Navigating online privacy in 2025 isn't just about using incognito mode anymore. Whether you're managing multiple accounts, conducting market research, or testing geo-targeted content, anti-detect browsers and fingerprinting tools have become essential. This guide walks you through the landscape of anti-detection technology—from browsers that mask your digital footprint to testing tools that reveal exactly what websites can see about you.

Anti-Detect Browsers: What Works and What Doesn't

The anti-detect browser market has exploded, but not all solutions deliver on their promises. Here's what you need to know.

Solid Options Worth Considering

Gologin offers 3 free profiles for a month, then $24 for 100 profiles. No unlimited plan exists, but free proxies are included. Automation isn't supported on the free tier.

Undetectable gives you 5 cloud profiles free. For $49 you get unlimited local profiles with 25 "configs"—each additional config costs $1. API and driver automation support is available but not on the free plan.

NSTBrowser is relatively new. The free tier allows 10 profile opens per day. Jump to $29 monthly (or $299 annually) and you can open 3,000 profiles daily. Automation is supported even on free accounts.

Multilogin starts at €74 monthly for 100 profiles. It's one of the older, more established players.

Incogniton provides 10 free profiles for 2 months, dropping to 3 afterward. Paid plans start at $29.99 for 50 profiles monthly, but automation isn't available on free plans.

AdsPower limits free users to 2 profiles. For $5.40 you get 10 profiles, though there's no unlimited option. No automation on free plans.

Morelogin offers 2 free profiles, with paid plans starting at $9 for 10 profiles and 2 users. Automation is supported across all tiers.

Dolphin-anty includes 5 free profiles. The 100-profile plan runs $89, and automation is available even for free users.

If you're working with tighter budgets or need more flexibility, exploring proxy solutions alongside your anti-detect browser can multiply your capabilities without multiplying costs. 👉 Discover how combining residential proxies with anti-detect browsers creates an unbeatable privacy setup

RoxyBrowser provides 5 free profiles with per-profile pricing ranging from $0.03 to $0.8. Oddly, they also offer free Netflix access.

Octo Browser starts at €21 for 10 profiles.

Kameleo begins at €59 per user with unlimited profiles.

Bablosoft offers a free browser automation studio. For Puppeteer users, check out puppeteer-with-fingerprints—it's the only browser supporting canvas faking through PerfectCanvas. Fair warning: PerfectCanvas is slow, yielding only 30-40 canvases daily unless you purchase CustomServer. Automation is supported.

Camoufox launches via Python and runs on Firefox. Automation works out of the box.

BitBrowser gives 10 free profiles, then 50 for $9. This anti-detect browser originates from Hong Kong and supports automation.

Browsers to Skip

AntBrowser fails basic fingerprint tests—CreepJS catches too many inconsistencies.

Switch Antidetect runs Chrome 103 when version 120+ is current. Updates are painfully slow.

GhostBrowser only switches user-agents, making it trivial to fingerprint.

MarketerBrowser can't even change user-agents without triggering detection.

Testing Your Digital Fingerprint

Before trusting any anti-detect solution, test it. These tools reveal what websites actually see.

Comprehensive Fingerprint Checkers

Creep JS provides advanced fingerprint analysis—it's the gold standard for catching inconsistencies in browser implementations.

Pixelscan offers straightforward fingerprint checking without overwhelming detail.

F.vision represents the evolution of the classic f.vision checker.

Coveryourtracks from EFF tests whether your setup protects against fingerprinting.

BrowserLeaks includes numerous different checks for various fingerprinting vectors.

My own tool at reviewer.eugenebos.com/test has one benefit: the code is plain JavaScript, making it easy to understand exactly how each test works.

BrowserScan rounds out the basic fingerprint checking options.

Automation Detection

Rebrowser-bot-detector presents an interesting challenge: you automate tasks while it tries detecting your bot. It's excellent for testing real-world scenarios.

Brotector represents the most advanced detector available—it can even crash automation when detection occurs.

Behavioral Bot Classification analyzes how you interact with pages.

Pixelscan Bot detector works but shows false positives for Firefox inside KVM MacOS environments.

Canvas Fingerprinting

Canvas inspector helps identify scripts on websites that generate canvas and audio fingerprints.

Canvas Tampering Detection reveals whether your canvas modifications are detectable.

Captcha Scoring

ReCaptha score at antcpt.com shows your reCaptcha score.

Cloudflare captcha checker at nowsecure.nl verifies if you're passing Cloudflare challenges.

Connection Testing

ProxyDetect catches proxy and VPN usage by implementing the NikolaiT/zardaxt library.

