Which Anti-Detection Browser Is Really Stable? In-Depth Review

Cross-border e-commerce sellers, social media matrix operators, and advertising teams ask the same question every day: "Which anti-detection browser is truly stable?" While there are many tools on the market, issues like WebRTC leaks, inconsistent fingerprints, and detection system breaches still occur frequently. This review conducts a hands-on comparison of four mainstream tools: OctoBrowser, Dolphin Anty, GoLogin, and Undetectable. We use professional fingerprint detection services like PixelScan and Creep.js to verify their true stealth capabilities, helping you find a solution that is "truly usable and won't let you down."

Why This Review?

Choosing an anti-detection browser isn't just about whether it's "usable," but more crucially, "how long until you get detected?" Cross-border teams dread:

• Having 10 shop accounts banned overnight after just setting them up.
• Ad accounts triggering risk controls after two weeks of advertising.
• Proxy IPs appearing normal, yet the system flagging them as "suspicious devices."

These issues often stem not from poor proxy quality, but from inadequate browser fingerprint management—WebRTC leaks, duplicate Canvas fingerprints, client Hints not matching User-Agent, and other details that are prime targets for platform detection. This review uses real tools, standard procedures, and verifiable methods to identify who can truly "maintain a stable environment without revealing any flaws."

Review Methodology and Environment

To ensure fair and reproducible results, we employed the following process:

Testing Environment

• Brand new virtual servers (to avoid interference from historical data)
• All four browsers updated to their latest versions
• Identical proxy IPs and User-Agent parameters used to create profiles

Detection Tools

1. PixelScan: Detects anomalies in Canvas, WebGL, fonts, behavioral signals, etc.
2. Creep.js: Deeply analyzes fingerprint consistency, outputting a trust score and the number of anomalies.
3. BrowserLeaks: Verifies WebRTC, IP leaks, and client Hints alignment.

Number of Tests

• Each test item was repeated 3 times, with the average value taken.
• Representative run results are displayed in the article.

Core Capability Comparison of Four Browsers

Key Takeaways:

• All browsers passed PixelScan Basic Detection, indicating that their default configurations meet the threshold for "not obviously suspicious."
• Dolphin's WebRTC leak is a critical flaw: even with a proxy, the real IP exposure renders all isolation efforts useless.
• OctoBrowser and Dolphin lead in User-Agent and fingerprint detail handling, with fewer anomalies reported by Creep.js.
• GoLogin and Undetectable have minor flaws in GPU/audio fingerprint spoofing, triggering more inconsistency warnings.

OctoBrowser: Why the Highest Overall Score?

Strongest Fingerprint Consistency, Strictest Anomaly Control

In Creep.js's deep detection, OctoBrowser averaged only 2 anomalies, significantly below the industry average. This implies:

• The generation logic for Canvas, WebGL, and Audio fingerprints is more aligned with real browser behavior.
• Precise alignment across multiple dimensions like Client Hints, User-Agent, and screen parameters.
• It avoids being flagged by detection systems for details like "GPU model mismatching the OS."

This ability to "leave no trace" is crucial for cross-border e-commerce and advertising teams focused on long-term stable operations.

Suitable Scenarios

• Account management on high-risk platforms (Facebook, Google Ads, TikTok, etc.)
• Multi-shop matrix operations (Amazon, eBay, Shopify independent stores)
• Strong team collaboration needs, requiring permission-based profile management

Dolphin Anty: A "Work in Progress" Hampered by WebRTC

Obvious Advantages

Dolphin performs excellently in User-Agent consistency and Creep.js anomaly control, with basic fingerprint spoofing capabilities on par with OctoBrowser.

Fatal Flaw

WebRTC leaking the real IP is an unacceptable fundamental defect:

• Even with proxy configuration, STUN requests still expose the local IP.
• This is a "strong signal" in any anti-fraud system.
• It's akin to entering a building with a mask on, but leaving behind a copy of your real ID.

Impact:

• Greatly increases the risk of cross-border e-commerce multi-account association.
• Social media ad accounts are highly susceptible to device anomaly detection.
• Cannot guarantee client privacy and security when used by proxy teams.

