration from 2 hours
Any Framework
Playwright, Puppeteer, Selenium, chromedp - connect via CDP or use the HTTP API. No SDK required.
Works on real protected sites

THE PROBLEM
"Cloudflare blocked my bot"
You launch Playwright / Selenium script on a VPS. Cloudflare runs 5+ checks at once: TLS fingerprint doesn't match the User-Agent. HTTP/2 frame parameters expose a non-browser client. Canvas fingerprint has no real GPU. navigator.webdriver is true. Datacenter IP has a bad reputation score. Error 1010 - access denied.
It's getting worse. Google now requires JavaScript to render Search results - simple HTTP requests don't work anymore. Cloudflare traps suspicious crawlers in an endless labyrinth of fake pages. You try Stealth plugin - Cloudflare already fingerprints it. You try undetected-chromedriver - works for a day, then breaks. The challenge scripts are obfuscated and rotate every session.
WITH SURFSKY
Kernel-level browser patches - not detectable by known anti-bot vendors. TLS, HTTP/2, Canvas, WebGL, Audio fingerprints from a database of millions of real desktop and mobile devices, updated with new signatures daily. Every parameter is consistent - OS, GPU, fonts, screen, etc. never contradict each other. Cloudflare sees a real user.
THE PROBLEM
"Captcha solved, still access denied"
You click the Turnstile checkbox - challenge loops, page never loads. You solve the DataDome slider - access denied anyway. You send reCAPTCHA to a solver API, inject the token - the site sees a spoofed environment and rejects it. Each anti-bot has its own challenge type, and solving the captcha alone isn't enough if the browser fingerprint already failed.
WITH SURFSKY
Real browser fingerprint + residential proxy + human emulation = most challenges are bypassed before they even appear. When proof-of-work challenges do appear, solved in-browser with our own solver. The combination is what makes it work, not just the solver alone.
THE PROBLEM
"My proxy says US, but WebRTC leaks my real IP"
You set up a SOCKS5 proxy. WebRTC still leaks your real IP. You disable WebRTC - anti-bot flags the missing feature. Pages load over HTTP/2 but WebRTC goes over UDP - the inconsistent network profile is a red flag. DNS leaks through, QUIC and HTTP/3 bypass the tunnel entirely. Anti-bot sees a contradictory fingerprint.
WITH SURFSKY
Full UDP support at the network engine level. WebRTC, QUIC, HTTP/3, WebTransport, DNS - everything goes through the proxy tunnel. No inconsistencies, no leaks. The browser behaves like regular Chrome on a home PC. 100M+ residential and mobile IPs built-in, or bring your own.
THE PROBLEM
"Site detects my bot because my actions don't look human"
Playwright's click() fires mousedown and mouseup at the same millisecond - no cursor movement at all. You add a "human-like" mouse library, but anti-bots analyze the velocity profile of every trajectory and run ML classifiers on it. The math patterns your library uses are already fingerprinted.
Same with typing. You add random delays between keystrokes, but anti-bots build a biometric profile of every session - timing patterns, rhythm, press-release intervals. Random or uniform delays don't look like a real person.
WITH SURFSKY
Mouse moves along a real trajectory with natural acceleration, micro-tremor, and speed variation - no synthetic patterns for classifiers to detect. Typing produces keystroke timing that matches real biometrics: rhythm, natural typos, self-corrections. Key presses have realistic press/release dynamics. All input events work through CDP.
THE PROBLEM
"It worked last week. They updated their anti-bot again."
Anti-bot vendors now update their defenses weekly, sometimes daily. A fix that used to hold for weeks now breaks in days. The WAF industry is worth $11 billion - they have dedicated teams shipping detection updates around the clock. Your team patches it, it works for a few days, then breaks again.
WITH SURFSKY
A team with 5+ years in browser internals and anti-bot reverse engineering monitors updates and ships patches before you notice. Your code stays the same. You ship product.
Highest success rate in the industry
Most providers use general-purpose browsers with proxy rotation. Surfsky is an anti-detect browser built from the ground up to solve anti-bot.

The most boring code you'll ever write
No SDK to learn. No config ritual. Connect via CDP with your favorite framework and go grab coffee.

We get through all of these
They update their defenses. We update ours. Your code stays the same.
