Headless tells on itself
Default Chromium builds leak automation signals through JS APIs, WebGL, fonts, and navigator properties that Turnstile and Bot Fight Mode score in milliseconds.

Test Cloudflare Turnstile in a real Cloud Browser
The hero below is our full Cloud Browser configurator. We prefill Cloudflare’s own public Turnstile demo so you can sign in and one-click launch a live session—no fake unblocker=true switch.

Prefills https://demo.turnstile.workers.dev/. Official Cloudflare Turnstile Workers demo (implicit rendering). Stable public page that hosts a real Turnstile widget so Cloud Browser can be tested against the captcha vendor's own experiment.

Why DIY stalls
Stock browsers trip Cloudflare long before your scraper runs
Cloudflare evaluates more than a User-Agent string. Homegrown Playwright setups usually fail on network reputation, TLS/HTTP fingerprint gaps, or interactive Turnstile challenges.
Clean datacenter IPs get challenged
Even a perfect browser fingerprint fails when the request originates from obvious cloud ranges. Residential or mobile egress is part of the story.
Partial spoofing breaks consistency
Patching one layer (canvas) while leaving another (TLS JA3 / HTTP2) mismatched is a common DIY failure mode.
Challenge loops burn your pipeline
Retries without a durable browser profile create endless Turnstile widgets and wasted compute—exactly what Cloud Browser is designed to avoid.
What Cloud Browser covers
Aligned fingerprints across the layers Cloudflare scores
Use the configurator above to tune proxy, locale, and browser fingerprint settings—the same controls available in /app/cloud-browser.
01
TLS / HTTP
Session transport that stays consistent with a real desktop browser profile.
02
Headers & client hints
Accept-Language, client hints, and related signals stay coherent with the chosen OS/UA.
03
JS runtime
A full browser runtime executes Turnstile’s client scripts the way a user session would.
04
Canvas / WebGL
Fingerprint controls for graphics surfaces that bot detectors routinely hash.
05
Live interaction
Watch the session live, solve or observe challenges, and keep the profile for follow-up steps.
We guide you into Cloud Browser sessions rather than inventing a proprietary unblocker=true API flag. Your proof is a live browser against Cloudflare’s own demo.
One-click path
From this page to a live Turnstile check
Unauthenticated visitors can explore the full input UI. Credits are only used after you authenticate and start a session.
Step 1
Review the prefilled demo URL
The hero configurator already points at Cloudflare’s Turnstile Workers demo. Tweak proxy or fingerprint if your scenario needs it.
Step 2
Sign in and pick an API key
Starting a session uses the same auth gate as the Home playground—login modal first, then API key prompt if needed. Nothing runs silently while logged out.
Step 3
Watch Turnstile in the live browser
After start, the live preview (or /app/cloud-browser deep link) opens the demo so you can see whether the session clears the widget.
FAQ
Cloudflare bypass questions
What is Cloudflare Turnstile?
Turnstile is Cloudflare’s CAPTCHA alternative. It runs client-side challenges that score browser and network signals. We use Cloudflare’s public demo page as the default test target so you can evaluate Cloud Browser against the vendor’s own widget.
How does Cloud Browser help with Cloudflare?
Cloud Browser gives you a remote, configurable browser with proxy and fingerprint controls plus a live view. Instead of guessing from HTTP status codes, you open a real session on the Turnstile demo and observe the result.
Do you have an unblocker=true API flag?
No. Our product path is Cloud Browser—configure the session, start it after login, and inspect the live browser. We intentionally do not mirror competitor-only API flags.
Will opening this marketing page burn credits?
No. Browsing the page is free. Credits are consumed only when an authenticated user starts a Cloud Browser session with a valid API key, matching the existing playground behavior.
Is bypassing Cloudflare allowed?
Only access sites and data you are authorized to use. Cloud Browser is infrastructure for legitimate automation, testing, and data collection under applicable laws and site terms.