Unless Dolphin officially fixes its WebRTC blocking logic completely, it is not recommended for high-risk operations.

GoLogin & Undetectable: Mediocre but with Room for Improvement

Common Issues

Both browsers presented ~3 anomalies in Creep.js detection, primarily related to:

• Logical matching between GPU model and operating system version.
• Subtle differences in Audio Context fingerprint generation.
• Some JavaScript object behaviors not aligning with real browsers.

While not fatal flaws, these could be identified as "suspicious devices" by sophisticated risk control systems (like Facebook Pixel, Google behavioral analysis).

Suitable Scenarios

• Low to medium-risk operations (content scraping, market research, automated testing)
• Budget-conscious teams prioritizing cost-effectiveness
• Short-term projects or testing purposes

Real-World Scenario: Cross-Border E-commerce Multi-Shop Operations

Task Background: Managing 15 Amazon stores, each with an independent IP and device fingerprint.

OctoBrowser Real-World Performance

• All stores operated normally for 60+ days, with no associated risk warnings.
• Profile import/export was convenient, allowing team members to quickly take over accounts.
• The automatic proxy rotation function was stable, with no IP leaks or fingerprint conflicts.

GoLogin User Feedback

• In the third week, 2 stores triggered "Suspicious Login Device" prompts (accounts were not banned).
• Manual adjustment of Canvas noise parameters was required to restore normal operation.
• Suitable for operation teams with some technical expertise.

Dolphin Risk Alert

• Due to WebRTC leaks, some stores were flagged by Amazon for "suspicious multi-account activity."
• Not recommended for use on platforms with strict risk controls.

FAQ: Common Questions About Choosing Anti-Detection Browsers

Can all anti-detection browsers prevent WebRTC leaks?

Not necessarily. This review shows that Dolphin Anty has WebRTC leak issues, while OctoBrowser, GoLogin, and Undetectable all block it normally. Always verify with tools like BrowserLeaks when selecting a browser.

How many anomalies from Creep.js are acceptable?

Based on our tests, 2–3 anomalies are within the normal range; even real browsers might trigger some trust warnings. However, if anomalies exceed 5, it usually indicates significant flaws in fingerprint spoofing.

Can anti-detection browsers completely prevent account association?

No. Browsers only address the issue of "device fingerprint and IP isolation." Account association also involves:

• Behavioral patterns (login times, browsing habits)
• Payment methods and receiving accounts
• Shipping addresses and contact information

A truly effective risk reduction strategy requires combining these browsers with sound account operation strategies.

In which scenarios is OctoBrowser essential?

• High-value ad accounts (Google Ads, Facebook Corporate Accounts)
• Cross-border e-commerce multi-shop matrices (Amazon, eBay, Shopify)
• Proxy businesses requiring team collaboration with permission-level management
• Long-term projects with extremely high demands for account longevity

How does MasLogin perform in this type of review?

MasLogin is also deeply customized based on Chromium and is in the same tier as OctoBrowser regarding fingerprint isolation stability and team collaboration features. Key advantages include:

• Session persistence mechanism: Even after closing the browser, logins and cached data are retained upon reopening.
• Automation friendly: Supports mainstream automation frameworks like Selenium/Puppeteer.
• Flexible proxy management: Allows assignment of independent proxy pools for different profiles.

If your business involves frequent account switching, automated operations, and team collaboration, MasLogin is a worthwhile option for deep evaluation.

Selection Recommendations: Match Tools to Business Scenarios

Final Thoughts

The core value of an anti-detection browser is not "whether it can be used," but "how long it can be used without being caught." This review has proven with verifiable methods that:

• OctoBrowser performs best in overall stealth.
• Dolphin, despite its highlights, has a fatal flaw with its WebRTC leak.
• GoLogin and Undetectable are suitable for low to medium-risk scenarios.

If your business has extremely high demands for account security, consider OctoBrowser or MasLogin first. The latter offers advantages in automation support and team collaboration, making it particularly suitable for proxy studios and cross-border e-commerce teams.
