Selenium, Puppeteer, and Playwright are powerful — but they require ChromeDriver management, dependency hell, constant anti-bot maintenance, and zero fingerprint diversity. RelayKit Cloud Browser gives you a real, stealthy session in seconds with no code required.
Every Selenium and Playwright session exposes the navigator.webdriver flag in the browser's JavaScript context. Anti-bot systems check for this flag in milliseconds. Headless browsers also have distinctive fingerprints — window size, plugin list, hardware concurrency, and GPU renderer all deviate from real user patterns.
ChromeDriver versions must exactly match your Chrome version — a Chrome auto-update can break your entire scraping setup overnight. On Linux, you need display emulation (Xvfb), memory management, and process cleanup. Every team member needs the same environment configured.
Anti-bot systems update continuously. Cloudflare Turnstile, DataDome, PerimeterX — each new detection technique requires updates to your evasion code. What works today may fail next week. You're in an arms race against security teams with dedicated engineers.
All your Selenium or Playwright sessions share the same browser fingerprint. Platforms that track fingerprints across sessions can link all your activity together and flag the shared pattern — even across different IPs.
Hit a CAPTCHA and you need to integrate a third-party CAPTCHA service, manage API keys, handle rate limits, and pay separately. Every additional integration is another failure point in your automation pipeline.
There's no built-in proxy management. You paste credentials into your code, handle rotation logic yourself, and debug proxy-related failures in your script. Authenticated proxies in Selenium require browser extensions or third-party libraries.
| Feature | Selenium / Playwright | RelayKit Cloud Browser |
|---|---|---|
| Setup | Install ChromeDriver, manage version matching, Linux deps, memory config | Open dashboard, click Launch — ready in seconds |
| Bot detection | Exposes navigator.webdriver flag, detectable headless fingerprint | Real browser fingerprint — Extra Stealth mode spoofs Canvas, WebGL, AudioContext |
| Fingerprint diversity | All sessions share the same browser fingerprint | Each session gets a unique fingerprint |
| CAPTCHA handling | Requires third-party API (2captcha, CapSolver, etc.) — extra cost and integration | Built-in CAPTCHA solver (+$0.10/session) |
| Proxy setup | Paste credentials in code, manage rotation logic yourself | Select your RelayKit proxy from the launch dropdown |
| Maintenance | Constant updates needed as anti-bot systems evolve | Managed by RelayKit — no maintenance on your end |
| AI automation | Must write code for every action | Plain English task description — AI agent executes it |
| Session recording | Must implement yourself (or use a third-party tool) | Automatic, included free with every session |
| Cost | Free (open source) but hours of DevOps setup + ongoing maintenance | $0.25/session, pay per use — no monthly fee |
| Best for | Developers who need full programmatic control of every browser action | Anyone who needs a stealthy browser session without engineering overhead |
Go to Dashboard → Browser → click Launch. Select your proxy. Your session is live in under 10 seconds. No terminal, no ChromeDriver, no dependencies.
Spoofs Canvas fingerprint, WebGL renderer, AudioContext, navigator properties, and hardware signals. Each session generates a unique, realistic fingerprint that passes advanced checkers.
Describe what to do: "go to the pricing page, click the Enterprise plan, screenshot the feature list". The AI agent executes it — no XPath selectors, no CSS selectors, no code.
Add the CAPTCHA solver at launch (+$0.10). Handles hCaptcha, reCAPTCHA, Turnstile, and more automatically — no integration, no third-party API keys.
Every session records automatically at no extra charge. Replay the full browser session to debug issues, audit automation runs, or review what happened.
Your RelayKit mobile proxies appear in the session launch dropdown. Select one — it's connected. No proxy URL to format, no credentials to paste.
Launch a stealthy cloud browser session in seconds.
$0.25/session. Proxies included. No monthly fee.
