In 2025, many platforms are now using more advanced account detection mechanisms to check users' account information and ban accounts that are deemed abnormal. Platforms like Amazon, TikTok, and eBay have increasingly stringent account detection systems. The official reason given is the proliferation of scammers/spam accounts and automated tools on these platforms, prompting more in-depth checks on all accounts.

However, the reality is that many banned accounts are not problematic ones, but legitimate marketers managing multiple accounts. Our research has found that frequently switching accounts on the same device, same IP address, or in geographically distant regions significantly increases the risk of account suspension.

For marketers managing multiple accounts across various regions, this issue must be addressed. Currently, there's only one effective solution on the market: using anti-detection browsers (also known as fingerprint browsers). These tools help create and fix unique user profiles for each account, preventing detection by platform systems. Many people may not have used such tools before, fearing high costs or ineffectiveness. Today, we introduce six of the most worthwhile and free anti-detection browsers to use in 2025.

What is an Anti-Detection Browser?

The core of an anti-detection browser is to assign a unique set of parameters to each browser instance, ensuring that duplicate profiles are not identified when platforms collect user information. Typically, such fingerprint browsers allow modification of cookies and cache, IP addresses, WebRTC data, font and language settings, geographic locations, device hardware parameters, and more. By configuring distinct settings for each account, platforms will be unable to detect or link these accounts together.

FAQs：

Q1: What is an anti-detection browser?

A1: An anti-detection browser (fingerprint browser) is a special browser tool that generates an independent environment and a unique browser fingerprint for each account, including parameters such as cookies, cache, IP address, WebRTC, fonts, and geolocation. This way, even if you operate multiple accounts on the same device or IP address, you can avoid being identified and banned by platforms.

Q2: Why do I need a multi-account anti-detection browser?

A2: Many platforms (such as Amazon, TikTok, eBay) implement strict detection on accounts. If you switch accounts on the same device, same IP address, or from geographically distant locations, even multiple accounts under normal operation may be banned. An anti-detection browser makes each account appear to be operated on a separate device, thereby reducing the risk of account suspension.

Q3: Which platforms do these free anti-detection browsers support?

A3: Most of these browsers support common platforms such as e-commerce (Amazon, eBay, Walmart), social media (Facebook, Instagram, TikTok), and advertising. Different products may have differences in mobile or desktop support; please refer to their official websites for details.

Q4: What is the difference between free and paid versions of anti-detection browsers?

A4: Free versions usually offer basic features and a limited number of accounts/profiles. For example, MostLogin provides complete browser fingerprint features for free, and Incogniton offers 10 free local profiles. However, advanced automation, cloud expansion, or more accounts may require a paid upgrade, depending on the design of each vendor.