IPRoyal WebRTC leak and BrowserLeaks WebRTC leak both detect WebRTC leaks that expose your real IP.

ipQualityScore checks IP reputation, though it hilariously flags many legitimate Russian IPs as VPNs. It has an API.

FingerBank provides API access for checking TCP fingerprints by signature.

DnsLeakTest and BrowserLeaks DNS leak both catch DNS leaks.

Anti-Detect Libraries and Tools

For Puppeteer

Imposter (my own project, currently in development) emulates human actions on pages.

Rebrowser provides an isolated environment for Puppeteer.

Secure-puppeteer offers isolation but is outdated—XPath and some features don't work.

Extra stealth gets detected easily by CreepJS. Skip it.

Fingerprints from Bablosoft offers both free and paid fingerprints.

Perfect Canvas from Bablosoft emulates real canvas data.

For Playwright

Rebrowser works with Playwright too.

Playwright-ghost adds plugins to make Playwright stealthier.

For Selenium and Python

NoDriver succeeds Undetected-chromedriver.

ZenDriver is a NoDriver fork.

Undetected-chromedriver is now outdated.

Pyautogui controls mouse and keyboard for automating other applications.

Selenium-Driverless runs Selenium without chromedriver.

For Request Libraries

Curl-impersonate mimics real browser requests at the HTTP level.

CycleTLS works for NodeJS and GO.

curl_cffi brings curl-impersonate to Python.

Got-Scraping handles scraping in NodeJS.

Humanizing Your Automation

Raw automation screams "bot." These tools add human-like behavior.

Fake-browser builds on Puppeteer with human-like interactions baked in.

Bezier mouse movements creates realistic cursor paths.

Definitely-not-a-robot, Puppeteer-Humanize, and Ghost-Cursor all generate realistic mouse movement data between coordinates.

Supporting Services

SMS Verification

SmsActivate requires minimum $2.50 top-up with high commissions.

VakSms has limited country availability.

SmsHub appears cheapest but quality varies—specifying operators sometimes helps.

GrizzlySms, 5Sim, OnlineSim, SmsBower, 365sms, and Cyberyozh offer alternatives at various price points.

Proxies

Understanding proxy infrastructure is crucial. Residential proxies appear as real user connections, while datacenter proxies are faster but more detectable. Mobile proxies offer the highest trust scores but cost more.

Check out my separate lists for comprehensive proxy provider comparisons—the Proxy Providers List covers 25+ providers with pricing, while the 4G proxies list includes smaller mobile proxy providers.

BrightData runs around $8/GB.

DataImpulse starts at $1/GB with a $5/5GB welcome package, though normal top-ups are $50+. IMAP/SMTP is blocked.

WebShare charges $6/GB (down from $4.50) with shared IPs from $6/month for 20. IMAP/SMTP works.

Thordata offers residential from $1.80/GB and mobile from $2.20/GB.

GeoNode prices at $4/GB (down from $1.70).

LunaProxy runs $3/GB (down from $0.80) with static options at $3/week or $5/month. IMAP/SMTP is blocked.

Anti-Detection Tips That Actually Work

Use a separately downloaded Chrome version instead of Chromium—pass it in executablePath with Puppeteer.

Screen dimensions are tricky. Extensions can modify width/height via debugger, but screen.availHeight and availWidth stay wrong. Change screen size at the VM level or use anti-detect browsers.

Disable WebRTC when using proxies to prevent IP leaks.

Match all browser headers in the correct order—inconsistencies flag bots immediately.

Check that none of your scripts appear in global scope. Some websites collect all window.* properties and analyze them.

Here's something sneaky: if you navigate directly to a website without searching for it first, window.history.length reveals this. Real users typically search first.

Workers: The Hidden Fingerprinting Vector

JavaScript Workers represent a sneaky detection vector. You can't modify object properties in Workers with extensions because window, screen, and DOM access aren't available—canvas fingerprinting doesn't work there either.

Wrapping Up

Anti-detection in 2025 requires layering multiple strategies. No single browser or tool provides complete protection—websites continuously evolve their detection methods. Test your setup regularly with the fingerprint checkers mentioned above. Combine anti-detect browsers with quality proxies, add humanization libraries to your automation, and stay current with new detection techniques.

The tools listed here represent what's working now, but this landscape shifts constantly. Some browsers overpromise and underdeliver, while others quietly excel. Test before committing to paid plans, join Discord communities to learn from other users, and remember that perfect anonymity doesn't exist—you're aiming for "sufficiently undetectable" for your specific use case.

For serious multi-account work or web scraping at scale, professional proxy infrastructure becomes non-negotiable. 👉 Start building your privacy-first automation setup with reliable residential proxies
