Do Cloudflare, reCAPTCHA, and Fingerprint Pro detect antidetect browsers?
Real anti-bot checks are worth 35 of the 100 points in our benchmark. We ran 12 antidetect browsers through Cloudflare challenge pages, the reCAPTCHA v3 score, and the smart signals of Fingerprint Pro. Before each product, stock Chrome ran the same checks on the same IP.
Direct answer
Most browsers got through, but most were flagged. In our test on 2026-10-28/29, 8 of 12 browsers passed all 3 Cloudflare challenge pages, and MoreLogin Chrome and GoLogin passed none. reCAPTCHA v3 gave every browser 0.9. Fingerprint Pro saw browser tampering on 9 of 12 and a virtual machine on 6. Only AliasMode Firefox and Donut Browser had no flag. On the IP of every product, stock Chrome passed the first Cloudflare page, scored 0.9, and had no flag.

Cloudflare
Each browser opened three public Cloudflare managed-challenge pages: scrapingcourse.com, zerocaptcha.io, and capskip.com. A page passes when the challenge clears with no click within 30 seconds. We never clicked the “Verify you are human” checkbox. Stock Chrome passed page 1 on the IP of every product, and passed pages 2 and 3 on one of the test IPs before we used them.
AliasMode Firefox, Dolphin Anty, Camoufox, Octo Browser, CloakBrowser (free 146), DICloak, AdsPower SunBrowser, and AdsPower FlowerBrowser passed all three pages. MoreLogin Chrome and GoLogin stopped at the checkbox on all three pages. Donut Browser stopped at the checkbox on page 2.
The first page sets a clearance cookie that lasts a year, so tries 2 and 3 used other domains. Cloudflare first counted as one try. On 2026-10-29, after the results, we changed it to 3 pages for every browser, because one try proved too random.
reCAPTCHA v3
reCAPTCHA v3 gives each visit a score from 0.0 to 1.0. A higher score looks more like a person. On the antcpt.com score detector, every browser scored 0.9, and so did stock Chrome on the same IPs. So in this test, reCAPTCHA v3 did not separate the browsers. Every browser got the full 11.2 points for it.
Fingerprint Pro
Fingerprint Pro, on the public Fingerprint demo playground, reports smart signals for each visit. We scored three of them. Bot looks for automation. Browser Tampering looks for browser values that were changed or faked. Virtual Machine looks for signs that the browser runs in a virtual machine.
Fingerprint Pro flagged 10 of 12 browsers. It saw tampering on 9 and a virtual machine on 6. CloakBrowser (free 146) was the only browser flagged as a bot. It is a library, and it ran through its own Playwright-based API. Only AliasMode Firefox and Donut Browser had no flag.
Stock Chrome on the same IPs had no flag at all. So the flags come from the browsers, not from the IPs or the server.
Why DataDome is not in the results
The plan had a DataDome check: the GitHub sign-up page must load with no block and no captcha. Stock Chrome was blocked with “Access is temporarily restricted” on every IP where we tried it, 12 in all. So the server or its IP range is flagged, and the check could not tell one browser from another. We dropped it for every browser and spread its 10 points over the other three checks.
What this means for your accounts
Each site decides what to do with a flag: let the visit through, show a check, or block it. In our test, AliasMode Firefox passed all 3 Cloudflare pages, scored 0.9 on reCAPTCHA v3, and had no Fingerprint Pro flag. AliasMode is free, with unlimited profiles on one device.

Which antidetect browser passes Fingerprint Pro?
AliasMode Firefox and Donut Browser had no bot, tampering, or virtual machine flag in our test. AliasMode Firefox also passed all 3 Cloudflare pages.
What reCAPTCHA v3 score do antidetect browsers get?

Why was DataDome dropped?
Stock Chrome was blocked on every IP where we tried DataDome, so the check could not separate the browsers. Its points went to Cloudflare, reCAPTCHA v3, and Fingerprint Pro.
